Start free.
Play all night.
01Do I need an account?
Not for the extension. Install it, open a video, click Chords. The Studio asks you to sign in with Google; the extension never does.
02What’s free, and what do Premium and Pro add?
Chord Lens is free to use. Premium and Pro lift the limits on splitting a song into stems, and give you longer songs. Chords and lyrics stay free on every plan. Key and speed are free in Chrome and, once you sign in, in the Studio, for the whole song up to your plan’s song-length limit.
03Can I use Chord Lens on my own files, or only YouTube?
Both. The Chrome extension works right on the YouTube video you’re watching (see YouTube to chords), listening to the song as it plays. To split stems, upload your own audio in the Studio (MP3, WAV or M4A, up to 50 MB). Premium exports stems as MP3 and Pro adds WAV, for your own study and practice.
04What are the six stems?
Vocals, drums, bass, piano, guitar and other (everything else), each on its own fader, so you can mute the singer, solo the bass, or keep only the drums.
05Does it record my audio or my screen?
No. The extension captures nothing from your browser and uploads none of your audio. It sends our server the YouTube video ID, and a sign-in token only if you sign in.
06Can I cancel anytime?
Yes. Cancel whenever you like; you keep the plan until the end of the period you paid for, then go back to Free.
07Is there a free trial?
Yes: 14 days of Pro, with no card. It’s for Free accounts that have never paid, once per account and email; Premium has no trial. Add a card during the 14 days and Pro carries on monthly at today’s price. With no card, day 14 brings you back to Free, and nothing is deleted.
08Which devices does it run on?
Chrome on any computer (the extension), the Studio in any browser, and Chord Lens for Mac (M1 and later). On iPhone and Android you can install it as an app from Safari or Chrome; Windows and Ubuntu apps are coming soon.
09Does changing the key change what I hear?
Yes. The recording moves to the new key while the tempo stays put, and the chart names the shapes you now play. A capo changes your fingers; the key changes the sound. Use both.
10What can I do with Chord Lens?
Play any song with its chords in time, the words underneath and the song’s sections, in the Chrome extension or the Studio. Change the key, slow it down without changing the pitch, loop any bars, and split a song you upload into six stems to mix.
11What is a stem splitter, and how does it work?
A stem splitter pulls a finished song apart into its parts. Chord Lens splits a song you upload into six stems: vocals, drums, bass, piano, guitar and other. The split runs in your browser, on your own computer.
12How clean is the separation?
Clean enough to play over on most songs, and vocals, drums and bass usually split best. Parts that share the same space, heavy distortion and old mono recordings bleed more. It’s made for practice, not for a studio master.
13Is it legal to isolate stems from copyrighted music?
Practising and studying a song yourself (learning it, transcribing a part, playing along) is broadly considered fair use under US copyright law, and similar rules apply elsewhere. That is what Chord Lens is for. Stem downloads on Premium (MP3) and Pro (WAV) are for your own personal study only, not to share or publish. To publish a cover, use the original audio under YouTube’s licensing, or get a sync license.
14Which browsers does it work in?
The extension runs in Chrome. The Studio opens in any browser, and splitting a song needs a computer with Chrome or Edge.
