Phishing Checker for Gmail

About

Phishing Checker for Gmail helps you spot dangerous emails before you fall for them.

When you open a message in Gmail, the extension automatically scans it for common phishing signals and shows a clear warning right inside the email — explaining, in plain language, exactly why something looks suspicious.

WHAT IT CHECKS
• Mismatched or look-alike sender domains (e.g. paypa1.com instead of paypal.com)
• Links whose visible text differs from where they actually lead
• Suspicious or newly-seen domains and known bad domains
• Urgency and pressure tactics ("act now", "your account will be closed")
• Requests for passwords, payment details or personal data
• Other common social-engineering red flags

PRIVACY FIRST
• Everything runs locally in your browser.
• Your email content is never sent to any server.
• No tracking, no analytics, no accounts.

WHY USE IT
Phishing is the number one way accounts get hacked. This extension gives you a second pair of eyes on every email, in language anyone can understand — no security expertise required.

Open-source. Free. Works directly inside Gmail.
