About Gmail Phishing & Scam Detector - TrustScan AI Email Checker

Stop wondering "Is this email real?" TrustScan is a Gmail security Chrome extension - an automatic phishing scanner and scam checker that reads every message the moment you open it. Get a clear Green / Amber / Red trust score before phishing, scams, or AI-generated emails can cost you. Privacy-first · Manifest V3 · GDPR-compliant · No email content stored ━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY GMAIL USERS CHOOSE TRUSTSCAN ━━━━━━━━━━━━━━━━━━━━━━━━━━━ ➤ Catches what Gmail's spam filter misses Gmail blocks obvious spam - but the dangerous emails are the ones designed to look real. TrustScan analyzes those. ➤ Detects AI-written & ChatGPT-generated emails Scammers now write phishing emails with ChatGPT, Claude, and Gemini. TrustScan flags AI writing patterns the human eye can't see. ➤ Spots phishing, BEC, wire fraud, and fake-invoice scams Recognizes business email compromise, fake CEO requests, real estate wire fraud (fake wiring instructions near a closing date), payment-redirect fraud, fake invoices, and credential-harvesting attempts. ➤ Verifies deepfake & AI-generated images Hover any image in an email - TrustScan checks if it's AI-generated or manipulated. ➤ Plain-English explanations Every verdict tells you exactly why - "impersonates a known brand," "AI-generated writing pattern," "suspicious sender domain." ➤ Zero workflow change No copy-pasting. No separate tool. No clicking. The trust badge appears automatically on every email you open. ━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✔ Automatic background scanning in Gmail ✔ Instant trust score badge (Green / Amber / Red) ✔ AI-generated email detector (ChatGPT, Claude, Gemini) ✔ Phishing and scam detection ✔ Business email compromise (BEC) protection ✔ Real estate wire fraud and fake-invoice detection ✔ Deepfake and AI-image verification ✔ 50 scans included to start - sign in with Google, no card required ━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. Click "Add to Chrome" and pin TrustScan. 2. Open any email in Gmail. TrustScan scans it in the background. 3. See the trust badge - green, amber, or red - with a one-line reason. That's it. No settings to configure. ━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY & SECURITY ━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✓ No email content is stored. Ever. ✓ Email text is analyzed in real time and discarded immediately. ✓ GDPR-compliant. ✓ Your data is never sold and never used to train AI models. ✓ Built on Chrome's Manifest V3 security standard. ✓ Verified developer domain (trustscan.email). ✓ Compliant with Google API Services User Data Policy. Full policy: https://trustscan.email/privacypolicy ━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO TRUSTSCAN IS FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━ → Anyone using Gmail who has ever asked "is this email real?" → Homebuyers and sellers protecting a wire transfer at closing → Small business owners targeted by invoice fraud → Finance teams handling wire-transfer requests → Founders and executives targeted by BEC attacks → Recruiters and HR teams receiving fake applicant emails → Older relatives - install once, protect them forever ━━━━━━━━━━━━━━━━━━━━━━━━━━━ COMPATIBILITY ━━━━━━━━━━━━━━━━━━━━━━━━━━━ Works on Google Chrome, Microsoft Edge, Brave, Opera, Arc, and every Chromium-based browser. Gmail web only. ━━━━━━━━━━━━━━━━━━━━━━━━━━━ FREQUENTLY ASKED QUESTIONS ━━━━━━━━━━━━━━━━━━━━━━━━━━━ Q: Does TrustScan have a free plan? A: Yes. TrustScan includes 50 scans to try it out, with sign-in via Google - no credit card required. Paid plans start at $5/month for ongoing, higher-volume protection and more advanced detection. Q: Does TrustScan read or store my emails? A: TrustScan analyzes email text in real time to generate a trust score. It does not store, save, share, or sell your email content. Q: How is this different from Gmail's spam filter? A: Gmail filters obvious spam. TrustScan analyzes the emails that get through your filter - the dangerous ones built to fool a human. Q: Can TrustScan detect ChatGPT- or AI-written emails? A: Yes. TrustScan uses writing-pattern analysis to flag emails likely generated by ChatGPT, Claude, Gemini, or other large language models. Q: Does it detect real estate wire fraud? A: Yes. TrustScan checks the sender's domain against who they claim to be and flags fake wiring-instruction and closing-document emails before you act on them. Q: Does it work on the Gmail mobile app? A: Not currently. TrustScan works on Gmail in a desktop browser. Q: Will it slow down Gmail? A: No. Scans run in the background and add no noticeable latency. Q: What permissions does TrustScan need and why? A: Read access to gmail.com so it can analyze emails you open. Nothing else. No browsing history, no other tabs.
