ChordFold
Find song chords locally with browser-based AI.
ChordFold is a browser-based AI chord finder that helps musicians discover chord progressions from their audio recordings.
Users can select an MP3, WAV, or another browser-supported audio file, and the AI estimates chord changes over time.
Unlike cloud-based audio recognition services, ChordFold performs chord analysis locally in the browser. The selected recording does not need to be uploaded to an inference server.
After analysis, users can explore an interactive chord timeline, replay individual sections, and view guitar chord diagrams or piano note references for supported chords.
ChordFold is designed for guitarists, pianists, music learners, and anyone exploring the harmony of recorded music.
