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.
