TethrX vs Korev

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.

Korev runs many coding agents on your Mac, each in its own worktree. The Korev phone app puts all of them in your pocket. See every agent at a glance The workspace list shows which agents are working, which wait for you, and which pull requests are ready to merge, checking or failing. Answer questions from anywhere When an agent needs a decision, Korev tells you. Pick an answer on your phone and the agent carries on. Watch the work happen Follow each agent live: the files it reads, the edits it makes and its to-do list. Approve plans on the go Read a plan before the agent starts. Approve it, ask for changes, or hand it off to a new chat. Merge when checks pass See every check on the pull request, then merge it with one tap. Ask the agent to fix failing checks or resolve conflicts. Start new work Create a workspace and give the agent a task by typing or by voice. Your Mac turns your voice into text on the device. Ask about your code Ask a question about one or more repositories. The agent reads the code and changes nothing. Private by design The phone talks only to Korev on your own Mac, over your own Tailscale network. Korev has no server and no accounts, and collects no data.
