What the editor does
Editing needs no account. Projects and exports stay on your computer.
- Timeline editingCut, trim, move and stack clips on video, audio and text tracks.
- KeyframesAnimate scale, position, rotation and opacity. The export renders the same frames as the preview.
- Text and titlesStart from 40 text templates, then change the words, font, size and animation.
- Effects and transitionsEffects, filters, transitions and adjustments apply in one click and show in the preview at once.
- Local MP4 exportThe desktop app exports MP4 up to 4K with its bundled ffmpeg. Nothing is uploaded.
- Local projectsProjects and media live on your computer. No cloud project and no sign-in to edit.
- On-device captionsThe desktop app writes captions with whisper.cpp on your computer. The speech model downloads on first use.
- AI mediaWith an OpenNan account, generate images, video, voice lines, music and sound effects at the playhead.
Built for agent editing
Studio includes an MCP server, so an AI agent edits the same timeline you see.

Questions
Is Studio free?
Yes. Editing, local projects and MP4 export are free. Only AI generation on OpenNan uses credits, and each run shows its price first.
Is Studio open source?
Studio is source-available: the code is public on GitHub. Some packages use Apache 2.0 and the rest use OpenNan's own community license, so read the repository's license before commercial use.
Are my projects uploaded?
No. Projects and media stay on your computer. When you run an AI tool, only the inputs for that run go to the provider.
Do I need an OpenNan account?
Only for OpenNan's AI tools. Editing, export, on-device captions and agent chat with your own Claude Code or Codex login work without one.
Which AI agents can edit a project?
Claude Code, Codex CLI, Gemini CLI and other MCP clients. The desktop app has the MCP server built in.
When can I install it?
No installer is published yet. Until then, you can build Studio from the source code on GitHub.
