If you searched for a "teleprompter chrome extension," here's the direct answer: this tool isn't one — it's a regular website that happens to work especially well in Chrome (and Edge) because of how well those browsers support the Web Speech API that Voice Follow relies on. That's a meaningful difference, and mostly a favorable one. Here's why.
A browser extension needs to be installed from the Chrome Web Store, granted specific permissions (often including access to the content of pages you visit, depending on what it does), and kept updated as Chrome's extension platform changes. For a teleprompter specifically, an extension doesn't offer much a plain website can't already do — reading and displaying text, scrolling it, and accessing your microphone are all things a regular web page can do directly through standard browser APIs, without needing extension-level permissions at all.
Because this tool is just a page you visit, it only ever asks for the one permission it actually needs — microphone access, and only when you click Start — Voice Follow. It doesn't get a standing grant to read other tabs, other sites, or your browsing activity, the way some extensions require depending on what they do. When you close the tab, that's it — there's no persistent background extension still running.
A true browser extension could, in principle, overlay a prompter directly on top of another site's content (for instance, over a video call page itself) rather than running as a separate window you position yourself. This tool doesn't do that — it's a standalone page, and you arrange it alongside whatever else you're using the same way you'd arrange any two windows, as covered in the Zoom setup guide and the desktop setup guide.
Sticking to a plain website keeps the tool cross-browser and cross-device by default, avoids asking for permissions beyond what Voice Follow actually needs, and means there's nothing to install, review, or keep updated separately from just loading the page. For a tool whose entire job is "display text and optionally listen to you read it," that's a reasonable trade against the narrow convenience an extension might add.
