Description
Highlight any value on a page, get notified when it changes. Value Watcher lets you keep an eye on ANY number, price, or piece of text on ANY website — without needing a dedicated app for that site. HOW IT WORKS 1. Open a webpage with something you care about — a price, a stock count, a score, a queue position. 2. Highlight the value with your mouse, just like selecting text to copy. 3. A small notification asks "Watch this value?" — click it (or right-click the highlighted text and choose "Watch this value"). 4. Pick how often to check (every 5 minutes, every hour, etc.) and save. 5. Value Watcher quietly checks that page in the background and notifies you the moment it changes. Optionally, it can even speak the change out loud. WHAT YOU CAN WATCH • Product prices waiting to drop • Stock availability ("Out of stock" → "In stock") • Flight, hotel, or ticket prices • Live sports scores • Tickets remaining on a booking page • Status pages ("Operational" → "Degraded") • Anything else you can highlight with your mouse PRIVACY-FIRST • Everything runs on your computer. Nothing is sent to a server. • No accounts, no sign-up, no analytics, no third parties. • Your list of watches is stored only in your own browser. LOGGED-IN PAGES WORK Value Watcher uses your normal Chrome session, so prices and values that only show up when you're signed in still work — without you needing to share passwords. GOOD TO KNOW • A small browser window may flash briefly on your screen when a check runs — that's the extension loading the page in the background to read the new value. It closes itself immediately. • Pick reasonable intervals. 5–15 minutes is plenty for most things; checking every minute on every page is wasteful and can drain your battery. • If a website redesigns its page, your watch may stop working. You'll see an error in the popup — just remove it and set up a fresh one. NOT GETTING NOTIFICATIONS? The popup has a "Send test notification" button to confirm notifications work. The most common fix on macOS is: System Settings → Notifications → Google Chrome → Allow Notifications. On Windows, check Focus Assist isn't blocking Chrome. Free, ad-free, and open about what it does.
