Export MP4 for sharing, SRT for separate captions and .postproj to reopen your work. When replacing a source video, check relinking and timing before exporting again.

Start with the wizard

Open a video, follow the steps and preview before export. No terminal commands or coding agent are required for the desktop interface.

Add an agent when needed

Use a compatible CLI with your own account. Setup only offers to install Antigravity when Claude Code, Codex and Antigravity are absent. API usage and compute are separate costs.

Common questions

What do I need on Windows?

Use Windows x64 and follow the release setup guide. First use may require model downloads; download and processing times depend on your machine and connection.

Do I need a GPU or coding agent?

Use the wizard directly without a terminal. CPU processing is available; check setup guidance for each model. A coding agent is optional and uses your own account.

Where are my video and script processed?

Local steps run on your machine. If you select a cloud service for an operation, the selected inputs go to that service; review the configuration before sending them.

Does the app price include AI images?

No. API usage, compute and provider accounts are separate costs. Saving a MODE stores settings for your next project.

Can I reuse a project with another video?

A .postproj keeps settings for reopening. Relinking checks the audio; review timing before exporting a replacement video.

Where do I manage trials, downloads and devices?

Open your app library to see your account status and available releases. A license covers one PC; device transfer and recovery go through support. Your exported files remain yours after expiry.
