Chord ai

Chord ai is a free app that instantly provides the correct chords for any song. You can load material from YouTube, SoundCloud, your own audio files, or straight through your device microphone, which covers almost every situation where you want to know what is being played. Beyond chords it also automatically detects the song's rhythm, so you get a sense of the groove as well as the harmonic structure. That combination is aimed at learning: if you know the chords and the feel, you can start playing along much faster than by working it out note by note. The app is positioned as useful for beginners and experienced musicians alike.

Accuracy is not guaranteed. Dense mixes, heavy distortion, unusual tunings, and non-standard chord voicings all reduce how well the detection works, so treat the output as a strong suggestion rather than gospel. Analysis also depends on your input: a clean recording or a good microphone feed does far better than a noisy room recording through phone speakers. The app is free, but free limits and any paid tiers should be checked on the official listing. Finally, relying on automatic detection can slow your ear training, so use it as a shortcut to check your own listening rather than a replacement for it.
