ChangeSpot

Track selected page text and prices on visits. Local history and a baseline you control.

Track what changes. Ignore what doesn't. ChangeSpot helps you notice changes to the parts of a webpage that matter: a product price, headline, availability message or another text block. Open a page, click Track an element, choose a text block and review it before saving. When you visit the same page again, ChangeSpot compares it with your saved baseline. Your baseline changes only when you choose Accept new value. • Before and latest values, with detection timestamps. • Persistent local history and multiple clues for finding elements again. • Price percentage changes only for unambiguous prices with matching currencies. • Optional Chrome notifications and a badge for current changes. • English and Russian; light, dark and system appearance. FREE: up to 3 watches and 10 history events per watch. PRO: $2.99 USD once, with no subscription. Up to 1,000 watches and 500 events each within storage limits, expanded text comparison, and JSON import/export. Save your license key or backup for restoration. Applicable taxes and any localized checkout price are shown by Stripe. Page content stays on your device. No AI, analytics or server-side page scraping. Site access is requested for each site you choose; notifications require separate permission. Only open pages are checked. There is no continuous monitoring of closed tabs. Detection time is not the exact time a website changed. Canvas, closed Shadow DOM, cross-origin frames and input fields are unsupported. Up to 4,000 characters per value. Old history may be trimmed to stay within local storage limits. Unclear matches ask you to refine the selection. Offline PRO access expires within 72 hours; restoration requires internet verification. Automatic license email is not provided.
