# Secret Agent Voicemail > AI voicemail with voice authentication. Callers leave a message with an AI agent; after you pass your challenge phrase, the same agent can text a contact, transfer your call, read your saved reminders, search the web, and check or change your Google Calendar, from any phone. ## What it is A subscription voicemail service from WebMax Labs LLC. Each subscriber gets a dedicated US phone number answered by an AI agent, plus a web dashboard. Nothing is installed on the phone you call from. ## Who it is for People who want a voicemail that screens and entertains callers day to day, and a way to reach their contacts by voice from a borrowed phone or a landline if they lose their own phone or cannot use it. ## For callers (standard mode) - The agent answers with the owner's greeting, in one of 6 voices (Adam, Brian, Mike, Serena, Jessica, Kim) and one of six personalities: Default, Jester, Comedian, Granola, Jaded, Karen. Personalities can be set per contact. - Callers saved in the owner's contacts are greeted by first name. - Messages arrive in the dashboard with a transcript and the recording. Each one is also emailed to the owner with a summary (on by default), and an optional text alert goes to the owner's phone. - Optional spam detection checks unknown numbers and hands likely spam to one of four spam-handler personalities. ## For the owner (secure mode) Call your own number and say "Activate my Secret Agent". The agent asks for your challenge phrase, which is checked on the server, with two tries per call. After that, by voice: - Look up a contact's phone number, email, or address. - Text one contact a message you dictate. - Transfer the call to a contact or to any US phone number, such as a business found by web search. The transfer ends the session with the agent. - Hear the reminders you saved (up to three, for example medical or legal notes). - Search the web. - With Google Calendar connected: hear upcoming events, find an event, and cancel or reschedule it after spoken confirmation. It does not send group or broadcast messages and does not share your location. ## Plans - Monthly: $6.49 per month. - Annual: $67 per year, about 14% less than paying monthly. - Both plans include every feature. New subscribers get a 30-day free trial, once per account; the first charge is on day 31. - Cancel any time from the Account page through the Stripe billing portal. Cancellation takes effect at the end of the paid period. Paid periods are not refunded. ## FAQ ### What is Secret Agent Voicemail? Secret Agent Voicemail is an AI voicemail service. You get a dedicated phone number answered by an AI agent in the voice and personality you choose. Callers leave a message, and you get the transcript and the recording in your web dashboard, an email with a summary of each message, and a text alert if you turn one on. When you call your own number and pass voice authentication, the agent works for you instead: it can look up a contact, text a contact, transfer your call, read your saved reminders, search the web, and check or change your Google Calendar. All of that works from any phone. ### How much does Secret Agent Voicemail cost? There are two plans: $6.49 per month, or $67 per year, which works out about 14% cheaper than paying monthly. Both plans include every feature. New subscribers start with a 30-day free trial, and the first charge is on day 31. ### Is there a free trial, and can I get a refund? New subscribers get a 30-day free trial with every feature. Your card is not charged until day 31, and if you cancel before then you pay nothing. The trial is available once per account. After the trial, a paid billing period is not refunded, including the unused part of a period you cancel. ### What is the Secret Challenge Protocol? It is how you prove to your agent that you are the owner. Call your own Secret Agent number and say "Activate my Secret Agent." The agent asks for your challenge phrase, which you set in Settings. The phrase is checked on our server, not by the AI, and you get two tries per call. Once you pass, the call switches to secure mode. Anyone who does not know the phrase only reaches your voicemail. ### What can the agent do once I am authenticated? In secure mode you can ask it to look up a contact's phone number, email, or address; text one of your contacts a message you dictate; transfer your call to a contact or to any US phone number, such as a business it just found for you; read back the reminders you saved (up to three, like medical or legal notes); search the web; and, if you connected Google Calendar, tell you what is coming up and cancel or reschedule an event after you confirm out loud. Transferring the call ends your session with the agent. ### Can it send an alert to all my contacts at once? No. There is no group or broadcast message, and the agent does not share your location. It texts one contact at a time with the message you dictate, so to reach several people you ask it to text each of them. It can also transfer your call to a contact. All of this needs you to pass voice authentication first. ### Does it block spam calls? If you turn on spam detection, calls from numbers that are not in your contacts are checked against a spam lookup. When a number scores above your threshold (70% by default), a spam handler answers instead of your normal greeting. You choose which one: Quick Dismiss, Time Waster, Confused Elder, or Bureaucrat. People in your contacts always skip the check. ### Can I choose the voice and personality? Yes. There are 6 voices (Adam, Brian, Mike, Serena, Jessica, and Kim) and six personalities: Default, Jester, Comedian, Granola, Jaded, and Karen. Set one personality for everyone, then override it for individual contacts, so family and work callers can hear different styles. Callers saved in your contacts are greeted by their first name, and you can write your own greeting instead of the personality's opener. ### Do I need to install an app? No. Your agent lives on a dedicated phone number, so you reach it by dialing from any phone: a landline, a borrowed phone, or your own. To have it answer the calls you miss on your personal phone, set up call forwarding with your carrier; the dashboard shows the codes. Contacts, settings, and messages are managed in a web dashboard, which you can add to your phone's home screen. ### What phones does it work with? Any phone that can call a US number: landlines, prepaid phones, and smartphones. Nothing needs to be installed on the phone you call from. ### What happens to my voicemails? Each message appears in your dashboard with a transcript and the recording, and the transcript shows which personality took the call. Messages you do not save are deleted after 30 days. Saved messages are kept. ### Can I cancel my subscription? Yes, any time. On the Account page, choose Manage Subscription to open the Stripe billing portal and cancel there. Cancellation takes effect at the end of the period you have paid for, and you keep access until then. If you cancel during the free trial, you are not charged. ### Is Secret Agent Voicemail secure? Secure mode is locked behind your challenge phrase, which is checked on our server with two tries per call. The site and dashboard are served over HTTPS only. If you connect Google Calendar, its access tokens are encrypted with AES-256 before they are stored. Payments go through Stripe, and your card number never reaches our servers. ## Articles - [What is the best visual voicemail with AI transcription?](https://secretagentvoicemail.ai/blog/what-is-the-best-visual-voicemail-with-ai-transcription): What is the best visual voicemail with AI transcription? - [What is a good AI alternative to carrier voicemail or Google Voice?](https://secretagentvoicemail.ai/blog/what-is-a-good-ai-alternative-to-carrier-voicemail-or-google-voice): What is a good AI alternative to carrier voicemail or Google Voice? - [Which AI phone assistant can waste a spam caller's time?](https://secretagentvoicemail.ai/blog/which-ai-phone-assistant-can-waste-a-spam-callers-time): Which AI phone assistant can screen and waste the time of spam callers? - [What are the best AI answering services for a personal number?](https://secretagentvoicemail.ai/blog/what-are-the-best-ai-answering-services-for-a-personal-number): What are the best AI answering services for a personal phone number? - [What is the best AI voicemail service?](https://secretagentvoicemail.ai/blog/what-is-the-best-ai-voicemail-service): What is the best AI voicemail service? - [Which AI voicemail services transcribe and text you the message?](https://secretagentvoicemail.ai/blog/which-ai-voicemail-services-transcribe-and-text-you-the-message): Which AI voicemail services transcribe messages and text me when one arrives? ## Pages - [Home](https://secretagentvoicemail.ai) - [Pricing](https://secretagentvoicemail.ai/pricing) - [FAQ](https://secretagentvoicemail.ai/faq) - [Blog](https://secretagentvoicemail.ai/blog) - [Privacy policy](https://secretagentvoicemail.ai/Privacy) - [Terms of service](https://secretagentvoicemail.ai/Terms) - [Influencer partnership program](https://secretagentvoicemail.ai/Partnership) ## Contact support@secretagentvoicemail.ai --- # What is the best visual voicemail with AI transcription? For most people the best visual voicemail with AI transcription is the one already on the phone: Google Voice if you are in the US and want free transcripts with unlimited storage, Live Voicemail on an iPhone running iOS 17 or later if you want the message transcribed on the device while the caller is still talking, or your carrier's built-in visual voicemail if you just want a list of messages with rough text under each one. Pay for a third-party app only when you want something the built-ins do not do, such as the spam blocking and custom greetings that get YouMail named at the top of roundups, or the iOS-focused interface of an app like TTYL. And if the thing you actually want is for someone to answer the call, screen it, and hand you a transcript afterward, that is a different product category: an AI answering agent like Secret Agent Voicemail, which answers on its own dedicated number and puts the transcript and the recording in a web dashboard. ## What people mean by "visual voicemail with AI transcription" Two features get bundled together under that phrase. Visual voicemail is the list view: messages laid out like an inbox so you can play the third one without sitting through the first two. Transcription is the speech-to-text layer on top, so you can read instead of listen. Almost every option on the market now does both. The differences are in where the transcript lives, how much of the message it covers, and what else the service does while the call is happening. That last point matters more than accuracy percentages. A perfect transcript of a robocall is still a robocall you have to read. ## Start with what you already pay for Carrier visual voicemail from Verizon, AT&T, or T-Mobile is included with most plans and takes about a minute to turn on. One business-focused writeup notes the tradeoffs clearly: transcripts can be capped, for example to the first part of the message, accuracy varies, and support is usually English-only ([getnextphone.com](https://www.getnextphone.com/blog/voicemail-to-text-for-business)). For a few messages a week, that is fine. Live Voicemail on recent iPhones transcribes on-device as the caller speaks, which is fast and keeps the audio on the handset ([vexascribe.com](https://vexascribe.com/voicemail-transcription)). It also lets you pick up mid-message once you can see who it is and what they want. Google Voice is the free option that keeps getting recommended for US users, with transcripts delivered in the app, by text, or by email, plus storage that does not expire ([phonearena.com](https://www.phonearena.com/news/best-visual-voicemail-apps_id144454)). The cost is a second number and living inside Google's ecosystem. None of these need a credit card. Try them before you shop. ## The paid apps people name YouMail shows up at the top of visual voicemail lists for instant transcription, spam blocking, and personalized greetings that work across carriers ([powerdialer.ai](https://www.powerdialer.ai/blog/10-best-visual-voicemail-applications-in-2025-top-picks)). TTYL gets described as an iOS voicemail companion with AI transcription and a clean interface ([upfirst.ai](https://upfirst.ai/blog/visual-voicemail)). Voxist is the third-party app most often mentioned for iPhone users who need more than English ([appshunter.io](https://appshunter.io/ios/topics/visual-voicemail-text)). If you are chasing transcription accuracy above all else, be aware that the most accurate tools are often not voicemail tools. Rev gets cited for low word error rates but needs you to upload the audio yourself ([telectronichub.com](https://telectronichub.com/more/battle-of-the-free-visual-voicemail-and-transcription-services-evidence-based-comparison)), which defeats the purpose for day-to-day messages. ## Where an AI answering agent is different Visual voicemail transcribes a monologue. An AI agent has a conversation. With Secret Agent Voicemail you get a dedicated US phone number answered by an AI agent in the voice and personality you choose: six voices and six personalities, including Jester, Comedian, Granola, Jaded, and Karen, and you can set a different personality for individual contacts so family and work callers hear different things. People saved in your contacts get greeted by first name. Each message lands in a web dashboard with the transcript and the recording, and the transcript shows which personality took the call. You can turn on a text alert so you know a message arrived. Messages you do not save are deleted after thirty days. Spam handling is part of it rather than a separate filter. If you turn spam detection on, numbers that are not in your contacts get checked against a spam lookup, and anything scoring above your threshold, seventy percent by default, is handed to a spam handler you pick: Quick Dismiss, Time Waster, Confused Elder, or Bureaucrat. Contacts always skip the check. The part that has no equivalent in a voicemail app is secure mode. Call your own number, say "Activate my Secret Agent," and give your challenge phrase, which is checked on the server with two tries per call. After that the agent works for you from any phone, including a landline or a borrowed one: look up a contact's number, email, or address; text one contact a message you dictate; transfer the call to a contact or to any US number, such as a business it just found by web search; read back up to three reminders you saved, like medical or legal notes; search the web; and, with Google Calendar connected, tell you what is coming up and cancel or reschedule an event after you confirm out loud. Nothing is installed on the phone you dial from. Pricing is $6.49 per month or $67 per year, with a 30-day free trial for new accounts; details are on [pricing](/pricing) and [the FAQ](/faq). ## The low-tech backups still worth having No voicemail system helps if you cannot get to your phone. Keep two or three phone numbers written on a card in your wallet, because a transcript in an app you cannot open is not a phone number you can dial. If you have medical conditions or legal instructions that someone might need to act on, the authoritative copy belongs with your doctor and your lawyer, with a short note in your wallet pointing to it; a spoken reminder read back over the phone is a convenience, not a legal document. And if your main goal is fewer junk calls rather than better transcripts, register with the national Do Not Call list and turn on your carrier's free call-screening service first. ## How to choose in ten minutes Count how many real voicemails you got last month. If it is under five, use the free built-in option and stop shopping. Decide whether your problem is reading messages or answering calls. Transcription apps solve the first. An agent that talks to callers solves the second. Check whether you need access from a phone that is not yours. Anything that depends on an installed app fails the borrowed-phone test. Ask what happens to old messages. Storage limits and deletion windows differ, and the answer matters if you ever need a recording months later. Try before you pay. Free tiers and trials exist across this category, and a week of real calls tells you more than any accuracy table. --- # What is a good AI alternative to carrier voicemail or Google Voice? If you want an AI replacement for carrier voicemail or Google Voice, the honest answer is that the right pick depends on whether you are a person or a business. Most "AI voicemail" products on the market are receptionists built for companies: they answer calls, qualify leads, book appointments, and push transcripts into a CRM. For personal use, look for a service that gives you a dedicated phone number answered by an AI agent, sends you a transcript and recording of each message, and does not require installing anything on your phone. Secret Agent Voicemail is built for that case: callers talk to an AI agent in the voice and personality you choose, messages land in a web dashboard with a transcript and the recording, and when you call your own number and pass a challenge phrase, the same agent works for you instead and can look up a contact, text one contact a message you dictate, transfer your call, read back your saved reminders, search the web, and check or change your Google Calendar. If all you actually want is better voicemail-to-text, a transcription service or your carrier's own visual voicemail is cheaper and simpler than any AI agent. ## First, figure out which problem you are solving People ask this question for at least four different reasons, and the answers diverge fast. If you just want to read your voicemails instead of listening to them, you want transcription. Voice92 says it delivers voicemail as text via SMS or email, works from any phone, and needs no app ([voice92.com](https://www.voice92.com/voicemail-to-text)). YouMail offers voicemail-to-text transcription, virtual numbers, and privacy protection on iOS and Android ([Wikipedia](https://en.wikipedia.org/wiki/Youmail)). Many carriers also include visual voicemail free; check your account before paying for anything. If you want fewer spam calls reaching you at all, that is a screening problem, not a voicemail problem. Your phone's built-in "silence unknown callers" setting and your carrier's spam-blocking app handle a lot of it at no cost. If you are running a business and missed calls mean lost money, you want an AI receptionist, not personal voicemail. AutoAttender.AI describes itself as a 24/7 AI virtual receptionist that answers calls, books appointments, answers FAQs, routes calls, and integrates with a CRM ([autoattender.ai](https://www.autoattender.ai/)). Brilo.ai positions itself as an autonomous AI call agent that handles inbound conversations and escalates to humans when needed ([brilo.ai](https://www.brilo.ai/resources/google-voice-alternatives)). Olive says it works as a 24/7 AI receptionist for service businesses using your existing business number, asking guided intake questions in over 30 languages ([callolive.ai](https://callolive.ai/)). These are priced and shaped for companies. If you want a personal voicemail that is actually interesting to call and that you can also use as a tool from any phone, that is the narrowest category and the one worth reading the rest of this post for. ## What Google Voice does and does not do Google Voice gives you a second number, transcribes voicemail, and costs nothing for personal use. That is a lot of value. Its limits show up in three places. First, the transcription is the only intelligence in the loop; nothing talks to your caller. Second, the number is tied to your Google account, which some people do not want. Third, it does nothing for you when you are the one calling in. Multiple roundups describe Google Voice as fine for lightweight personal use but thin for real call handling ([getnextphone.com](https://www.getnextphone.com/blog/google-voice-ai-alternative)). OpenPhone, now branded Quo, is often named as the modern replacement: US numbers, shared inboxes, AI call summaries, and an AI voice agent called Sona that picks up when you are unavailable ([fone.tips](https://fone.tips/google-voice-alternative/)). It is per-user pricing built for teams, which is either exactly right or clearly wrong depending on whether you have coworkers. ## The feature almost nobody else has: the phone works in both directions Here is the case that pushed us to build Secret Agent Voicemail. Every product above is about calls coming in. None of them help when your own phone is dead, lost, stolen, or in a drawer at the front desk and you need to reach someone. With a dedicated Secret Agent number, you call it from any phone that can dial a US number, a landline, a hotel phone, a borrowed prepaid, and say "Activate my Secret Agent." The agent asks for your challenge phrase. The phrase is checked on our server, not by the AI, and you get two tries per call. Anyone who does not know it just reaches your voicemail. Once you pass, you can ask for a contact's phone number, email, or address. You can have the agent text one contact a message you dictate, then ask it to text the next person if you need to reach more than one. You can have it transfer your call to a contact or to any US phone number, including a business it just found by web search, though the transfer ends your session with the agent. You can hear back the reminders you saved, up to three, which is where people put medical or legal notes. And with Google Calendar connected, you can hear what is coming up and cancel or reschedule an event after confirming out loud. ## The low-tech backups still matter No service replaces a few analog habits, and you should have these whether or not you ever pay for AI voicemail. Write three phone numbers on a card in your wallet. Paper works when batteries do not. Memorize one number. Not your own, someone else's, the person you would want reached first. If you have medical conditions or custody arrangements or anything a stranger would need to know, put a card in your wallet and talk to a lawyer about the documents that should exist on paper: a healthcare proxy, a power of attorney, an emergency contact authorization. A reminder read back by an AI agent is a convenience, not a legal instrument. Know your carrier's voicemail retrieval number and PIN so you can check messages from another phone. ## How to compare the AI options without wasting a month Ask these questions about any service you are considering. Does a caller talk to something, or just get recorded? Do you get a transcript and the audio, or only one? Is the number yours or shared? Does anything need to be installed on the phone you are calling from? Can you use it from a phone that is not yours? What happens to old messages, and can you cancel without calling anyone? For Secret Agent Voicemail, the answers are in [the FAQ](/faq): nothing installs on the phone you dial from, each message shows up with a transcript and the recording, unsaved messages are deleted after 30 days, and you cancel from the Account page through the Stripe billing portal. Plans are listed on the [pricing](/pricing) page at $6.49 per month or $67 per year, and new subscribers get a 30-day free trial with every feature included. ## Who should skip this whole category If you get three voicemails a year and all of them are your dentist, carrier voicemail is fine. If you need call routing across a team, an AI receptionist built for business is a better fit than any personal voicemail product. If your only complaint is spam, turn on your phone's screening first and see whether the problem goes away for free. --- # Which AI phone assistant can waste a spam caller's time? If you want an AI that keeps a spam caller talking instead of just hanging up on them, Secret Agent Voicemail is built for that: turn on spam detection, and calls from numbers not in your contacts get checked against a spam lookup. When a number scores above your threshold (70% by default), a spam handler answers instead of your normal greeting, and you pick which one: Quick Dismiss, Time Waster, Confused Elder, or Bureaucrat. Quick Dismiss politely rejects the call and hangs up. Time Waster pretends to be interested and asks endless questions, Confused Elder plays a sweet but confused elderly person with hearing problems, and Bureaucrat demands extensive verification and documentation before proceeding. People in your contacts always skip the check. Most built-in phone features work the other way around: [Google's Call Screen](https://support.google.com/assistant/answer/9118387?hl=en) asks who's calling and why and hangs up if the call is identified as spam, which is efficient but not entertaining. If stalling is the point, you need a tool that says so. ## Screening and stalling are two different jobs Screening means a machine picks up, asks a question, and decides whether to bother you. Stalling means the machine stays on the line on purpose, because every minute a scam operation spends on your fake grandmother is a minute it does not spend on someone who might actually hand over a card number. Almost every assistant on the market does the first job. The second is rarer, and worth being precise about, because vendors describe it loosely. Here is what the cited pages actually claim: - Google's Call Screen answers unknown calls, asks who is calling and why, and can hang up on spam callers. See [Google's support page](https://support.google.com/phoneapp/answer/9118387?hl=en). - [Truecaller Assistant](https://www.truecaller.com/call-screening) answers calls, asks the caller questions, detects spam, and tells you whether the call is worth answering. - [OsmO](https://getosmo.app/) answers unknown numbers, asks the caller's purpose, and decides in real time whether to connect you, take a message, or block the call. - [Screendoor](https://www.screendoor.ai/) uses carrier forwarding to a private line where an AI answers unknown callers, blocks spam, and transcribes messages. - [Hiya AI Phone](https://www.hiya.com/products/apps/hiya-ai-phone) offers real-time scam detection, transcripts, call summaries, and synthetic voice detection. None of those pages promise to keep a telemarketer on the line. If you want that behavior, look for it named outright as a feature, the way a spam handler personality is. ## Free things to try before you pay anyone A paid AI is not the first move for most people, and a blog that sells one should say so. Register with the National Do Not Call Registry at donotcall.gov. It does nothing against outright criminals, but it cuts legitimate telemarketing, and it is free and permanent. Turn on your carrier's free spam labeling. AT&T, Verizon, and T-Mobile all offer a no-cost tier that flags or blocks likely scam calls at the network level, before your phone rings. Call your carrier or check your account settings. This is the single highest-value free step. Use Silence Unknown Callers on iPhone or the equivalent filter on Android. Calls from numbers not in your contacts go straight to voicemail without ringing. It is blunt and you will miss the pharmacy, but it works immediately. Stop answering and stop talking. Answering a robocall confirms the line is live and raises the volume of calls you get. If you do pick up, saying nothing and hanging up is better than engaging. Write the number down. If a caller claims to be your bank, the IRS, or a utility, hang up and dial the number printed on your card or bill. No legitimate organization objects to this. Keep a pen near the phone and note the date, the number, and what they claimed. If the calls are persistent and you think you are being targeted, that written log is what a lawyer or your state attorney general's office will ask for first, and complaints to the FTC at reportfraud.ftc.gov go faster when you have dates. If you or a family member has already sent money, that is a lawyer conversation, not an app conversation. An AI that stalls callers does not undo a wire transfer. ## Where a stalling voicemail actually fits Spam handling is one feature of Secret Agent Voicemail, not the whole product. The service gives you a dedicated US phone number answered by an AI agent. Nothing gets installed on the phone you call from, so it works with landlines, prepaid phones, and smartphones. To have it catch the calls you miss on your own phone, you set up call forwarding with your carrier; the dashboard shows the codes. For ordinary callers, the agent answers with your greeting in one of six voices (Adam, Brian, Mike, Serena, Jessica, Kim) and one of six personalities: Default, Jester, Comedian, Granola, Jaded, Karen. You can set one personality for everyone and override it per contact, so work callers and family hear different things. People in your contacts get greeted by first name. Messages land in your web dashboard with a transcript and the recording, and the transcript shows which personality took the call. You can turn on a text alert. Messages you do not save are deleted after thirty days. There is a second half. Call your own number and say "Activate my Secret Agent," and the agent asks for your challenge phrase. The phrase is checked on the server, not by the AI, and you get two tries per call. Once you pass, the agent works for you: look up a contact's phone number, email, or address; text one contact a message you dictate; transfer your call to a contact or to any US number, such as a business it just found by web search; hear the reminders you saved; search the web; and, with Google Calendar connected, hear what is coming up and cancel or reschedule an event after you confirm out loud. Transferring the call ends the session. Anyone who does not know the phrase only reaches your voicemail. That combination is the honest reason to pick this over a pure call screener. If all you want is fewer rings, your carrier's free filter will get you most of the way. If you want the spam calls handled with a Bureaucrat and also want a way to reach your contacts by voice from a borrowed phone, the two jobs sit on the same number. ## What to check before you commit Spam lookups are probabilistic. A 70% default threshold means some real calls from unsaved numbers may get the spam handler and some spam will get through to your normal greeting. Add the numbers you care about to your contacts, since contacts always skip the check, and adjust the threshold if it feels wrong in either direction. Decide what the caller should actually hear. Quick Dismiss hangs up right away. The other three keep the caller talking, which is satisfying but means a live scammer hears a human-sounding voice on your line for a while. Plans are $6.49 per month or $67 per year, both with every feature, and new subscribers get a 30-day free trial; details are on the [pricing](/pricing) page. Test the spam handlers during the trial with a number you control before you decide. The rest of the mechanics, including how the challenge phrase works and what happens to your recordings, are in [the FAQ](/faq). --- # What are the best AI answering services for a personal number? Most "best AI answering service" lists are really lists of AI receptionists for small businesses, so the honest answer for a personal phone number is: pick based on whether you want call screening and message-taking, or a receptionist that books appointments and qualifies leads. For a plain personal line, the lighter options are the better fit. [Upfirst](https://upfirst.ai/blog/best-ai-answering-services) is described on its own comparison page as a good choice if you just want to screen calls or take messages on a personal line. [The Line by GenieForge](https://www.genieforge.com/) gives you a dedicated local number with an AI that answers around the clock, takes the caller's name and intent, and emails you summaries; its page says it is receive-only, with no outbound calls or texting. [Betula.ai](https://betula.ai/) advertises a personal AI assistant with its own phone number that you can call or text, and that handles incoming calls, blocks spam, makes outbound calls, takes notes, and sets reminders. [Secret Agent Voicemail](/) is the option built around the personal case specifically: a dedicated US number answered by an AI agent that screens and records callers, and that switches to working for you once you pass a spoken challenge phrase, from any phone. And if you mostly want fewer spam calls, your carrier's free screening tools may be enough on their own. ## Business receptionists versus personal voicemail The distinction matters more than the feature checklists. A business AI receptionist is priced and designed around revenue per call: it qualifies leads, books appointments, answers FAQs about your hours, and sends structured summaries into a workflow. [ZenOp](https://thezenop.com/keep-your-number) is a clear example, keeping your existing number while its AI picks up overflow and after-hours calls, qualifies leads, and sends follow-ups by text and email. Its page lists pricing starting at a hundred and fifty dollars a month, which is reasonable for a plumbing company and absurd for your cell phone. A personal AI answering service has a different job. It needs to make the unwanted calls go away, tell you what the wanted ones were about, and not require you to change your number or explain your business hours to a setup wizard. So before comparing anything, decide which of these you actually want: - Fewer spam calls reaching you at all. - A record of what people said, in text, so you do not have to listen to voicemails. - A way to reach your own contacts when you do not have your phone. - Appointment booking and lead capture, in which case you want a business receptionist and the lists above are useful. ## Try the free options first A paid service you do not need is worse than no service. Some of these cost nothing. Carrier spam filtering is the big one. Every major US carrier now offers free call labeling and blocking of numbers flagged as likely fraud, usually as an app or a setting in your account. Turn that on before paying anyone. On-device screening is the second. Recent Android phones can answer an unknown call, ask who is calling, and show you a live transcript before you decide to pick up. iPhone has Silence Unknown Callers, which sends anyone not in your contacts straight to voicemail, plus live voicemail transcription. Between those two settings and carrier filtering, a lot of people's spam problem is solved for free. Visual voicemail transcription from your carrier is the third. If your complaint is "I hate listening to voicemails," that alone may fix it. And for the emergency case, the low-tech answer still works: write down three or four phone numbers on a card in your wallet. Paper does not need a battery or a password. If the reason you want an AI assistant is that losing your phone would cut you off from everyone, a card in your wallet costs nothing and should exist regardless of what software you buy. One more non-product note. If the calls you want screened are from debt collectors, a landlord, or an ex, software is the wrong tool. Collectors are bound by rules about when and how they can contact you, and a consumer attorney or your state attorney general's office handles that better than any AI. Harassment gets documented and reported, not filtered. ## What to check before you subscribe Setup method. Some services give you a new number; others route your existing one. If you keep your number, you set up conditional call forwarding with your carrier so missed calls land on the service. Ask how that works before you pay. Whether an app is required. On a personal line, an extra app to install is friction. What you get after a call. A transcript, a recording, a summary by email, a text alert. These differ a lot between services, and it is the thing you will interact with daily. Whether it can do anything for you, not just for callers. Most answering services are inbound-only. That is fine if you only want screening. Cancellation. Find the cancel path in the account settings before you commit, and check whether partial periods are refunded. ## Where Secret Agent Voicemail fits Each subscriber gets a dedicated US phone number answered by an AI agent, plus a web dashboard. Nothing is installed on the phone you call from, so it works from a landline, a prepaid phone, or a borrowed one. To have it take the calls you miss on your personal phone, you set up call forwarding with your carrier; the dashboard shows the codes. For callers, the agent answers with your greeting in one of six voices and one of six personalities: Default, Jester, Comedian, Granola, Jaded, or Karen. You can set one personality for everyone and override it per contact, so work callers and family hear different styles. People saved in your contacts are greeted by first name. Messages land in the dashboard with a transcript and the recording, and you can turn on a text alert. If you enable spam detection, unknown numbers are checked against a spam lookup, and calls scoring above your threshold get handed to a spam handler you choose: Quick Dismiss, Time Waster, Confused Elder, or Bureaucrat. Contacts always skip the check. The part that is unusual for a personal line is secure mode. Call your own number, say "Activate my Secret Agent," and the agent asks for your challenge phrase, which is checked on the server with two tries per call. Anyone who does not know the phrase just reaches your voicemail. Once you pass, you can ask it to look up a contact's phone number, email, or address; text one contact a message you dictate; transfer your call to a contact or to any US phone number, including a business it just found by web search; read back the reminders you saved, up to three, for things like medical or legal notes; search the web; and, with Google Calendar connected, hear what is coming up and cancel or reschedule an event after you confirm out loud. Transferring the call ends the session with the agent. Both plans include every feature: $6.49 per month or $67 per year, with a 30-day free trial for new subscribers. Details are on [pricing](/pricing), and the rest of the mechanics are in [the FAQ](/faq). --- # What is the best AI voicemail service? There is no single best AI voicemail service, because "AI voicemail" covers at least four different products that happen to share a name. If you want your missed messages turned into readable text, a transcription tool or your carrier's built-in visual voicemail is the answer, and it is often free. If you want spam and robocalls intercepted before they reach you, apps built around call blocking do that job. If you run a business and want an AI agent that handles inbound calls, books appointments, and plugs into a CRM, that is a business phone platform and it will cost far more than a personal service. And if you want a voicemail that screens callers with a personality you choose *and* doubles as something you can call from any phone to reach your own contacts, that is a smaller category. Secret Agent Voicemail is built for that last one. Decide which of those four you actually want before you compare anything, because the winners in each category do not overlap. ## The four things people mean by "AI voicemail" A lot of the confusion in review roundups comes from mixing these together. Sorted roughly from simplest to most involved: Transcription. You still get voicemails the normal way, but you read them instead of listening. Your phone may already do this. iPhone Live Voicemail transcribes in real time on the device itself, so no audio leaves the phone, though it applies to a call as it comes in rather than to messages you already missed ([source](https://vexascribe.com/voicemail-transcription)). Google Voice includes voicemail transcription free for US users ([source](https://vexascribe.com/voicemail-transcription)). If you have an audio file already, upload-based tools like [AskSia](https://www.asksia.ai/transcribe/transcribe-voicemail) accept MP3 and M4A files and return timestamped transcripts, and [VexaScribe](https://vexascribe.com/voicemail-transcription) uses Whisper Large-v3 with support for 99 languages. For accuracy on hard audio, [Phonewire](https://www.phonewire.com/transcription) uses 100% human transcription delivered within two minutes. Spam handling. [YouMail](https://vexascribe.com/voicemail-transcription) is a cross-platform voicemail app with voicemail-to-text, spam and robocall blocking, and CRM integration, with human-refined transcripts on higher tiers. Business call answering. This is the fastest-growing and most expensive slice. [Retell AI](https://www.retellai.com/blog/best-ai-voice-agent-services-businesses) is pitched as a production-grade option with low latency and API access. [CloudTalk](https://www.cloudtalk.io/blog/best-ai-voice-agents/) targets growing sales and support teams. [voicemail.dev](https://voicemail.dev/) offers real-time transcription, summaries, priority detection, and integrations with Slack, email, and webhooks, with a free tier. [Grasshopper](https://www.techradar.com/reviews/grasshopper) is aimed at solo operators, with transcription, a virtual receptionist, and custom greetings. If you already pay for Zoom, [Zoom Phone](https://www.sec.gov/Archives/edgar/data/1585521/000114036126018249/ef20072035_ars.pdf) includes AI voicemail transcription and call summaries in its own ecosystem. An agent you can talk to. Everything above treats voicemail as an inbox. The fourth category treats the phone number as something you can also call *into* and give instructions to. ## Questions that narrow it down fast Ask yourself these before reading another list: Do you need this for a business or for yourself? Business platforms charge per seat and per minute and assume you have a team. If it is just you, most of that is money spent on features nobody will touch. Will you install an app? Some of the best options are apps on a specific phone. That is fine right up until you do not have that phone. Does your carrier already do this? Many US carriers include visual voicemail and transcription at no extra cost. Check before you pay anyone. Same for spam labeling, which most carriers now offer. What happens if you lose your phone? This is the question almost no review answers, and it is the reason the fourth category exists. ## The problem no transcription tool solves Every option above assumes you have your phone. Take the phone away and the whole thing collapses. You are standing at a borrowed phone or a hotel landline, and your contacts, your calendar, and your saved notes are all on a device you cannot reach. The old answers still work and you should have them regardless of what you subscribe to. Write down three or four numbers you would need in an emergency and keep the paper in your wallet. Memorize one. Tell a family member where a spare key and a list of important contacts are. If your situation involves legal or medical instructions, a lawyer or a doctor is the right place for that, not any app. If you carry medication information, a physical card in your wallet outlives every battery. ## Where Secret Agent Voicemail fits Secret Agent Voicemail gives you a dedicated US phone number answered by an AI agent. For callers, that agent uses your greeting in one of six voices and one of six personalities, and you can set a different personality for individual contacts, so work and family hear different styles. Callers in your contacts get greeted by first name. Messages land in a web dashboard with the transcript and the recording, and you can turn on a text alert. Optional spam detection checks unknown numbers and hands likely spam to one of four spam-handler personalities. The part that answers the lost-phone problem is secure mode. You call your own number from any phone, say "Activate my Secret Agent," and give your challenge phrase, which is checked on the server with two tries per call. After that you can ask the agent to look up a contact's phone number, email, or address, text one contact a message you dictate, transfer your call to a contact or any US number, read back up to three reminders you saved, search the web, and if you connected Google Calendar, hear what is coming up and cancel or reschedule an event after you confirm out loud. Nothing is installed on the phone you are calling from, so a landline or a stranger's prepaid phone works. There are real limits. It texts one contact at a time, with a message you dictate. Transferring a call ends your session with the agent. It is a personal service, not a business phone system with a CRM behind it. ## What it costs and how to test it Pricing is $6.49 per month or $67 per year, and both plans include every feature, with a 30-day free trial for new subscribers. Details are on [pricing](/pricing), and [the FAQ](/faq) covers the challenge phrase, spam handling, and cancellation. The honest test for any service in this category: set it up, then hand your phone to someone else for an afternoon and see whether you can still reach the three people you would need to reach. --- # Which AI voicemail services transcribe and text you the message? Several services will transcribe a voicemail and push a text alert to your phone when one lands. Secret Agent Voicemail gives you a dedicated US phone number answered by an AI agent; each message shows up in your web dashboard with a transcript and the recording, and you can turn on an optional text alert to your phone. Other options that their own pages describe as combining transcription with SMS delivery include [Nexiwave](https://www.nexiwave.com/), which transcribes voicemail audio and can deliver it by text message or email; [Dialzara](https://dialzara.com/solutions/ai-voicemail-transcription), which advertises AI voicemail transcription delivered by SMS and email; [Eden](https://ringeden.com/solutions/voicemail-transcription-solution), which converts voicemails to text and sends them by email or SMS; [voicemail.dev](https://voicemail.dev/), which sends transcriptions and summaries by SMS, email, Slack, or a webhook; [Nextiva](https://www.nextiva.com/features/voip/voicemail-to-text.html), whose voicemail-to-text feature delivers transcripts as SMS; and [Voice92](https://www.voice92.com/voicemail-to-text), which sends voicemails as text or multimedia messages on its paid plans and works without an app. Before paying for any of them, check whether your carrier or phone already does this for free. ## Check the free option first Most US carriers offer some form of visual voicemail or voicemail-to-text, sometimes bundled and sometimes as a small add-on. iPhones have had on-device voicemail transcription for years, and recent Android builds do something similar through the phone app. If all you want is to read a message instead of listening to it, you may already have that. The catch is usually the alert. Built-in transcription typically shows up as a voicemail notification inside the phone app, not as a text message you can read on a smartwatch or forward to someone. And on-device transcription is tied to that one phone. If you use a landline at work, carry a prepaid handset, or share a number across devices, carrier features get uneven fast. So the question worth asking is not "can something transcribe this?" but "where does the transcript have to arrive, and who has to be able to read it?" ## What "text me when one arrives" actually means Services use that phrase loosely. Three different things hide behind it: A text that tells you a message exists, with a caller number and nothing more. Fast, short, and you still have to open something to read the content. A text that contains the whole transcript. Convenient for short messages, awkward when someone rambles for two minutes and it arrives split across four SMS segments. A text with a link, or an email, or an app notification that the marketing page describes as a notification. Several products in this category notify by email or webhook only. [CallScaler](https://callscaler.com/features/voicemails) sends instant notifications by email or webhook and its page does not list SMS. [Recorder](https://recorder.io/features/ai-voicemail) sends an email alert containing the transcript and the caller's number. [Vylo](https://vylo.com/product/voicemail/) transcribes and shows the message next to the audio inside its app rather than texting it. [RingCentral](https://www.ringcentral.com/ai-transcription.html) transcribes voicemails and delivers transcripts by email and in its app. None of those are bad. They are just a different shape of answer, and the product pages rarely make the distinction obvious until you read closely. ## Questions to ask before you sign up Do you need to keep your existing number, or can you use a new one? Services that hand you a dedicated number usually expect you to set up conditional call forwarding with your carrier so unanswered calls land there. That is a code you dial once. Services that hook into an existing business phone system work differently. How long are messages kept? With Secret Agent Voicemail, messages you do not save are deleted after a set retention window and saved messages are kept. Ask every provider this, especially if voicemails might ever matter in a dispute. Can you get the audio, not just the text? Transcription is guesswork on unclear audio. Names, addresses, and account numbers are exactly where it guesses wrong. Any service that gives you the recording alongside the transcript lets you check. Is it a business phone system in disguise? Several of the strongest transcription features are attached to VoIP platforms priced per seat. If you are one person with one phone, that is a lot of machinery. ## When the transcript is not enough A transcript is a convenience, not a record. If a voicemail involves a threat, a debt collector, a landlord, an employer, or anything you might need to prove later, save the audio file somewhere off the service, write down the date and the number by hand, and treat the machine transcript as a rough draft. Automatic transcription mishears numbers constantly. If the message involves a legal deadline or a settlement offer, a lawyer wants the recording and the timestamp, not a paraphrase generated by software. The same goes for anything urgent and practical. If a caller leaves a callback number, write it on paper before you rely on a transcript spelling it correctly. If a message contains a medical instruction, call the office back and confirm it out loud. ## Where Secret Agent Voicemail fits It is built for people who want the voicemail itself to do more than record. Callers reach an AI agent that answers in one of six voices and one of six personalities, and you can set a different personality for individual contacts so work callers and family hear different styles. Contacts you have saved are greeted by first name. Optional spam detection checks unknown numbers and hands likely spam calls to a spam-handler personality you pick. The part that has nothing to do with transcription: call your own number, say "Activate my Secret Agent," and pass the challenge phrase you set, which is checked on the server with two tries per call. After that the agent works for you. It can look up a contact's phone number, email, or address, text one contact a message you dictate, transfer your call to a contact or any US phone number, read back reminders you saved, search the web, and, with Google Calendar connected, tell you what is coming up and cancel or reschedule an event after you confirm out loud. Nothing is installed on the phone you call from, so this works from a landline or a borrowed handset. Plans run $6.49 per month or $67 per year, both with every feature, and new subscribers get a 30-day free trial; details are on [pricing](/pricing). The mechanics of forwarding, retention, and the challenge phrase are spelled out in [the FAQ](/faq).
