3rd Place: ThinkVoice lets you speak without moving your mouth by combining Grok Voice with brain-sensing technology.

It understands the conversation, suggests what you might want to say next, and lets you select a response using subtle motor movements.

SpaceXAI (@SpaceXAI) — Wed, 15 Jul 2026 20:44:30 GMT

In response to user questions about privacy: Since launch, Grok Build has fully respected zero data retention (ZDR). All users have always had the ability to disable data upload in the CLI.

When data upload was disabled, this choice was respected. In the early beta, data retention was enabled by default for non-ZDR users. Based on your feedback, we changed this. We are now going further to protect privacy.

With all retained data deleted, retention default off, and an open-source harness, we are offering complete user privacy. You can also run Grok Build fully open-sourced and local-first with your own inference.

We disabled default retention for all Grok Build users starting on July 12th. Additionally, we are deleting all coding data that was previously retained, ensuring every user’s preferences are respected. With these steps, Grok Build goes beyond other major coding products to protect user privacy.

If ZDR is disabled, the /privacy command is available in the CLI to disable data retention, which also deletes previously synced data.

Run the /privacy command to view or change your settings at any time.
