About this app

Chord ai uses recent advances in artificial intelligence (ai) to give you the chords of any song automatically and reliably. You won't need to look for the chords of a song on the web anymore!

Chord ai listens to the music played from your device, from any video/audio streaming service or played live around you, and detects the chords instantly. Then it shows you the finger positions to play the song on your Guitar, Piano or Ukulele.

It is a great tool for a novice to learn his favorite song and for an experienced musician to transcribe the details of a song when rare chords are played.

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 some video or audio streaming services).

How does Chord ai work? Chord ai can track the chords of a song in three ways:
1) Through your device microphone. Any song playing around you, or played by your device, is analyzed through your device microphone and the chord positions are shown in real time. You can go back in time and replay the song together with the chords displayed on a timeline.

2) For audio files that you have on your device, Chord ai will process the file in a few seconds chordifies this whole song at once.

3) Chord ai is compatible with the principle audio and video streaming services.

Very Good but crashes after 20 minutes or so on the free version and the paid version. Kinda annoying if you ask me. Paid $15 for the "pro" version and it crashed halfway through the first song. Really annoying to have to go back through and reset the loop. I like that I can export the chords for each song as a PDF or send the chart to the printer. Expensive, but it does what it says.

I'm using it ( the pro version ) on my ONN\Walmart tablet. In the year since I've had the app, they have resolved the screen orientation issue. In my device, it can now be viewed in landscape orientation. I love that it can export a PDF transcription. That's a very helpful feature. The AI does a pretty good job of identifying the chords. And yet just like any human being, it must learn a song or tune as well. It's akin to an electronic version of a fake book. And yet, it's a good reference.

Actually pretty good. More than I expected. Chord detection is pretty accurate in most cases. I only gave it 4 stars because there is no screen orientation. Other than that I'm quite impressed. UPDATE After the update I have to give this app 5 stars! Landscape screen has been added. I paid for the pro version. Thanks development team!
