Chat
Ask the assistant in your own words. It calls campus services through plugins and shows the result as a card or a form. Actions that change something wait for your confirmation.

Your account and data
- Your student ID, password and authenticator secret are stored only on your phone, in Android’s encrypted storage.
- The app connects to campus systems directly from your phone. Our server never sees your account.
- Chats go to the AI provider you choose, with your own API key. DeepSeek is the default; any OpenAI-compatible provider works.
- There are no ads, no analytics and no tracking.
Adding a campus service
A plugin is a folder with a PLUGIN.md file and tool files in YAML. It lists the websites it may contact, and the app handles sign-in and permissions. You can share a plugin with a link.

The app is free. The assistant uses your own API key from an AI provider, and you pay the provider for what you use.
Not yet. The app runs on Android 7.0 or later.
Most features do. A few university services, such as the finance system, only work on the campus network.
The app checks for new versions and asks you. Tap Update; it downloads the new APK and opens Android’s installer, and your data stays. Small fixes arrive automatically without a new APK.
Every APK is built by GitHub Actions from a tagged commit and signed with the same key. The release notes list the fingerprints of the APK and of the signing certificate.
