SPOTLIGHT

Load a song

Paste a YouTube link, then paste that video's transcript. Hit Start and sing.
Audio files (mp3, m4a) play with a black background.
Or paste timestamped lyrics directly above.
Negative = lyrics highlight earlier. Positive = later. YouTube caption timestamps often drift on real songs — you can also nudge this live while a song plays.

How do I get the transcript?

On the YouTube video page, click the "..." (more) under the video, choose Show transcript, then select all and copy. Paste it above. The lines look like a timestamp (0:00) followed by the words — Spotlight reads those timestamps to sync the highlighting. Auto-generated transcripts work but may be rough; creator-provided lyrics are cleaner.
