TethrX
Remote for Grok Build
Free · Designed for iPad. Not verified for macOS.
Drive Grok Build from your phone and your wrist. Watch it work tool by tool, review its plans, and approve or reject each action, even from your lock screen.
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.

Ratings & Reviews

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.
