Why Flow?

Most open-source YouTube clients give you playback but no way to discover new content. You either use the official app and get tracked, or you use an alternative and lose recommendations entirely.

Flow gives you both. The recommendation engine learns what you like by analyzing your watch behavior locally. It never leaves your devices. You can inspect everything it knows about you, adjust it, or wipe it at any time.
