## What is TethrX?

TethrX is a native, private, independent remote for Grok Build, SpaceXAI's terminal coding agent. Your phone is only a control plane, Grok, its tools, and your code stay on your own machine. TethrX connects to a small open-source bridge you run on your computer.

• Watch Grok work in real time — thoughts, commands, file edits, and their output.
• Approve or reject every tool call — from the app, or straight from a push notification on your lock screen.
• Plan mode — Grok drafts a plan; you review and approve it before it builds.
• Review what changed — per-file diffs, commit or discard from your phone.
• Queue follow-ups, branch sessions, schedule recurring tasks, dictate messages.
• No accounts, no tracking, no third-party servers. Your phone talks only to your bridge, direct, over Tailscale, with certificate-pinned HTTPS.

Requires your own Grok Build install (SuperGrok / SuperGrok Heavy / X Premium+) and the TethrX bridge running on your computer (npx tethrx-bridge). Setup takes a couple of minutes.

TethrX is an independent client and is not affiliated with, endorsed by, or sponsored by SpaceXAI. "Grok" and "Grok Build" are trademarks of their respective owner.
