An AI app that calls businesses for you

Name: call4me
Price: 0.25 USD

yes: call4me is an AI that calls businesses for you. ask ChatGPT, Claude or Codex to call a restaurant, a doctor's office, a repair shop or a customer service line, and call4me dials it, gets through the phone menu and the hold, talks to whoever answers, and brings back what they said with a transcript. if they want you on the line, it rings your phone. calls cost $0.25/min from pickup and half that on hold, and unanswered calls are free.

there is no separate call4me phone app. in ChatGPT it is a plugin you install and sign in to, and in Claude, Codex and other assistants it connects over MCP. so the assistant you already ask for help looks up the business, places the call, and answers the caller's questions while the call is still going.

the calls are real and published: below are recorded calls that booked a dinner table, moved a dentist appointment, got a junk removal quote and booked the pickup, and took a Spectrum internet bill from $85 to $55 a month for a year. we have also called the customer service lines of 81 companies and published the recordings.

How the call works

tell your assistant what you need in plain words, like "move my thursday 3:30 dentist appointment to friday after 3."
call4me checks it has everything that kind of call needs, and your assistant asks you for anything missing in one message.
it calls the business from your call4me number, gets through the phone menu and the hold, and talks to whoever answers.
if the business asks something only you know, the question comes back to your assistant mid-call. if they want the account holder, your phone rings and you join.
you get the outcome and the full transcript, and the recording is in your account.

if you hate calling businesses, this is the part you hand off: the menu, the hold and the conversation. you can still listen in without anyone hearing you, and press 1 anytime to take over.

the caller calls for you and never claims to be you, and it never reads out card numbers, bank details or passwords. it makes the calls a person would make for their own errands: bookings, appointments, quotes and questions for a business, not sales or telemarketing.

calls go out from a free US number, assigned on your first call, to businesses in the US, Canada, Europe, the UAE and Japan.

Other apps that call businesses for you

Gemini Call for Me: Google's Gemini app can get business hours, product availability and quotes, book or manage appointments and reservations, and navigate phone menus and wait on hold. it needs a Pixel 11 with a US SIM card, a Google AI subscription, the Phone by Google public beta and English as the device language. it calls US numbers only, from your own phone number, and you can follow a live transcript or live audio and take over. Google is rolling it out gradually.
Google Search calling: AI Mode calls businesses for information they don't list online, like the earliest appointment or what is in stock, and only for what you asked. it is available in English to signed-in users over 18, and call results can take up to 30 minutes, in your AI Mode history or by email.
Callio: an iPhone and Android app that calls US businesses you pick, often shared from Google Maps, for reservations, availability, hours and prices. you approve what it will ask, and the answer comes back with a transcript afterward.

if you have a Pixel 11 and a Google AI subscription and the call is to a US business, try Gemini first. call4me fits when you already use ChatGPT, Claude or Codex, want to call from any phone or computer, want to join or listen live, or need to call outside the US. more apps that call for you, compared from their own pages, are in AI apps that make phone calls for you.

Real calls call4me made

recorded calls, each with what was asked, what happened and a transcript:

book a table for two (TAO Los Angeles): the restaurant confirmed a reservation for two at 8 pm.
reschedule a dentist appointment (a dental office): the office moved the appointment to monday at noon with the same dentist, and confirmed it on the call.
get a junk removal quote and book the pickup (A1 Hauling, San Francisco): the hauler quoted about $140 and booked the pickup for 11 am the next day. it read the street number back wrong, and the agent agreed by mistake. a second call fixed the address.
get a wheel alignment quote without waiting on hold (Wheel Works, Franklin Street, San Francisco): after waiting on hold, the agent got a $129.99 starting quote for standard alignment and about $210 for the lifetime option. staff said they check the suspension, accept walk ins and usually need one to two hours. this was a general quote, with no vehicle specified or service booked. taxes and extra repairs were not priced. the written standard warranty is limited to 12 months or 12,000 miles.
call spectrum retention to lower an internet bill (Spectrum): saying 'cancel' and then 'disconnect' reached a customer solutions rep after about 5 minutes on hold. he wouldn't change the account for an assistant, so the caller patched in the user, who got $55 a month for a year instead of $85. that part of the call is not published.
transfer a prescription to another pharmacy (Amazon Pharmacy): the phone menu said it doesn't process transfer-out requests and routed the call to a representative, who transferred the prescription out to the walgreens and canceled the pending amazon fill. no confirmation number was given.

paste the setup prompt below into your assistant. the install page has the steps for Claude Code, Codex, Claude Desktop, claude.ai, ChatGPT and other apps.
ask for the call in plain words, and it asks you for anything missing before it dials.

I read https://call4.me/app-that-calls-businesses-for-you. Make that phone call for me with call4me.

If you don't have the call4me tools (call4me_*) yet, add the call4me MCP server first and sign me in:
   - Claude Code:  claude mcp add --scope user --transport http call4me https://call4.me/mcp  (then I run /mcp, pick call4me, and choose authenticate)
   - Codex:        codex mcp add call4me --url https://call4.me/mcp  then  codex mcp login call4me
   - ChatGPT: you can't install plugins from the chat, so give me this link to install the call4me plugin, then I sign in: https://chatgpt.com/plugins/plugin_asdk_app_6abdec89d46c81919cda058ca9f62cb8
   - Claude Desktop or claude.ai: add a custom connector with the URL https://call4.me/mcp and sign in when it asks.
   - Muse: build a custom integration to the call4me remote MCP server at https://call4.me/mcp (streamable HTTP) with the official MCP SDK. Ask me for my call4me API key (it's at https://call4.me/account) through your secure credential flow, never in chat, store it in your Secure Credentials Store, and send it as Authorization: Bearer <key>. List the tools, test call4me_get_balance, and save it as a reusable skill.
   - Grok Bot: add a custom MCP server called call4me (remote HTTPS, no headers, no auth) at my personal server URL, which I copy from https://call4.me/account. You add it from this chat; no separate approval is needed. If you offer sign-in instead, use https://call4.me/mcp and I sign in.
   - grok.com: you can't add connectors from the chat, so I do it: grok.com/connectors, New Connector, Custom, with the URL https://call4.me/mcp, then I sign in.
   - If you can't sign me in, I copy my personal server URL from https://call4.me/account and you use that instead.
   I sign in with Google or X.

1. Ask me which business to call, what I need from them, and what you may agree to for me.
2. Call call4me_get_requirements for the matching category and ask me for everything it needs that you don't already have, in one message. Find the business's number (web search if needed) and check it's the right location.
3. If I want to join when a person picks up or just listen in, pass connect_when or listen_in, and tell me first which call4me number will ring me.
4. Place the call with call4me_place_call, show me the calling_number it returns, then keep calling call4me_get_call with wait_seconds until it finishes. Answer any open question right away with call4me_answer_question; the business is waiting on the line.
5. Tell me the result in one or two lines.
