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, 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.
