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.

Chord ai includes:
- Chord recognition (more precise than all other apps)
- Beats and tempo detection (BPM)
- Tonality detection
- Lyrics recognition and alignment (karaoke-like alignment)

Chord ai has a FREE version, enabling the recognition of basic chords:
- major and minor
- augmented, diminished
- 7th, M7th
- suspended (sus2, sus4)

In the PRO version, you can store playlists, and backup on your drive, and the chord recognition has more precision. It provides an optimal finger position and recognizes thousands of advanced chords 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.)
- chord inversions such as C/E are also included

Chord ai also comes with a massive library of chord positions for guitar and ukulele players. It is the ultimate guitar learning tool. Guitar tabs are not yet supported but it will come eventually.

Chord ai even works offline and it is full privacy preserving. You don't need 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 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 chordifying this whole song at once.

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

I really love this app. For the past year, I've used it very intensively to practice chords and it's visual so it makes it a lot easier to learn. After every update, it's get better and better. If I could add a feature, it would be some kind of autoplay when you have made playlists. That's one thing I really would like especially when rehearsing songs 🎵

The concept is great. The interface is friendly. Apart from the same issue of unable to play most of songs on YouTube, it sometimes get 3/4 as 4/4 beat. It sometime gets major as minor key. The concept is good for pitch changes including chords and voice, but it transpose chords to a different key only, the voice (tune) is never changed to a diffent key. I am a pro user. Please fix this!

That was one of the best music app. After latest update I can't use it for YouTube channel because of copyright detection, but the other options like browse and microphone isn't working well, and the chords are wrong and not in the right place. I use the app for education purpose, not for commercial things. If something will change please give me a sign, I change my rate. Right now this is a big disappointment.
