Chord AI is a mobile app automatically identifying musical chords, beats, and lyrics from any song using AI, bringing deep learning chord-recognition algorithms directly onto a phone rather than requiring manual transcription by ear.
Real-time chord recognition uses the device microphone to identify chords being played or heard, beat tracking analyzes tempo and structure into bars and beats, and key detection identifies the song’s key automatically from detected chords. Instrument separation breaks audio into four exportable stems (bass, vocals, drums, other) as .wav files, lyrics transcription runs on OpenAI’s Whisper model, and audio-to-MIDI conversion draws on Spotify’s Basic Pitch research, with a visual chord dictionary for guitar, piano, and ukulele.
Chord AI targets musicians, guitarists, and anyone learning or analyzing songs, already serving 500,000+ users with a 4.7+/5 rating on iOS and Android. A free version is available alongside a paid “complete version”; specific pricing isn’t detailed on the page reviewed.
