How it works
Upload audio
Drop in MP3, WAV, M4A, FLAC, OGG - podcast clip, song, voice memo, anything.
Pick a visual style
Animated waveform, scene-matched AI visuals, or static cover art. Add captions automatically.
Export video
Render to MP4 in any aspect ratio - 1:1 for Instagram, 9:16 for TikTok/Reels, 16:9 for YouTube.
What it can do
Audio you can see
Pick from preset waveform styles tuned for podcasts, music, and voice memos. Match brand colors. Synced to the beat.
100+ languages, word-level
AI transcribes the audio and adds word-level captions in your brand style. Translate to any language with one click.
Scene-matched B-roll
Want more than a waveform? Toggle AI visuals - each section of the audio gets a matching B-roll clip pulled from stock or generated with AI.
When audio needs to be social
Podcasters
Episode teasers for social
Pull a 30-second highlight, generate an animated-waveform video with captions, share to Instagram and Twitter. Drives subscribes.
e.g. Make a 30-second episode teaser for Instagram
Musicians
Song teasers and lyric videos
Convert a song clip into a shareable Reel with animated waveform and lyric captions. Faster than animating in After Effects.
e.g. Make a 30-second song teaser with lyrics for Reels
Brand teams
