Show HN: Phixo – explains why an email in Gmail/Outlook is phishing (chromewebstore.google.com)

Phixo has launched an AI-powered phishing protection tool designed specifically for Gmail and Outlook, enhancing email security with a four-layered detection system that operates in under three seconds. Unlike traditional tools, Phixo offers an in-depth analysis of potential threats by identifying issues such as CEO fraud, credential harvesting, typosquatted domains, and homograph attacks. The system employs a combination of on-device pattern matching, live link reputation checks, AI reasoning for deeper context analysis, and sender reputation cross-referencing to deliver real-time risk assessments, clearly indicated alongside incoming emails. This innovation is significant for the AI/ML community as it leverages advanced AI techniques to improve email security, a critical area prone to evolving threats. Phixo's commitment to privacy is notable; it ensures that users' email bodies are not stored, employing SHA-256 hashing for URL checks and utilizing OAuth for authentication without accessing sensitive information. The product's accessibility model includes a free tier for up to 10 scans daily, making it an appealing option for users seeking robust protection without a financial commitment. As it enters beta, Phixo invites user feedback for continuous enhancement, reflecting a proactive approach to cybersecurity.
