Since

Press the Since button on a page you care about: a price, a job posting, a policy, a roster, a schedule. The next time you open that page, whatever is new is highlighted in yellow right where it sits. Whatever changed shows the old value when you hover. Whatever is gone is one click away in a strike-through list. The corner says "since Thursday, 4:12 PM." It only remembers pages you press the button on, and only on this computer. WHAT YOU GET - New text highlighted in place, not in a separate report - Changed text with the old value on hover ("Was: $2,300") - What's gone, in a list - Since your last visit by default, or pin a moment and compare against it visit after visit - Watch one part of a busy page: click the block you care about - Counters and timestamps ignored, so a quiet page stays quiet - Cookie banners, chat bubbles, and sticky bars never count - A badge with the number of changes on the tab - Alt+Shift+S to watch a page, or to check a watched one right now - Optional one-sentence summary from Chrome's own on-device model - Open source, MIT HOW IT WORKS, AND WHAT IT WILL NOT DO It compares when you visit. It does not check while you are away, because there is no server and it refuses to poll in the background. It installs with no access to any website; pressing Watch asks Chrome for that one site, so the permission list on the extension's card is the list of sites you watch. It waits for a page to finish loading its content before comparing. Pages behind a login work because it runs in your own session. Chrome's own pages and the Web Store cannot be watched. It compares text; a changed image with the same caption is not a change to it. PRIVACY Everything stays in your browser profile. No account, no server, no analytics, no network requests. Stop or Forget deletes what Since remembers about a page immediately. The optional summary uses Chrome's built-in model on your computer; Since never downloads it on its own.
