On-device AI protection that helps you spot phishing emails and provides advanced email security with email fraud detection. This email scam checker flags phishing scams, fraud, and fake emails directly in your inbox — Gmail, Outlook, Yahoo Mail, and Proton Mail. No message content ever leaves your browser. All scanning runs locally on your device. 100% on-device — nothing is uploaded to any server. 🛡️ Learn how to spot a phishing email Every scam attack follows patterns. How to spot phishing emails is simple once you know what to look for. It teaches you exactly what to identify in each message. Open any message and it immediately scans the sender, content, links, and attachments. A colored badge appears — green for safe, yellow for suspicious, red for scam. Click to see what triggered the alert with clear explanations and the specific text that raised each flag. 🔍 Real phishing patterns detected This advanced detection system runs 24 heuristic checks on every message, identifying patterns used in real attacks: 🔹 Sender impersonation — domains that spoof banks, exchanges, or well-known brands 🔹 Suspicious links — hidden URLs, redirects, and link mismatches 🔹 Urgency language — pressure tactics, threats, and fake deadlines 🔹 Generic greetings — mass attacks use "Dear customer" not your name 🔹 Dangerous attachments — executable files disguised as documents 🔹 Grammar errors — poor language that professional companies never use 🔹 Spoofed anti-phishing codes — mismatched security phrases from your services 🔹 Financial scam patterns — invoice fraud, wire transfer requests, and CEO-impersonation phrasing used in business email compromise (BEC) attacks 📊 Real-time inbox security scanning The checker works automatically in the background. No clicking, no manual checks, no uploading anything. As you browse your inbox, every message gets a risk score from 0 to 100 based on the combined weight of all findings. Positive signals like unsubscribe links and physical addresses reduce the score — genuine messages don't get flagged. 🤖 Advanced AI phishing detection — on-device scanning For deeper detection beyond heuristics, use the built-in AI phishing detection model for advanced on-device analysis. This DistilBERT detector runs entirely on your device via WebAssembly — a one-time 67 MB download, then works offline forever. It provides its own verdict, confidence percentage, and detailed reasoning. With both rule-based detection and AI analysis, you get two independent verification methods in one extension. 🔐 Anti-phishing code verification Services like Proton Mail, Coinbase, Gate, and Binance include a personal security phrase in every legitimate message. Add your anti-phishing codes in the popup. If a message claims to be from your bank or exchange but the code doesn't match — critical red flag. If it matches — green confirmation. No other tool offers this layered verification. ⭐ Why users choose the best phishing protection ➤ 100% local analysis — zero data sent anywhere ➤ Works on Gmail, Outlook, Yahoo Mail, and Proton Mail ➤ Advanced AI-powered phishing email checker with offline capability ➤ Security code matching for banks and exchanges ➤ Real-time email security scanning with immediate visual feedback ➤ No account, no subscription, no data collection 📈 Your security dashboard Open the popup to see your stats — messages checked, threats caught, all-time totals.

The goal is to trick you into revealing passwords, credit card numbers, or personal information — or to install malware. Phishing emails use urgency, lookalike domains, and copied branding. It automatically detects these tactics so you don't have to spot them manually. ❓ Is my data sent anywhere? 💡 No. All analysis — heuristic checks, AI phishing detection, anti-phishing code matching — happens entirely locally. Zero data leaves your browser. ❓ Is this email legit — how can I tell if it's a phishing scam? 💡 Open the message and it automatically scans the sender, content, links, and attachments. A colored indicator instantly shows if it's safe (green), suspicious (yellow), or a scam (red) — the fastest way to check if an email is a scam or tell if an email is real without guessing. ❓ What do phishing email examples look like? 💡 Common phishing email examples impersonate banks, crypto exchanges, or shipping companies with urgent subject lines like "your account has been suspended" or "payment failed — verify now." Real patterns include lookalike sender domains, generic "Dear customer" greetings, links that don't match their visible text, and — for services like Proton Mail, Coinbase, Gate, or Binance — a missing or mismatched anti-phishing code. It recognizes these exact patterns automatically instead of asking you to memorize examples. ❓ Which email providers does it support? 💡 It works with Gmail, Outlook (live and office), Yahoo Mail, and Proton Mail. ❓ What is security code verification? 💡 Banks and exchanges include a personal security phrase in messages. Configure yours in settings, and any mismatch gets flagged as critical. ❓ Is this a real email or a phishing scam? 💡 This protection tool instantly determines if an email is legitimate by analyzing sender, content, and links. It's not just verification — it's full threat detection using 23+ analysis methods. ❓ How is this different from email verification tools? 💡 Email verification checks if addresses exist. This detects phishing content — scams, fraud, impersonation — using 23 rules plus optional AI analysis. ❓ Does it detect business email compromise (BEC) or invoice fraud? 💡 Yes — invoice fraud and wire transfer requests are caught under financial scam patterns, while CEO-impersonation phrasing and reply-to mismatches are dedicated checks. Together they cover how BEC attacks actually work. ❓ Does the AI model need internet? 💡 Only for the first download. After that, it runs entirely offline in your browser. ❓ What to do if I clicked on a phishing link? 💡 Act fast: change passwords immediately, enable two-factor authentication, monitor accounts for fraud. Then use this protection to prevent future attacks. ❓ How do I detect phishing emails? 💡 Look for red flags: suspicious sender, urgent language, mismatched links, poor grammar, requests for credentials. It catches all of these automatically. ❓ How do I recognize a phishing email? 💡 Check the sender's actual email address (not display name), hover over links to see real URLs, look for generic greetings, and watch for urgent requests. The best email security identifies these patterns instantly. ❓ How do I report and block phishing emails? 💡 To report a phishing email, use your provider's "Report phishing" option or forward it to their abuse address, then mark it as spam and block the sender. Better: use an email scam checker that flags phishing before it reaches you — protection works preventively, not after the fact. Get real-time email security and phishing protection with zero data sharing — privacy that actually works.
