What your agent can do

  • Text → video

    Paste notes, a script or a topic. 5 seconds to 5 minutes, 16:9, 9:16, 1:1 or 4:5, narration in the language you ask for.

  • URL → video

    Hand over a link. The agent reads the page with its own tools and sends only the extracted text.

  • Document → video

    Attach a PDF or notes. The file stays on your machine; you get the MP4, the subtitle file and the real duration back.

Only extracted text is sent; files and your API keys never leave your machine.No agent? Make one in your browserSource on GitHub
