Chordbot is a songwriting tool / electronic backup band that lets you create and play complex chord progressions easily on your phone or tablet. Just add some chords, select a comping style and hit play.

Use it for songwriting experiments, to create backing tracks for practicing solos, or just for fun. Easily create arrangements and mixes by selecting from hundreds of piano, guitar, synth, bass and drum tracks.

This is the full version of Chordbot with all features enabled. There is also a free evaluation version (Chordbot Lite) with disabled save/export features that you could/should try before buying this version.


  • 60+ chord types
    Including classics like AugAdd2 and Min7(#11), in all inversions.

  • 70+ comping style presets
    Simple but usable arrangements that won’t get in your way.

  • 400+ instrument tracks
    Individually mixable dynamic instrument tracks that can be combined to form unique comping styles.
