Chord ai uses recent advances in artificial intelligence to give you the chords and beats of any song automatically and reliably. You won't need anymore to look for the chords of a song on the web. Chord AI listens to the music played from your device or around you and shows you the chords instantly.

In its basic version, Chord AI is able to recognize the following chords: 
- major and minor
- augmented, diminished
- 7th, M7th
- suspended (sus2, sus4)

In the Pro version that you can get with just a one-time in-app purchase, Chord ai can recognize thousands of advanced chords using the latest advances in the field of machine learning such as:
- power chords
- half-diminished, dim7, M7b5, M7#5
- 6th, 69th, 9th, M9th, 11th, M11th, 13th, M13th
- add9, add11, add#11, addb13, add13
- 7#5, 7b5, 7#9, 7b9, 69, 11b5, 13b9,
and combinations of the above! (such as 9sus4, min7add13 etc.)

In addition, Chord ai Pro is able to detect chord inversions such as C/E where the third (E) is played as the lowest note, or Am7/G where the seventh (G) is played as the lowest note.

For guitar and ukulele players, Chord ai also comes with a massive library of chord positions.

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

How does Chord ai work? Chord ai can find the chords of a song in two ways:
1) For audio files that you have on your device or iCloud, YouTube videos, SoundCloud songs, Chord ai will process the song in a few seconds to give you all the chords of the song at once
2) Through your device microphone. Any song playing around you, or played by your device from a streaming service, is analysed with 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 chords displayed on a timeline.

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

Hey ChordAi Team!

Just wanted to thank you for bringing such an incredibly useful app on mobile! I’ve had countless hours of looking up chords on google, sometimes inaccurate or not as true to the song version I have (you know those like remix, parodies, etc).

ChordAi changed that and I’m super happy with the results I’ve gotten; I can confidently say my guitar repertoire is bigger than it’s ever been. I think if I played the piano or knew more music theory then I could benefit from it quite a lot!

It’s been over a year since I downloaded it and got the premium, but for me personally, I would love if the app could turn to landscape mode whenever the phone is held in that position. Sometimes because I have my mobile device attached to a tripod whilst holding the guitar with both hands, having it on portrait mode feels a bit fast-paced, and the fonts as well as the diagrams seem smaller too, therefore if there’s a way to turn this suggestion into a reality then it would definitely rock n’ roll it!

Still, even as it is now on the current app version, I’m pleased to have it handy so thank you again for your work! =)

First Class - super usable and fun

Played guitar now for many years. Spent ages working out songs. This app works really well. I can find a song I like - play along on you tube in real time. All the chords are there for you - OK you may need to think about where is best to play a particular chord on the neck - but this app gives you the right chords so you can quickly get to the heart of the song - sorts capo out too. So in English this app gets a “that’ll do” which is high praise indeed.

Simply Awesome

Absolutely love this app. It is surprisingly accurate for many songs I’ve tested this on. There is a slight lag between the recognition and the display so you can’t quite use for live play-along, but in terms of recording the chords used it is fantastic. I’d like it to also have the ability to export a PDF / image of the chords transcribed. Otherwise just brilliant.
