Description

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.

Amazing power!

I’ve always wanted to do Roman numeral analysis on my favorite pop songs, but I’ve been too lazy to do it on my own. This app makes the whole process so much easier! The money to unlock all the chords was well worth it. Sometimes I disagree with the app’s judgement on some of the chords. There were a couple of times when I was sure a certain chord was fully diminished, but the app marked it as something else entirely. However, most of the time it seems to be pretty spot on!

I wish it would let me manually override the identified key, because that is something it gets wrong fairly often (at least with songs I listen to!) That’s my only complaint. Love this app. Thank you for making it.

Decent for its price point but don’t expect full accuracy

Guitar chord diagrams do not match the chords played when you tap on said diagram. The (audible) voicings are always incorrect, 100% of the time. The app’s algorithm doesn’t understand how to translate a guitar chord diagram into midi in terms of octaves and voicing. Even a beginner would notice that the app isn’t playing chord shapes properly. Chord recognition has improved but has ample room for more consistent accuracy; extended guitar chords can be tough for this app to pick up correctly and it does much better with keyboards. Sometimes it registers simple (and repeated) triads incorrectly and inconsistently which is puzzling. It gets confused between root position and inversions in a lot of these cases (of simple and repeated triad chord patterns). 11th and 13th chords are decently identified but still has issues with inversions and correctly settling on a logical chord name based upon an obvious and established tonic. Diatonic chord name analysis might be out of the scope for an app of this price point. Alternate guitar tunings isn’t something this app offers. I don’t see that feature coming since the chord diagrams and how they’re represented in midi aren’t the same. If you’re a “what chord is that??” kind of musician I would still recommend the paid version, but be prepared to dig out a midi keyboard or a guitar to get every chord-color and the exact voicing nailed down and identified.

Developer Response ,

Hello. Very sorry for the crashes issue. We have updated the app after the review. Could you please let us know if it solved the issue? That would be very helpful.

Great core functionality, weak workflow

The basic chord recognition aspect of this is astonishingly good. It doesn’t always nail the exact guitar chord shape, but that would be a lot to ask. But otherwise the quality is pretty amazing.

The downside is the input and output workflow. Loading media can be a tedious process of working down through directories or playlists, starting from the very top of the hierarchy every time. If I want to look at a bunch of related files, I wish it would open up at the last place I looked rather than having to start over. But that’s a small thing; not many people have the same use case as me. What I really wish, though, was that I could have a plain text output format, perhaps chord names separated by tabs instead of HTML, which I have extract the chord data from by hand.

All that said, this is a pretty great piece of software and I recommend it highly for most people.
