xAI is preparing to promote its Voice Agent Builder on Grok, allowing users to build custom agents that can answer their phone calls.

Let Grok answer your phone

I’ll help you deploy your first agent in just a few minutes without a single line of code.

Create an AI that picks up your calls and talks in a natural voice. Tell it what to handle — questions, bookings, messages — and we'll give you a free number so it can start taking real calls in minutes.

That would be interesting 👀
