AI summarizers made it incredibly easy to skim long articles, but something got lost along the way: readers can’t always tell which exact part of the page the AI used. That’s the gap Linked Summary tries to close. We wanted a summarizer that is verifiable.
Our assumption was simple: people want to read the short version first, then jump back to the exact paragraph when they need context. So instead of building “yet another summary box”, we built a side panel that stays on the page and points back to the DOM.
Why source-linked?
Most AI summaries are helpful but opaque. Linked Summary makes them explainable: every key point can be traced to its origin. That means you can show a summary in a video, share it with a team, or review a long policy article — and still prove where it came from.
Why local?
Since this runs on Chrome’s built-in AI, the whole summarization can happen locally on the device. That makes it safe to try on internal docs, admin pages, draft content, or anything you don’t want to send to a remote API.
What happens after install
After installation, you can open any article, blog post, press release, or documentation page. When you click the extension icon, Linked Summary opens on the right and generates a summary and stores links to the source sentences. From there, clicking a summary item will scroll the page and highlight the exact sentence it came from.
Source-linked summaries
Each key point the extension generates is tied to the most likely source segment in the original page (we keep a pointer to the DOM). When you click that key point, the page scrolls and softly highlights only the relevant part — not the whole block. That’s what makes the summary verifiable.
In other words, we’re trying to bring “show me the source” transparency to in-browser AI summarization too.
How it works in practice
The actual flow is: open a page → click the extension → skim the summary → click a key point → confirm the source. Nothing leaves the browser, and the side panel stays in context. This is useful when you need to check claims quickly or take notes with original references.
Getting started
If you want to reinstall or share it with teammates, use the build from GitHub:
- Download the latest build
- Unzip the file.
- In Chrome, go to
chrome://extensions - Enable Developer mode (top right).
- Click Load unpacked → select the unzipped folder.
- Open any page and click the Linked Summary icon.
Pages to try
These are good test pages because they’re structured, public, and long enough to show the value of source-linked summaries. Open one of these and run the extension to see the scroll-and-highlight behavior.
This page is a demo for video and testing — it simulates how the side panel scrolls and highlights the source for each summary item. :contentReference[oaicite:1]{index=1}
