Website Change Monitor & Alerts - Noticer

Watch any web page for changes, for free, without giving up your privacy. Noticer tells you when a price drops, an item is back in stock, a job is posted, or any page you care about changes, and every check runs on your own device. Noticer is a simple, private website change monitor. Add a page in three clicks, choose what to watch, and get a desktop alert when it changes, with a one-line on-device AI summary of what actually changed. No account needed, and the pages you watch never leave your computer. WHAT YOU CAN WATCH • Product prices and price drop alerts • Back-in-stock and sold-out (restock) alerts • Content and text changes on any web page • A specific element you pick (a price, a stock status, a number, a headline) • Job boards and new listings • Government, legal and policy pages, competitor pages, news, docs and release notes WHY NOTICER • Free. No account, no sign-up to start. • Private by design. Every check runs on your device. The pages you watch and your browsing never leave your computer. No tracking, no profiles, no selling data. • On-device AI summaries. A private AI reads each change and sums it up in one sentence, right on your machine. Nothing is sent to any server. • Notify me only when it matters. Add a plain-English rule like "notify me when the price drops" or "back in stock", and a private on-device AI decides when a change is worth an alert, so you get fewer, more relevant notifications. • Precise. Watch a whole page or a single element you pick. • See what changed. A clear before-and-after diff for every change. • Reliable. A self-healing engine keeps checking while your browser is open and catches up on anything it missed. HOW IT WORKS 1. Open the page you want to watch and click the Noticer icon. 2. Choose a whole page or a single element, and set how often to check (as often as every minute). 3. Get a desktop alert when Noticer detects a change, with a private AI summary.
