Chord Lens: AI YouTube Chord Finder

See real guitar chord diagrams on any YouTube video — synced to the music, with key, BPM, and one-click capo transposing.

Chord Lens shows the actual guitar chord shapes over any YouTube video, synced to the music. Not just chord names — fingerings you can play. 🎸 STOP GUESSING. START PLAYING. Most chord finders give you letters: G, Em, C, D. Great — if you already know every shape. Chord Lens gives you the fretboard diagram, right when the chord hits. Your hands know what to do before your brain finishes reading. One click on any YouTube video. The chord chart appears over the player and follows the song, beat by beat. 🔍 WHAT YOU SEE ON SCREEN ➤ A five-card carousel centered on the chord playing RIGHT NOW ➤ The chords coming next, so you can move your fingers early ➤ Real guitar diagrams with finger positions — not just chord names ➤ The song's musical key, detected automatically ➤ The song's BPM, so you know the tempo before you count it in 🎯 CAPO SUPPORT THAT ACTUALLY WORKS Song sitting in Eb? Bar chords everywhere? Open the player's ••• menu and pick any capo fret from 1 to 12. Every chord name and every diagram transposes instantly. Your setting is remembered for next time. This is the feature most chord finders forget. Real guitarists use a capo. Chord Lens knows that. 🪟 THE WHOLE SONG, IN ITS OWN WINDOW Click Sheet and the full chord chart opens in a separate window — every numbered bar from intro to outro, laid out like the chart you'd tape to a music stand. Resize it, drag it to a second monitor, or park it beside the video and leave YouTube full-screen. ➤ The entire progression at a glance, not a five-chord window ➤ The current beat lights up and the sheet scrolls itself as the song plays ➤ Click any bar to jump the video straight to it ➤ Pick how many bars per row — or let it fit whatever size you drag the window to ➤ Capo and Simplify live in the sheet too, so it transposes right along with you Scroll back to check a section and the sheet stops chasing the playhead until you're done reading. ⚡ INSTANT ON REPLAY Chord Lens analyzes audio on a server, not in your browser — so your laptop fan stays quiet and your tabs stay fast. Once a video has been analyzed, the chart loads immediately. Come back tomorrow, next week, next month: instant. 🎼 HOW IT WORKS — 3 STEPS 1️⃣ Install Chord Lens 2️⃣ Open any YouTube song and click Chords 3️⃣ Play along No account. No signup.
