Sentinel is one of the most useful privacy and security extensions I’ve tried. I really like that everything runs locally using Chrome’s on-device AI, so my browsing data never leaves my computer. The phishing detection, OTP/password warnings, lookalike domain alerts, and dark pattern detection all work together to provide an extra layer of protection without being intrusive. It’s lightweight, easy to use, and gives peace of mind while browsing. Highly recommended for anyone who wants better online security without sacrificing privacy.

Sentinel is a thoughtfully designed security extension that focuses on real-world online scams. I like that it performs analysis on-device instead of sending browsing data to external servers, and the warnings are clear without being intrusive. Features like phishing detection, lookalike domain alerts, and protection against accidentally sharing OTPs or passwords make it genuinely useful for everyday browsing. Easy to install, lightweight, and privacy-focused. Looking forward to future updates and additional protection features.

Sentinel is a great security extension that helps protect against phishing scams, fake websites, and privacy risks while browsing. I like that it focuses on local, on-device protection instead of sending browsing data to external servers, which is a big plus for privacy. The interface is clean, easy to use, and the warnings are clear without being intrusive. It's especially useful for anyone who wants an extra layer of protection against suspicious websites and online scams. Although it's still a new extension, it has a lot of potential. Looking forward to future updates and additional features. Highly recommended for anyone who values online security and privacy!
