Paste your Suno link and get a captioned 9:16 or 16:9 lyric video in under two minutes — captioned automatically from the lyrics, no transcription, no Premiere, no timeline.
Skip the export and the copy-paste. Paste your Suno song link and CaptionFit fetches the track, reads its lyrics, and captions it automatically — every line timed to the vocals. There is no transcription step, and the project opens ready to style and export.
Drop in a suno.com/song/… link and your lyric-video project opens already captioned — no upload, no pasting lyrics.
It uses Suno's own lyrics, so every word is spelled right — English, Spanish, Japanese, Georgian, anything Suno generates.
Each line is aligned to the audio so captions land exactly on the beat — no manual nudging.
Paste the lyrics Suno, Udio, or Songer generated and CaptionFit snaps each line to the exact beat — no manual timestamp nudging.

Suno, Udio, and Songer make it trivially easy to generate a finished song in minutes — but they don't make the video. Most AI music creators end up spending more time in Premiere or CapCut building a lyric video than they spent making the song itself. CaptionFit closes that gap: paste the song's link and it captions the track automatically — or upload the audio and paste the lyrics.
Because CaptionFit uses the lyrics you paste rather than auto-transcribing, the words are always exactly right — no AI mishears, no cleaning up garbled lines. And since Suno, Udio, and Songer already give you the lyrics, there's nothing extra to write. The full workflow from generated song to posted lyric video takes under five minutes.
Posting to multiple platforms? CaptionFit exports 9:16 for TikTok, Reels, and Shorts and 16:9 for YouTube from the same upload. If you also share spoken or podcast-style content, social media creators tools and lyric video tools for musicians cover those workflows too.
