Our story
Why we built LrcSong
We're musicians, karaoke nerds, and content creators ourselves. We hit the same wall everyone else does — so we built the tool we wished already existed.
Manual sync takes hours
A single 4-minute song can take 45+ minutes to time-tag by hand in tools like RhythmicaLyrics or Aegisub. We rebuilt that workflow around AI so you spend minutes, not afternoons.
Existing tools are messy
Most LRC editors are unmaintained Windows-only desktop apps. We wanted one privacy-first web tool that runs everywhere — no installs, no signups for client-side tasks.
Karaoke deserves better
Word-level karaoke timing was historically reserved for big-budget anime fan-subs. We made enhanced LRC generation accessible to anyone with a laptop and an MP3.
Creators wanted one place
Producers, DJs, content creators, and language learners were juggling 5+ different tools. LrcSong combines AI transcription, format conversion, metadata tagging, and lyric viewing under one roof.

Under the hood
How AI LRC generation works
From audio file to perfectly synced lyrics in four steps — most jobs finish in under 90 seconds.
1 — input
Upload or paste
Drop an MP3 / WAV / FLAC / M4A, or paste a YouTube URL. Files up to 100 MB.
2 — transcription
AI transcription
Our backend extracts vocals, transcribes them, and aligns each line to millisecond timestamps.
3 — refinement
Smart cleanup
Punctuation, casing, romanization, and per-language post-processing happen automatically.
4 — export
Download anywhere
Export LRC, Enhanced LRC, SRT, VTT, ASS, TTML, JSON, or PDF. Or embed directly into MP3.
LRC vs Enhanced LRC

Standard LRC highlights one line at a time. Enhanced LRC highlights one word at a time — the format used by professional karaoke apps.
Standard LRC
