Monitorizo

Monitorizo focuses on one narrow but genuinely useful question: is this Amazon price good right now? Instead of brute-force price history charts, the extension compares the item you are viewing against the same product in non-Amazon stores around the world and weighs demand, supply, competition and market trends into a single intelligent verdict. The result appears as a short on-page message telling you whether to buy immediately or wait.

The extension runs automatically in the background while you shop on Amazon, so there is nothing to configure and nothing to learn. Beyond the instant verdict, it lets you track products and receive notifications when a price drops, either when it falls below a threshold you set or when it drops generally. That turns casual browsing into a lightweight deal-monitoring workflow.

Monitorizo is published by an independent developer on the Chrome Web Store and is free to install. It is localized for Spanish-speaking users, collects no personal data according to its store disclosure, and works as an unobtrusive companion layer on top of Amazon rather than a full shopping platform.
