Features

Everything the edit needs, nothing it doesn't

Highlight detection

Audio peaks, speech density, silence gaps, motion and caption keywords feed one score.

Automatic cutting

Pick 1–10 clips at 15/30/45/60s with diversity rules so moments never repeat.

Smart reframe

Center-safe crop to 9:16, 1:1 or 16:9 at 360p up to 1080p.

Caption engine

Import SRT or VTT, style font, stroke, shadow and karaoke word highlighting.

Watermarks

Drop a logo, set opacity, size and corner. Burned in on export.

Zero uploads

Video never leaves your device. No tracking, no analytics, no server rendering.

How it works

Four moves from raw footage to shorts

Step 1

Load a video

Drag in a file or paste a YouTube link to preview its title, thumbnail and duration.

Step 2

Configure

Quality, clip length, count, aspect ratio, captions and watermark in eight quick steps.

Step 3

Analyze locally

ffmpeg.wasm extracts audio while Web Audio and canvas sampling score every window.

Step 4

Export

MP4, WebM or GIF at 30 or 60fps, saved to your device and IndexedDB history.
