Frequently asked questions

A remote MCP server that runs on your own Mac or Linux computer. You add it as a connector (https://heyatu.com/mcp) in an AI app such as ChatGPT or Claude. After you allow the app, it can find files, run commands and edit files on that computer.

We have tested ChatGPT (Plus and higher; web, desktop and phone apps), Claude (the free plan allows one custom connector; web, desktop and phone apps), Codex and Claude Code, and on the desktop Doubao and Qwen.

Mac, and Linux with systemd. Windows is not supported yet.

Your AI app’s own model, under your plan with that app. You need no API key. Hey Atu adds tools, not a model.

No. It works with any task that files and commands can do: find a document, tidy a folder, rename photos, sum up notes, check a log, or run tests.

Yes. A Skill tells your AI app how to do a task, and these tools let it do the task on your computer. Hey Atu does not add Skills of its own.

Pi is the open-source coding agent whose tools Hey Atu uses. The installer sets it up for you, or uses the Pi you already have. You do not need to know it.

Yes. Add Hey Atu once on the computer, then ask in the ChatGPT or Claude phone app with the same account. See Use your computer from your phone.

Yes, on and online while you use it. On a Mac, Hey Atu stops idle sleep while it runs; closing the lid still sleeps the computer. While it sleeps, your AI app shows an error.

One tool call has about 3 minutes. For a longer job, ask the AI to start it in the background and check the result later.

No. Your computer connects out to our relay. You do not open any inbound port.

No. It works with files and commands. It does not see or click your screen.

Yes. One plan covers up to 3 computers, Mac or Linux.

Yes, when the AI app asks. The tools run commands and write files with your user account’s permissions. Allow only apps that you trust, and run heyatu mcp off to stop every app at once.

The AI app’s provider, under its own policy, because the calls come from its cloud. Our relay forwards them and does not store or log them. Your computer keeps a list of calls. See Security.

OpenClaw is an open-source assistant that you host yourself. Hey Atu adds tools to the AI apps you already use, with no gateway to run. See Hey Atu vs OpenClaw.

Each account gets 100 free actions without a card. Then you can start a 7-day free trial. The plan is US$192 a year or US$20 a month; while the limited-time offer lasts, it is US$76.80 a year (US$6.40 a month) or US$8 a month, and you keep that price until you cancel. One plan covers up to 3 computers. Details on Pricing.

If you change your mind within 3 days of your first payment, write to support@heyatu.com and we refund it in full.

Not on the App Store yet; it is coming soon. Today, ChatGPT and Claude on your phone can already use your computer.

Four tabs: Chats, To-do, Updates and Wiki. In Chats you can continue a chat from your computer. What the app and your computer send each other is end-to-end encrypted.
