FAQ
Is it free?
Yes — EarChords is free and runs entirely in your browser. There’s no sign-up and nothing is uploaded to a server.
How does it find the chords?
It uses on-device neural pitch detection plus harmony modelling to hear the notes and work out the chord at each moment — the same way a musician does by ear, in seconds.
Do I need the audio file?
No. You can play the song out loud, capture a tab that’s playing it, or upload a file. Whatever you use, the audio never leaves your device.
