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.

Works great once you know how to use it correctly

Update: I originally gave this app a bad review because it wasn’t getting the chords right, but then the developer responded and showed me that I wasn’t using the app correctly. If you play a song from Apple Music (like I was) you need to have your volume turned up while the song plays in the Chord ai app and while at the same time you record it with the Chord ai app and it analyzes the chords. Then it works great!
It wasn’t clear at first that this was the method for the app to analyze the songs, but I’m glad that I understand now because this is going to be an amazing tool for teaching my guitar students. Thank you so much for his app!

Developer Response ,

Hello. Thank you for your feedback. When you select a song from Apple Music or Spotify, the app will analyse it in real time through the microphone because it has no direct access to audio data. So, when your environment is noisy, it may result in wrong chord detections. When you stop recording, there will be some algorithmic cleaning which will improve the chord list to some extent but it may not be able to get every chord perfectly. Hence we rather recommend to select a song from YouTube, SoundCloud or from your own audio files, the chords will be more accurate this way. If you have any other concerns, please feel free to contact us directly at

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!

Useful, Simple, User Friendly

After several months worth of utilizing this app and I still enjoy it. I’m currently a music major and this has been very beneficial for my studies. Even the free version is helpful in learning basic chord recognition and progressions, especially for beginners learning piano or guitar. This app makes it easy to discover notes and chords plus shows you fingering placements simultaneously as it records in real time. It lets you name, save and export what you record allows you to export and save the file. No complaints so far and next term I plan to purchase the full version. Great app. Thanks for developing this 😎
