Grok Bot starts talking back on desktop and mobile

SpaceXAI said on September 17 that Grok Bot, its agent product, is getting a voice mode in both the desktop and mobile apps, in a post shared on Threads. The feature “will be rolling out gradually over the next couple of days,” the company wrote.

Grok Bot is not a chat assistant you can simply talk to. Each bot is a persistent agent running on its own dedicated cloud computer. It works through websites, applications and inboxes, carries out multi-step tasks end to end and comes back to the user when it needs an approval or a decision. RuntimeWire framed voice as a way to direct Grok Bot while it works across apps, and said it raises the stakes for approvals once a spoken command can trigger a real action.

Voice calls were already being tested by late August. The thread so far:

• August 11: Grok Bot opens in early beta for SuperGrok Heavy, Cursor Ultra and Cursor Premium Teams subscribers on macOS, Windows, Linux and iOS, with Android listed as coming soon, VentureBeat reported. Cursor Ultra costs $200 a month for individuals and Cursor Premium Teams $120 per seat per month.
• August 26: @blankspeaker posts a screenshot of a “Start a voice call” headset button in Grok Bot, as RuntimeWire reported.
• September 17: SpaceXAI announces voice mode for the desktop and mobile apps, rolling out gradually.

In the weeks between, access widened to three more paid plans: SuperGrok Plus, Cursor Pro+ and Cursor Teams. An Android build of the beta has also reached Google Play. SpaceXAI said Grok Bot grew out of an internal prototype used for sales outreach, marketing, operations and software development.

VentureBeat also noted that SpaceXAI released no benchmarks for Grok Bot on agentic tasks. It placed Grok Bot alongside Anthropic’s Claude Cowork and OpenAI’s Codex computer control, Workspace Agents and ChatGPT Work.

Later, on September 23, Elon Musk quote-posted a walkthrough from SpaceXAI’s Matt Palmer titled “here’s what’s new in Grok @Bot this week.” It covered voice calls, a 1Password vault, and inline forms and drafts for email and Slack. In the footage the bot places voice calls and records voice memos, TeslaNorth reported.
