About

TethrX

Features
Read full description

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, from a notification on your lock screen, or from your Apple Watch. • Plan mode: Grok drafts a plan, and you review and approve it before it builds. • Choose the model and reasoning effort for each session. • Review what changed: per-file diffs, then commit or discard from your phone. • Queue follow-ups, branch sessions, schedule recurring tasks, dictate messages, and keep a library of reusable prompts. • Live Activities, widgets and a watch complication show what Grok is doing at a glance. • No accounts, no tracking, no third-party servers. Your phone talks only to your bridge, directly or 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: open the bridge's pairing page and scan its QR code. 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.
