Chord AI uses recent advances in AI to give you the chords of any song automatically. You won't need anymore to look for the chords of a song on the web.

Chord AI works offline. You don't need to have an internet connection unless you want to play a song from YouTube or a streaming service.

Chord AI currently recognizes all major and minor chords. Recognition of rare chords such as seventh, ninth, augmented, diminished chords etc. will be available in later updates. Please be patient :)

Chord AI can find the chords of a song in two ways:
1) Through your device microphone. Any song playing around you, or played by your device, is analyzed through your device microphone and the chords of the song are shown in real time. You can go back in time and replay the song together with the chord displayed on a timeline.
2) For audio files that you have on your device or iCloud, Chord AI will process the file in a few seconds to give you all the chords of the song at once

Regarding the In-App Purchase: You will be able to use Chord AI for free for a few minutes each day, which is probably enough for many users. After the limit is reached within a day you may be asked to buy the in-app purchase, which will give unlimited use. This is not a subscription, you just need to pay once for a lifetime.

Regarding the 17+ age restriction: This is simply enforced by Apple for any application which lets you browse YouTube videos freely.

Wow. It tells me the guitar chords I play.

If I strum a few chords on guitar, it identifies the majors and minors quite accurately. It doesn’t get harder chords like C7 or D6. But so far so good. I’d like to see more !

One enhancement request : it would be nice to output the list of chords as a text file or as a list of tabs (when one clicks save).

Simple to use and remarkably accurate!

I play in a band at work and we’ve started using the app to find the chords from songs we’d like to play from everyone’s playlists. The tool is simple to use and has proved to be remarkably accurate! This is much easier than having to browse through multiple websites that don’t always have the right version of a song you’d like to play... Well done with this one!

I hope they add more chords for the app to recognized because it’s a lot of fun to play random strings and see what it is.
