A course player that streams from your Drive.
LearnFlow turns any folder of video lessons and PDFs, on disk or in Google Drive, into a structured course with notes, bookmarks and resume-from-the-exact-second. Two frontends on one Rust core. Local-first, no telemetry.

The brief
People own courses as folders of files. They want structure, notes and progress without an import step or a manifest, and video that sits in Google Drive should stream, not download to disk first.
It also had to respect the user: no account required, no telemetry, and cloud sync only if they ask for it.
What shipped
Every line below is in the build, not on a roadmap.
- Course hierarchy inferred from filenames: lessons, chapters, videos, with no import step
- Custom HTTP range-streaming proxy so Drive video plays without a local copy
- OAuth loopback sign-in; tokens stored in the OS keyring, AES-GCM encrypted
- SQLite via sqlx for notes, bookmarks and resume positions
- Web build on the Google Picker and IndexedDB, Drive-only
- Opt-in Firebase sync of progress, notes and bookmarks, nothing else
- In-browser Python via Pyodide for code-along lessons
- Windows installers (NSIS and MSI) with signed releases
