PianoReader: Browser-Based Piano Tutorial Parser

Tired of flashy piano tutorial videos? Meet PianoReader, a browser-based tool that parses piano tutorial videos and outputs sheet music and chords – all without server-side processing. Leveraging HTML canvas for video frame processing, it uses user-defined key positions and image analysis to detect pressed keys. The result? Readable sheet music. While currently limited to white keys and processing speed is dependent on frame rate, it's already useful for learning simpler songs.
