Product Overview
LyricFast is an AI lyric video maker that turns a finished track into an editable lyric video with word-level timing. Creators upload an MP3, WAV, or M4A, review the generated lyrics and word-synced timestamps, correct flagged mistakes, and then render the lyric video in multiple social-friendly formats.
It’s designed for preparing release assets for YouTube, Shorts, TikTok, and social feeds—without manually building a timeline. LyricFast generates a word-by-word karaoke-style highlight synced to the millisecond and supports tracks exported from Suno/Udio-style workflows.
Key features
- Upload MP3, WAV, or M4A tracks and generate word-level lyric timing
- Preview the full song and review AI-transcribed lyrics before rendering
- Flag words the AI is unsure about in yellow for one-click text corrections
- Render karaoke-style lyric videos with word-by-word highlighting synced to the millisecond
- Export in 16:9 (YouTube), 9:16 (TikTok & Shorts), or 1:1 (social feeds)
How LyricFast works
- 1
Upload your track file
The user drops an MP3, WAV, or M4A upload so LyricFast can detect the sung words and generate timing.
- 2
Review and correct flagged words
The user previews the full song and edits any words marked yellow where the AI was unsure.
- 3
Render in the target format
The user exports an HD lyric video in 16:9, 9:16, or 1:1 for their platform.
Use cases
- A musician finishes a track in a DAW, uploads the MP3 to LyricFast, fixes a few mis-transcribed words, then renders a 16:9 lyric video for a YouTube release.
- A creator releases short-form content by exporting a track from an AI music workflow, generates a 9:16 lyric video, and posts it to TikTok/Shorts with synchronized karaoke highlighting.
- A label or independent artist needs multiple formats for the same song; LyricFast renders 1:1 for social feeds after correcting flagged words during the preview step.
Who is it for?
LyricFast benefits musicians and music creators who want lyric videos for YouTube and short-form platforms without manually syncing captions to a timeline. It’s also useful for teams preparing release assets from exported audio files (including AI music workflow exports).
