The only lyric-to-subtitle app that runs entirely on your Mac
LyricSync
You already have the lyrics. It adds the timing.
Questions, bugs, or requests: team@ksystudio.com
The first auto-align downloads something big?
Yes — the speech model (~480 MB) downloads once on first use, then everything runs offline. It doesn’t download again.
Does my song get uploaded?
No. Recognition runs entirely on your Mac. Nothing about your audio or lyrics leaves the computer.
What formats can I export?
SRT (for CapCut / YouTube), VTT (for web / YouTube, with section notes), and LRC (for players / karaoke).
Some lines are marked ⚠️ — what does that mean?
Those lines’ times were estimated rather than firmly anchored. Play them back and nudge if needed; the unmarked lines are fine.
Which languages are supported?
Interface and recognition support English, 简体中文, and 日本語.
