Instant chord progressions for your songs and solos

Chordbot is a songwriting tool / electronic backup band that lets you create and play complex chord progressions in different arrangements easily. 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 the paid 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.

* Inversion control / slash chords
Manually select chord inversions, or let Chordbot select the smoothest inversion automatically.

* Song sections
Songs can be structured into repeatable sections (verse, chorus, etc). Each section can have its own comping style/arrangement.

* MIDI/WAV export and background playback
Refine your compositions in a DAW/MIDI sequencer or play along with a virtual instrument

* Song-O-Matic
Automatic song generator with pop, jazz and experimental profiles.

Amazing App! Needs a pro version

Great for creating song starters. Excellent if you need to quickly make songs for film, television, and or online content. Would love to see a pro version where you buy download more packs of different styles and user templates.

why no 444hz?

while i was pleased to see 432hz available, why no 444hz? it stops at 443hz? honestly i dont know why just about every single music apphas to make it so hard to tune to whatever frequency we want, it really makes the whole internet conspiracy theory about 440hz seem substantial when every single app makes it just about impossible to use anything else without lagging from pitch shifting etc. i really hope the chordbot developer can make 444hz available, that would be great and make me happy with it. besides the occasional crashing and losing my work, ireally dolike chordbot and think it is really great, but i do want to use 444hz and yes, 1hz is an audible difference to me and the 443hz sounds out of tune with my guitar tuned perfect 444hz. i recommend anyone trying 444hz tuning standard, it makes everything feel happy and enriching somehow, whereas both 440 and 432 leave me feeling depressed after a while. 432 feels natural and like nature but in a way, dull, while 440 sounds mechanical and like machinery more than human music, i find 444hz is just about right, not so far from 440 that you have to relearn how to sing yet just brighter enough to feel really nice and positive.

Raw Idea Generator

While some the interface is not perfectly intuitive, this app still deserves close to five stars for its simple utility when you want to explore chord progressions and modes before exporting ideas into a DAW.
Love this app!
