Start with UCP Repeater
Use the offline core on Android or the Python companion on your computer.
Browser PWA
Open the PWA, then add built-in actions or teach your own. Enter parameters, prepare the command, review, and confirm before execution. Use QR & JSON for export or optical scanning.
Install using your browser menu or Safari Share → Add to Home Screen. Wait for Offline app files ready in Data & install. Commands, notes and outputs stay in this browser’s IndexedDB. Export backups before changing browsers or domains. The browser edition has no Python receiver pairing or automatic AI synchronization.
Android
The available test APK is version 1.0, a debug build. Latest source is version 1.2.0; rebuild and sign it for a current release.
- Download the test APK from the landing page to an Android 8.0+ device and install it using the device’s installation controls.
- Follow onboarding. Try the phrase
echo thiswith parameters{"text":"Hello, offline world!"}. - Generate a QR code, then scan it from another display or import its image. Review the decoded command.
- Choose Execute again and confirm. Then choose Return exact saved result to retrieve the prior output.
Python companion
Extract the source ZIP. Python 3.10+ is required. On Windows use start-python.bat; on macOS/Linux run start-python.sh. The first setup installs dependencies and needs internet. Local core operation can then work offline.
The newer reply translator starts with start-reply.bat or start-reply.sh. Its guide is README-UPDATE.md inside the source.
Optional receiver
Android pairing requires a reachable computer running the compatible receiver over HTTPS with an appropriate certificate. Follow docs/RECEIVER.md in the source package. No automatic cloud AI synchronization is provided.
