How it works

1
instant

Upload audio

Drop in MP3, WAV, M4A, FLAC, OGG - podcast clip, song, voice memo, anything.

2
30 seconds

Pick a visual style

Animated waveform, scene-matched AI visuals, or static cover art. Add captions automatically.

3
minutes

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

Repurpose voice content

Turn voice memos, internal recordings, or podcast appearances into shareable videos for your marketing channels.

e.g. Convert a podcast guest appearance into a LinkedIn video
