What has changed in Keylark, newest first. New things reach the web page first, and the extension with its next update from the Chrome Web Store.

Save what you played
Under What you played, save every note you played from the start of a song as a MIDI file, for GarageBand or any other music program. Only your notes are in it, never the song.
A song near your computer
Press Listen to a song near you and Keylark hears a song playing out loud nearby through the computer’s microphone, from a phone, a speaker or the Spotify app. It never records it.
A part that comes round again
Through the microphone, or in a tab that isn’t a YouTube video, Keylark now notices when a part of the song comes round again, and plays it from what it heard the first time.

Keylark on a phone
Open Keylark on a phone or an iPad and the demo song is ready to play, with keys on the screen and a guide that moves on as you play.
A song near your phone
Listen to a song near you hears a song playing out loud on a laptop, a TV or a speaker, through the phone’s microphone.

The app on paper
The app is coloured in to match the site, with its settings on three cards.
15 October 2026
In the Chrome Web Store
Keylark is in the Chrome Web Store, so it can sit in Chrome’s side panel beside YouTube.
How sure it is
Each song says how sure Keylark is of its chords, and where Whole chord would play fuller.
Whole chord, for busy records
Where Keylark is unsure of a chord, Whole chord under When unsure plays it whole anyway, with a wrong note now and then.
The left hand follows the record
Once Keylark knows a song, your lowest left key plays the note the record’s bass plays.
Drawn by hand
The site is on paper now, with a drawing to show what Keylark is for.
