TethrX is a native, private, and independent remote control for the SpaceXAI terminal encoding agent Grok Build. The mobile phone serves only as the control plane, while Grok and its tools and code are all on the local machine. By connecting to a small open-source bridge running on the computer, it can watch Grok work in real time, approve tool calls, has a scheduled mode, can view file changes, and can also queue up, branch sessions, schedule tasks, and leave voice messages. There is no account, no tracking, and no third-party servers. The mobile phone communicates directly with the bridge through Tailscale. It is necessary to install Grok Build and run the TethrX bridge on the computer.

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.

版本

1.1.0

A complete redesign, TethrX on Apple Watch, and more of Grok Build in your pocket.

• A cleaner design in light and dark: native lists, system colors, and text that stays readable at every size.
• TethrX on Apple Watch: see what needs you, approve or deny from your wrist (anything destructive asks first), read Grok's last reply, and dictate a follow-up. Add the complication to your watch face.
• Answer approvals and plan reviews straight from the session list, without opening the conversation.
• Choose the model and reasoning effort for each session, right from the message box.
• Typing stays instant while Grok streams its reply, and your message appears the moment you send it.
• Saved prompts go into any session from its new Prompts button.
• Safer approvals: a single tap always means allow once, and long commands are shown and judged in full.
• Live Activities and the home screen widget stay accurate, and tapping them opens the session.
• Many fixes for reliability and connection security. Update the TethrX bridge on your computer to get all of them.
