Nudge is a browser extension that provides real time trust scores for websites to help users identify scams, phishing attempts, and fraudulent sites. Its primary function is to evaluate the legitimacy of any website a user visits, drawing on a database of over 1.1 million verified domains across 177 countries. The tool is designed to operate silently in the background, delivering an assessment without requiring user interaction or manual checks. The extension offers several key capabilities. It generates a trust score for every website visited, provides scam and phishing alerts, and supports safer online shopping by flagging potentially dangerous pages. Nudge does not rely on a blocklist or filter but instead uses real time intelligence to analyze each page. The tool is available as a free extension for Chrome and Firefox, and it can also be used on Android devices through the Firefox browser. No account creation or subscription is required for its use. Typical use cases include verifying the safety of unfamiliar shopping sites, checking links in emails or messages for phishing risks, and gaining general confidence when browsing the web. The workflow is straightforward: a user installs the extension, and it begins working automatically on every page they visit. The user receives a trust score and any relevant alerts without needing to open a separate interface or take additional steps. The extension runs silently in the background and does not collect or track user data, operating on a principle of privacy protection.
