Chord Detect

Chord Detect is an intelligent audio analysis tool that automatically identifies and transcribes guitar chords from your music recordings. Simply upload an MP3, WAV, OGG, M4A, or FLAC file (up to 50 MB, 15 minutes max), and the tool analyzes the audio to extract chord progressions, displaying them synchronized with lyrics, song key, BPM, and time signature.

The service offers a free trial with 60 seconds of chord detection without requiring an account, and a full first song analysis free with account creation (no credit card needed). Each result includes chord diagrams, fingering positions for guitar, and a complete breakdown of all chords used in the song.

Chord Detect is ideal for musicians, songwriters, producers, and students who want to quickly learn chord progressions from existing recordings, create chord charts for covers, or analyze their own demos and rehearsal recordings.
