AI Text Summarizer

Summarize the page you are reading

This tool cannot fetch another site for you: a browser cannot read a different address's text, and there is no server here doing the fetching because everything runs on your device. So to summarize a live page, use the bookmarklet. It grabs the text on the page you are viewing (or just your current selection) and sends it here, where the summary is generated locally.

Drag this to your bookmarks bar, then click it on any page:

📄 Summarize this page

Select some text first to summarize just that part, otherwise it takes the main content. Long pages are trimmed to fit the on-device model.

How it works, and what you need

The summary is produced by your browser's built-in AI (the Summarizer API), which runs a small language model directly on your machine: Gemini Nano in Chrome, Phi-4-mini in Edge. Your text never leaves the browser, there is no sign-up, and it works offline once the model is downloaded.

It works in Chrome or Edge 138 or newer on desktop (Windows, macOS or Linux) with enough free disk space and memory for the model. The first run downloads the model once (a few hundred MB in Chrome, larger in Edge), and the very first summary can take a while as the model loads; after that it is quick. If your browser does not support it, the tool will tell you at the top of the page. For the full requirements see the Chrome or Edge docs.
