Growl is a free Chrome extension designed to protect users from digital threats such as phishing and fraud. By flagging suspicious webpages and requiring user confirmation before interacting with them, it acts as an additional layer of security alongside built-in browser features. It automatically blocks input elements on untrusted sites and provides notifications to encourage user vigilance. Users can whitelist sites or temporarily disable blocking, allowing for flexible browsing while maintaining security.

The extension utilizes a basic detection algorithm that flags websites based on their popularity and the presence of interactive elements. Although it is in its early development stage, Growl aims to reduce digital risks by operating quietly in the background, ensuring users can browse with confidence. Future updates are expected to incorporate more advanced detection methods, enhancing its effectiveness in combating online scams.
