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.

For a while I constantly got a message "The YouTube video player raises an unexpected error, please try again" Following my initial review, the devs reached out and got some details and video shots of the problem. A week later, they came back with an update that fixed the issue! Very impressed with the app and the team's determination to keep it working properly. Brilliant app for figuring out that song you just heard!

Thank you for reporting the bug. Can you please send an email to android.support@chordai.net so we can help with your issue? Please send a video screen recording or screenshots of the error so we can try to reproduce the bug on our test devices. A possible reason why it works for us is that we have the chrome browser installed on our devices.

I've been using the Pro version for sometime however recently, virtually every song / track I try to access on YouTube now flashes a "media unavailable, copyright protection detected" message. This once go to app has now become virtually useless - especially as the same on line content is still accessible via other apps. Don't know if I've got a setting wrong somewhere, but this is very frustrating... Update - song accessibility now appears to have become even more limited.

Literally just a music player. Doesn't identify chords. Everything you try to do it takes the user to a subscription page. How are users meant to demo the app if it doesn't show you how accurate it is. Free version doesn't show you any chords at all. Not even incorrect chords. Not even cords like your mum got you from the market when you were a kid.

Thank you for the feedback. For any song the free version provides chords, beat tracking, tonality, all this for free. They are additional services in pro, but a large majority of the users enjoying the app use the free version.
