Chordai

Use it as a practice aid

For learning a song, compare the detected changes with what you hear and try the displayed shapes on your instrument. This is a practical starting point for practice, not an independent guarantee that every chord has been transcribed correctly.

The feature list also includes separation into vocals, bass, drums and other audio, with individual WAV exports.

Check the edition

Verify that the features you want are included on your device and plan. The linked FAQ is specifically labeled for iOS; it should not be treated as proof of identical features on every platform.

A useful practice routine

Start with a familiar song and compare the detected chord changes with the recording. Then switch to the displayed guitar, piano, or ukulele shape and play along at a slower speed. This turns the app from a passive lookup tool into a way to check whether the proposed changes make musical sense to you.

Use the key and beat information as orientation when learning a song, not as a substitute for listening. Recordings with dense arrangements, unusual voicings, or unclear audio may still need a musician to correct the result.

Separate analysis from export

The feature list combines chord, beat, and key recognition with separation into vocals, bass, drums, and other audio, including individual WAV exports.

That makes two different workflows possible: learn the harmony from a complete song, or isolate a part for closer listening. Decide which one you need before choosing a plan, because an instrument practice feature and an audio-export feature solve different problems.
