ZeroPhish: Phishing Analyzer

Automatically scans each Gmail email you open for phishing. Runs in your browser.

ZeroPhish scans any email in Gmail you’re reading for common phishing signs: mismatched sender domains, urgent or threatening language, requests for sensitive info or payment, risky links and failed authentication. Results appear automatically on the page in a clear colour-coded card. You get a score and a plain-language verdict, a list of red flags, a list of checks the email passed, and the sender, reply, and return addresses and links it found, so you can look them over yourself. Private by design: the analysis runs entirely in your browser. Emails are never uploaded, stored, or sent to any server, and the extension only reads an email when you click the analyze button. Please note: this tool is a screening aid, not a guarantee of safety. A low score doesn’t mean an email is safe, and a high score doesn’t prove it is malicious. Always verify the sender and be careful with links and attachments. Created as a cybersecurity project by Ronan Molina.
