Duo Lyrics

Synced song lyrics on YouTube, with a translation beneath each line.

Duo Lyrics shows song lyrics in sync over YouTube music videos. Each original line appears in white, with its translation directly beneath it in amber italic. You choose the translation language and follow both lines as the video plays. Lyrics come from LRCLIB, an open community lyrics database. If a song is not there, Duo Lyrics uses YouTube's automatic captions. Translation is done first on our server with Claude, Anthropic's AI model. If the server is unreachable or the daily quota is used up, Chrome's built-in on-device translation takes over. What you can do: - Read the original line and its translation together, one under the other. - Pick the translation language. The interface is in English and Turkish. - Turn lyrics on and off with the Lyrics button in the player, the toolbar icon, or Alt+L. - Shift the timing by hand with Alt+comma and Alt+period. The extension is off by default. You decide when to turn it on. Automatic sync is optional and asks for separate consent. If you allow it, 20-second clips of the video's audio are sent to our server to measure timing. Duo Lyrics does not store the audio. Without consent the extension still works, and you can fix the timing yourself with the shortcuts.
