Everything you need, nothing you don't
Prompt-Driven Editing
Describe the video you want in plain English. The AI selects clips, sequences them, adds transitions, and renders your timeline.
AI Narration
Auto-generated voiceover scripts timed to your video. Use cloud TTS or clone your own voice locally with Chatterbox — your voice data never leaves your machine.
Animated Subtitles
TikTok-style word-by-word subtitles with precise timing. Multiple styles to match your content.
Transparent Decisions
Every edit decision is saved as readable, editable JSON. Tweak the timeline by hand and re-render instantly — no AI call needed.
Batch Production
Run the same footage with 10 different prompts to get 10 unique videos. A/B test edits at scale without touching a timeline.
NLE Export
Export rough cuts as OpenTimelineIO for finishing in Premiere Pro, DaVinci Resolve, or Final Cut Pro.
How it works
Point it at your footage
Pass a folder of raw clips. Director's Cut detects scenes, transcribes speech, and builds a visual understanding of every shot.
Describe what you want
Write a prompt: "30-second product demo with narration" or "highlight reel of the best action shots." The AI makes the editorial decisions.
Get a finished video
Out comes a rendered MP4 with transitions, narration, and subtitles. Publish directly to YouTube or TikTok, or export to your NLE for final polish.
Built for people who'd rather ship than scrub timelines
