Cursor is a code editor with AI assistance built in. It does not deploy anything, host anything, or generate a preview URL. That single fact changes the preparation for a demo video more than any other detail about the platform: before a URL and a hint can produce anything, the app has to already be running somewhere a browser can reach it. A developer coming from a platform that deploys automatically will find this step unfamiliar, and skipping it is the most common reason a first attempt fails before it starts.
GogoScreen takes a web app URL and a one line hint about what to show, then returns a narrated, edited MP4 with zooms on clicks, cursor smoothing, dead air cuts and burned in captions. It works from whatever URL you give it, which means a Cursor project deployed to any host, whether that is a platform the developer chose deliberately or a quick deployment set up just for the recording, is equally usable as a source. The tool does not care which platform wrote the code. It cares whether the URL resolves to a working app.
