LrcSong

LrcSong is a web-based toolkit for working with synced lyrics and subtitles. Its core workflow takes an uploaded MP3, WAV, FLAC or M4A file, or a YouTube URL, isolates vocals, transcribes and aligns lyrics word by word, applies cleanup, and exports LRC, Enhanced LRC, SRT, VTT, ASS, TTML, JSON or PDF, or embeds lyrics into MP3 files. The site also lists a karaoke video creator, vocal separator, karaoke scoring, an AI melody generator, an AI song generator, an instruments studio, subtitle converters, viewers and validators, and an AI assistant. The page states that client-side tools such as converters, viewers and validators run in the browser, that uploaded audio is deleted after processing, and that the company does not use uploads to train AI models. It also states that AI lyric accuracy varies, with a published 60% word error rate for its self-hosted fallback transcriber on one benchmark, and that users should expect to edit output. Credits-based plans are Starter at $2.99 one-time (6 credits), Premium at $6.99 one-time (18 credits) and Elite at $9.99 one-time (25 credits); signup includes 3 free credits.
