Screen Browser turns a plain-language guide into a narrated video. It signs in to your deployed web app in a real browser, follows the guide step by step, records the screen, writes and speaks the narration, adds the on-screen effects and returns an MP4. When the app changes, you rerun the guide.
The pieces
- A project is one web app: its URL, a demo user, a login gate, and the language and voice its videos narrate with.
- An auth guide tells the recorder how to sign in. It runs in a separate browser that is never recorded. Create or edit it on the project's Connection tab.
- A main guide is one video: ten to twenty-five steps in the words a colleague would use.
- A run is one recording of one guide. A check walks the guide without recording, free.
- Credits pay for finished minutes. A run that fails is not charged.
Two ways in
The app at rec.screenbrowser.com: a wizard creates the project and the first guide, an editor with a "Check" button refines it, the project page records it.
A coding agent through the MCP server at mcp.screenbrowser.com: Claude Code, Codex, Cursor or any MCP client can create the project, write the guide from the source code, validate it, start the run and bring back the video. See For coding agents.
