Phishing emails are more convincing than ever — written by AI, personalised to your name and employer, and designed to bypass every filter you have. TrustScan is a free email phishing scanner that works directly inside Gmail, giving every message an instant trust score before you click a single link.

Email phishing is the practice of sending deceptive emails that impersonate a trusted sender — a bank, a colleague, a courier, a government agency — to trick you into clicking a malicious link, handing over credentials, or transferring money. It has been the leading cause of data breaches and financial fraud for over a decade.
What's changed is the quality. Until recently, phishing emails were easy to spot: poor grammar, generic greetings, obvious fake domains. Today, attackers use AI writing tools to craft flawless, personalised phishing emails that address you by name, reference your employer, and mimic the exact tone of your bank or HR department. An email phishing scanner that relies on keyword lists or known-bad domains is no longer sufficient.
Targeted attacks using your name, job title, or employer to appear legitimate. TrustScan analyses personalisation signals and cross-checks them against threat patterns to flag suspicious targeting.
Fake login pages, account-suspension threats, and "verify your details" requests designed to steal passwords. TrustScan flags urgency manipulation and sender inconsistencies that give these away.
Executive impersonation, vendor fraud, and payment-redirect scams. TrustScan identifies authority impersonation and financial-pressure tactics in real time.
Fraudulent payment requests that impersonate real vendors or suppliers. TrustScan detects the structural and language patterns common to invoice fraud before you action a payment.
Phishing emails drafted by ChatGPT or Gemini — flawless grammar, no obvious red flags. TrustScan's AI email scanner identifies machine-written content.
AI-generated profile photos, forged ID documents, and fake proof-of-payment images. TrustScan scans every image in the email for AI-generation artifacts.
Even without an email phishing scanner, knowing the warning signs reduces your risk. These are the eight most reliable indicators that an email is a phishing attempt.
Even experts miss these signals under time pressure. TrustScan checks all of them automatically every time you open a Gmail message.
No copy-pasting required. The phishing scanner lives where you already work — inside your Gmail inbox.
Add TrustScan to Chrome, Edge, or Brave in one click. The email phishing scanner activates automatically when you open Gmail — no setup, no configuration.
TrustScan automatically analyses the message for phishing signals — urgent language, sender inconsistencies, social engineering tactics, and AI authorship patterns.
A trust score badge appears next to the subject line. Red means high phishing risk — do not click any links. Amber means caution. Green means the email looks safe.

TrustScan analyses every Gmail message using GPT, which understands natural language rather than matching keywords. It checks for urgency manipulation, authority impersonation, mismatched sender cues, fake invoice patterns, social engineering language, suspicious embedded links, and AI-written content. Because it reads the meaning of the email, it catches novel phishing attacks — including personalised spear phishing that has never been seen before and has no known signature.
