Grok Bot can now phone people and businesses for you: Elon Musk says it makes the request, takes notes and sends a call summary (0.77 prerelease)

Background

Having an assistant make phone calls is a common ask for personal agents: booking tables, rescheduling, checking orders, sitting in support queues. Until now Grok Bot users needed a third-party calling service for outbound calls (on Oct 18 Musk shared a user's restaurant-booking Bot built on the third-party ClawCall service). On Oct 25 SpaceXSI CEO Elon Musk posted: "Grok @Bot can now call someone or a business for you, make a request on your behalf, take notes on the response and send you a note summarizing the conversation!" (post)

How it works

Musk quoted a third-party rundown by @alexmichaelio of the Grok Bot 0.77 prerelease (post): the Bot dials, waits on hold, presses keys through phone menus and gets transferred while the user watches a live transcript; the same build showed a Messages on Mac setup screen (still switched off) and Tailscale private-network access. These are prerelease observations, not confirmed final features, and SpaceXSI has not said which voice model powers the calls.

Benchmarks

This is a product feature; no official benchmarks or call success rates were published. Public X metrics at capture showed Musk's post at about 14.4K likes, 1,399 reposts, 3,332 bookmarks and 2.31M views.

Getting started

Per CellCog and The Tech Signal, as of Oct 25 the official Grok Bot changelog on x.ai still listed v0.75.5 (Oct 23) as the latest release and the docs had no outbound-calling page; supported countries and numbers, plan requirements, call recording and AI disclosure to the callee are all unannounced. Once 0.77 reaches your client, tell the Bot who to call and what you need. For calls to third parties, mind local consent and disclosure rules for AI voices (in the US, the FCC ruled in 2024 that AI-generated voices fall under the TCPA).
