Convert almost any music file into a songbook, and build on our new API
Jam Jam already turned audio into chords and lyrics. The same server pipeline now reads PDFs, photos, scanned sheet music, MIDI, ChordPro, plain text and pasted web pages too, and can produce whichever output you actually need in return. It runs on jam-jam.org/app/convert, in the mobile app, and now behind a public API.

The conversion engine behind jam-jam.org/app/convert and the mobile app is also a public REST API: send it a file, a link or plain text, and get back chords, lyrics, key, tempo, or a portable export. Here is exactly what it accepts, what it returns, and how to call it.
