AI product read Real-time guitar and piano chord detection and display overlay on YouTube videos Helps musicians learn songs from YouTube videos by showing synchronized chord progressions in real time as the music plays, eliminating the need to manually figure out chords by ear.
1. User installs extension and navigates to a YouTube video. 2. Extension injects a 'Chords' button into the YouTube player controls. 3. User clicks the button to start analysis. 4. Extension extracts video metadata (title, artist, videoId) and sends it to the backend API (api.chord-finder.app) to look up pre-computed chords. 5. If backend has timed chords, they are displayed immediately. 6. If not, audio is captured from the video and analyzed locally using an ONNX model in an offscreen document. 7. Detected chords are displayed as an overlay synchronized with video playback.
Real-time chord detection synchronized with YouTube video playback Displays chord progressions as an overlay on the video player Supports guitar, piano, bass, and ukulele chords Uses backend API for fast chord lookup with timing data Fallback local ONNX model analysis for videos not in the backend database Visual grid/timing display showing beat positions and chord durations
Target users Guitar players / Piano players / Ukulele players / Bass players / Musicians who learn by watching YouTube tutorials or performances The extension calls an external API (api.chord-finder.app) with a hardcoded key; we cannot determine if the API itself has usage limits or paid tiers without testing the API endpoint. However, the extension code itself does not gate any features or check for subscription status. The welcome page (chord-finder.app) may contain additional information about the service, but it is not part of the extension source. Monetization
