Chord Lens: YouTube Chord Finder, Lyrics & Transpose

Real guitar chords and synced lyrics on any YouTube video. Change the key or the tempo — the chart follows.

Chord Lens shows the actual guitar chord shapes over any YouTube video, synced to the music. Not just chord names — fingerings you can play. And when a song sits too high to sing or too fast to follow, you can move it. 🎸 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 📝 THE WORDS, WITH THE CHORDS OVER THEM Chords tell you what to play. Lyrics tell you where you are in the song. Chord Lens puts them together. ➤ A lead sheet: the song's words with each chord change sitting above the word it lands on ➤ The line being sung right now is highlighted, and the sheet follows along ➤ A words-only view when you just want to sing ➤ No lyrics for a song? Ask for them, and they're there next time Not every song has lyrics available, and the sheet says so plainly instead of showing you a blank page. 🎤 PUT THE SONG IN YOUR KEY The song is in Db and you sing it in A. Press the minus button next to the key. The recording moves with you. Not just the chord names on screen — the actual audio, shifted to the new key while the tempo stays exactly where it was. Sing along at the pitch that suits your voice, with the chart already naming the shapes you're now playing. ➤ Step up or down and read the new key, never a "+2" you have to work out ➤ The badge shows how far you've moved; press the key itself to snap back ➤ Db offers Ab and Eb, not G# and D# — the spellings a musician actually writes ➤ Works with the capo, not against it: drop the song to fit your voice and still capo up for easier shapes 🐢 SLOW IT DOWN WITHOUT THE CHIPMUNK The solo goes past too fast. Step the tempo down and play it at three quarters speed, with the pitch left where the band put it. ➤ The readout shows the tempo you're actually hearing, not the one on the record ➤ Moves in the same steps YouTube's own speed control uses ➤ The chart stays locked to the video, beat for beat ➤ Press the tempo to go straight back to the recorded speed Your key and your speed are remembered per video. Come back tomorrow and the song is still where you left it. 🎯 CAPO SUPPORT THAT ACTUALLY WORKS Bar chords everywhere? Pick any capo fret from 1 to 12, right in the chart header. Every chord name and every diagram transposes instantly, and 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 ➤ Key, tempo, capo and Simplify are all in the sheet too, so you can work entirely from that window 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. Changing the key or the tempo happens live in your browser as the video plays. Nothing is recorded, nothing is uploaded, and switching Chord Lens off hands playback straight back to YouTube. 🎼 HOW IT WORKS — 3 STEPS 1️⃣ Install Chord Lens 2️⃣ Open any YouTube song and click Chords 3️⃣ Play along No account.

Do I need an account? 💡 No. Install it and click Chords. 2. Does changing the key change what I hear? 💡 Yes — that's the point. The recording moves to the new key and the tempo stays put. The chart moves with it, so what you read is what you play. 3. Is that different from a capo? 💡 Yes, and you can use both. A capo changes the shapes you finger; the key control changes the sound of the recording. Set both and the chart works out what you should be playing. 4. Does it record my audio or my screen? 💡 No. Chord Lens only sends the YouTube video ID for analysis. Key and tempo changes happen live in your browser. 5. Can I turn the diagrams off and just see chord names? 💡 Yes — the Diagram button in the chart header. 6. Where do the lyrics come from? 💡 A lyrics service, matched to the song and timed by the line. Not every track has them; when one doesn't, you can ask for lyrics and they'll be there next time. 7. Live versions and covers? 💡 Works on both. It analyzes the audio in the video itself. 8. Can I see the whole song at once? 💡 Yes — click Sheet for the full chord chart in its own resizable window. Move it anywhere, including a second monitor. 🎶 EVERY GENRE, EVERY SKILL LEVEL Pop, rock, folk, blues, worship, country, jazz, R&B, metal, lo-fi, singer-songwriter — the AI chord detector reads what's in the mix. Beginners get shapes they can play today. Advanced players get progressions, key, and tempo fast enough to keep up with the song. 🎸 ONE CLICK FROM WATCHING TO PLAYING You already learn songs on YouTube. You already pause, rewind, squint at a comment thread, and hope the tab is right. Chord Lens puts the chords on the screen — with the shapes, in your key, at your speed — and lets you keep playing. Install Chord Lens and turn every video into a chord chart.
