The hidden gem for musicians.

Chord ai uses recent advances in artificial intelligence to find chords, beats and voicings for any song instantly and reliably. Chord ai delivers state-of-the-art accuracy beyond trained human level. You won't need anymore to look for the chords of a song on the web. You can select songs from YouTube, SoundCloud, your audio files or even use the device microphone. Chord ai is the new musician's best companion app. From beginner to pro level. Discover now the numerous features to help you improve your playing skills and your ear.

- You can select any song by browsing your audio files, SoundCloud or YouTube. This is the preferred way and Chord ai will process songs within a few seconds.

- Voicings & Positions recognition: Chord ai is the world's first app capable of recognizing not only chords, but also their specific voicing. This means that Chord ai can tell you more precisely which notes, including their octaves, are played on the piano, or which guitar/ukulele positions match best with the song.

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.

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.

Outstanding! But not Perfect.

This is a great app. Really helps narrow down the chords, and is great way to get a “feel” for chord progressions, but I can’t say it’s “perfect”. However, my guess is that is just where the state of the technology is at this point. I’m amazed at what it can do already, but will wait for more advanced tech to get to the next level. There’s a couple small picky things when it comes to the looping that I’d like to see improved as well. Have used the free version for a few weeks, and just sprung for the paid version a couple hours ago, so I will wait to hold off judgement on some of the paid features. I definitely recommend for anyone trying to figure out songs that are not easily available in tab form already. It has saved me hours of work!
