For ChatGPT

ChatGPT can't make calls. Give it a phone.

ChatGPT can look things up, write your email, and plan the week. It cannot ring the tyre place and ask what a set of four costs fitted. CosVoice is the phone it is missing: a real number in your area code that it can call from, answer on, and report back through.

Get a line

Pick a number in your area code. About a minute, and you can try it for $3 once.

Add the connector

In ChatGPT, add https://cosvoice.com/mcp as a connector. A CosVoice page opens, you sign in and press Allow. There is no key to paste.

Ask for a call

Say what you want in a sentence, including what to accept if the first answer is no. ChatGPT asks the line; the line does the talking.

Things to ask ChatGPT for

Plain sentences. The line works out the conversation.

Call Osteria Mozza and get a table for two on Friday at 7:30. Take 7:00 to 8:30 if that's gone.

Ring the dentist and move my Thursday cleaning to an afternoon next week.

Call the pharmacy and find out whether the refill is ready and what it costs.

Phone the landlord about the leak, and tell me what they said.

Calls take minutes, not seconds

ChatGPT gets an id straight away and the write-up when the call ends. Ask it to check back, or let CosVoice wake it when the call is done.

It works in the other direction too

The person your line rang can ring back and reach the same assistant, with your standing instructions already in place.

Your other assistants can share it

The same line connects to Claude, Cursor, or a Grok Bot. Connect whichever you happen to be using.

Common questions
Does ChatGPT do the talking?

No. ChatGPT writes the brief; the CosVoice line holds the conversation in a natural voice, then hands back the outcome, the details, and the transcript.

Do I need the paid ChatGPT plan?

You need a version of ChatGPT that supports connectors. If yours does not, you can still place calls from your CosVoice dashboard and read the write-ups there.

Does the call cost extra?

No. Calls use your CosVoice plan's minutes, whichever assistant asked for them. Try it for $3 once: a number and 10 minutes of calls to use over 14 days.

Can it spend my money on a call?

No. The line never reads out a card number or agrees to a charge, so the most it commits you to is a booking or an appointment.

Also for Grok Bot, Meta's Muse, and anything you write yourself.

Give your Chief of Staff a phone.

Pick a number, save the contact, make the first call. About a minute.
