Rook

Your personal AI agent in Chrome. Bring your ChatGPT plan or an OpenAI-compatible model. Send tasks from your computer or phone.

The personal AI agent, except it's yours. Rook is free to install and use: bring your own ChatGPT plan or an OpenAI-compatible model, and Rook runs in your Chrome, on your laptop or on a cloud VM you own. The new hosted personal agents run on the vendor's model, in the vendor's cloud, on the vendor's plan. Rook gives you the same kind of agent, with its own files, its own schedules and its own tab groups, on the model account you already have. Private by default, 100% on your device. Rook has no server of its own and no Rook account, and we never store your conversations, files or browsing. Nothing leaves your computer until you connect something: prompts go only to the model provider you sign in with, and the connectors and sites you use receive only what those tasks send them. Self-host it: run the same Rook on a cloud VM you own, and talk to it from your phone or your terminal. Your model. Sign in with ChatGPT and Rook runs on your plan, with the model and reasoning effort you choose and your plan's limits shown. Or point it at any OpenAI-compatible endpoint with tool calling, including a local model through Ollama or LM Studio. With the rook CLI running, rook model codex reuses the Codex sign-in on that machine. Its own workspace. Rook keeps its own files, a bash shell, saved scripts and schedules, works in its own tab groups, and opens only the local folders you share. In a dedicated, managed Chrome profile it signs in to its own accounts and puts its own name on its work. Talk to it from your terminal. The rook CLI (Apache-2.0) lets Claude Code, Codex, Cursor or any shell agent on the same machine hand Rook web work: sites behind a login, pages that need a real browser, files in its workspace. For example: rook ask "Open the team wiki and list next week's on-call rotation". Routines. Save a job as an automation. Run it on demand, on a schedule, or once per spreadsheet row, and read every past run. Schedules run while Chrome is open on an awake computer. Optional, off until you turn them on: a phone companion with a live view of the tab Rook is working in, Slack and Discord with your own bot, Google Workspace, and dozens of MCP connectors. What still waits for you: a CAPTCHA, a hardware key, or a phone approval. Rook pauses in that tab and tells you. Compared with Meta Muse, xAI Grok Bot, OpenAI dots and Gemini Spark: each runs on its vendor's model and plan, with its computer in the vendor's cloud. Compared with OpenClaw: both let you bring your own model and run on your own hardware; Rook lives in Chrome, on your laptop or your own VM, and takes tasks from Claude Code, Codex or Cursor.
