OpenScript

Edit video by editing the transcript.

Delete a sentence in the text, the cut happens automatically on the timeline. Privacy-first: transcription runs locally in the browser via Whisper.

Project structure

• apps/web/ — The Next.js web editor: timeline, preview, WebCodecs export, and the transcript-edit panel under apps/web/src/transcript-editor/.
• apps/desktop/ — Native desktop shell (Rust + GPUI, in progress).
• apps/website/ — Marketing/waitlist site (Next.js). Independent from the editor.
• rust/ — GPU compositor, effects, masks, and WASM bindings.
• docs/ — Architecture documentation.

Getting started

The editor runs entirely in your browser — no backend required. Projects, media, and transcripts are stored locally (IndexedDB/OPFS), and transcription runs on-device via Whisper.

bun install
bun run dev:web                  # Editor at http://localhost:3000

That's all you need to edit video. Postgres + Redis are only required for the optional auth, feedback, and sound-search API routes (these fail gracefully when the services are absent). To enable them:

cp apps/web/.env.example apps/web/.env.local       # set secrets as needed
docker compose up -d db redis serverless-redis-http
cd apps/web && bun run db:migrate                  # create the auth/feedback tables

The marketing site is separate: cd apps/website && bun dev.
