Chord ai
Chord ai detects chords, beats, and song keys from audio using deep learning on your phone. Load a track from YouTube, SoundCloud, local files, or your microphone and get chord charts with guitar, piano, or ukulele diagrams, plus tempo and bar segmentation from beat tracking.
Static chord websites give you crowd-sourced guesses that miss jazz extensions and altered dominants. Chord ai runs models on-device for seventh chords, diminished, and augmented shapes, and Pro adds 4-stem separation (bass, vocals, drums, other), audio-to-MIDI via Basic Pitch, and lyrics transcription through Whisper.
Musicians, cover artists, and students use it to learn songs by ear without hunting tabs online. The base app is free on iOS and Android with over 500,000 users; Chord ai Pro costs about $9 per month or $69 per year in the US via app store subscriptions.
