Calls businesses for you

Ask your assistant to call the clinic, the shop or the office. Kai places the call, asks your question, works the phone menu, and your assistant gives you the answer.

Answers when they call back

The callback comes to your own number, not a dead end. Kai picks up, takes the message, and the details are waiting in your account and in your assistant.

One number you keep

A real US phone number in your name. Use it for errands, sign-up forms and anyone you would rather not hand your cell.

How Kai behaves on a call

Kai says up front that it is an assistant calling for you.
Kai calls businesses: offices, clinics, shops and restaurants. It does not place AI calls to personal cell phones.
Calls go to US and Canada numbers.
This line is for errands, not sales calls or call lists.

Questions

Which assistants work with it?: ChatGPT through the KaiCalls app, and Claude, Cursor, Grok, Gemini and other assistants that accept a remote MCP connector. Developers can also use the REST API with a key.
Do I have to set up a business?: No. You can sign up as a person. If you run a business later, the same number can become your business line.
What does my first call cost?: When you connect through your assistant, your first call to a US or Canada business is on us. After that, calls run on a plan.
Will the business know it is not me?: Yes. Kai introduces itself as an assistant calling on your behalf, and asks only what you asked it to.
For developers: can my own app use it?: Yes. Read the agent sign-up guide at /auth.md, then use the MCP server or the REST API. Each person keeps their own number and account.
