Screen Browser records narrated demo and tutorial videos of your deployed web app. You describe the walkthrough in plain language, or let your coding agent write it from your source code. A real browser signs in with a demo account, follows the guide step by step, records the screen, narrates it and adds on-screen effects. You get an MP4 plus a GIF, subtitles, chapters and a thumbnail, and a webhook or the API can deliver them wherever you publish. When the app changes, edit a line and rerun.
For coding agents, Screen Browser is an MCP server with a companion skill. The skill teaches the agent how to write guides that work on the first run; the server creates the project, validates the guide, starts the recording and returns the video. Claude Code, Codex, Cursor or any MCP client can use it. Sign-in happens in the browser; there is no key to paste.
Plans start at $49 a month, sized in minutes of finished video. A run that fails is not charged, and checking a guide before recording is free.
A web app reachable over the internet, and a demo user that signs in with email and password: no OAuth, no two-factor codes, no captcha. Mobile means the app's mobile layout, not native apps. Videos are capped at five minutes. There is no free plan.
What you get: Narrated walkthrough videos from a plain-language guide. MCP server and skill for Claude Code, Codex, Cursor and any MCP client. Real browser signs in with a demo account and records the screen. On-screen effects: highlights, zoom, captions, tooltips, chapters. MP4, GIF, subtitles, chapters and thumbnail, delivered by webhook or API. Rerun after every product change by editing one line.
