What is Chord Identifier?
Chord Identifier is an AI chord recognition service designed for musicians. Users can submit audio clips by uploading local files, pasting YouTube video links, enabling real-time microphone recording, or entering direct audio URLs. The system processes everything within the browser, delivering time-stamped chord sequences in seconds, along with chord diagram views and export options in TXT/PDF formats. The free version offers preview recognition, while full functionality requires subscribing to Chord Identifier PRO.
