During a 72-hour hackathon, a participant in a speech-restoration study used a Neuralink brain implant to control a computer and communicate without speaking.

The prototype detects intent from neural signals. Thinking “Hey Neuralink” starts Grok as an AI agent that can perform computer actions.

It can also detect attempted speech, removing the button needed to start or stop recognition. Engineers tested real-time brain-activity visuals and Bloom, Neuralink’s communication app. These are early prototypes, not ready user features.
