Is that message from Amazon really from them? Did you receive an urgent SMS about an unpaid bill? ScamScan uses advanced AI to detect scams in seconds before you click. HOW IT WORKS Paste suspicious text or upload a screenshot of any message. Our AI analyzes content, links, and visual patterns to determine if it's a scam. Get a risk score from 0-100 with clear explanations and specific next steps. SCREENSHOT ANALYSIS Unlike basic text checkers, ScamScan can analyze images. Upload screenshots of SMS, emails, or DMs directly. The AI checks not just the text but also suspicious logos, layout inconsistencies, and visual phishing attempts that text-only scanners miss. DETECTS ALL SCAM TYPES Phishing scams: Fake Amazon, banking, or delivery service sites asking you to click links Delivery scams: Fake package delivery notifications requiring immediate payment Fake invoice scams: Demands for unpaid services or legal threats Investment scams: Guaranteed returns or get-rich-quick schemes Impersonation scams: Someone pretending to be a friend, family member, or official authority Romance scams: Online dating profiles requesting money Support scams: Fake tech support claiming your device is infected AI-POWERED DETECTION Traditional security apps rely on blacklists that miss new scams. ScamScan uses GPT-class AI to understand context and detect emerging threats. It identifies red flags like urgency tactics, unnatural language, suspicious URLs, personal information requests, and authority impersonation. CLEAR ACTIONABLE ADVICE We don't just say "scam detected." We tell you exactly what to do: Block the sender, ignore the message, verify through official channels, or report to authorities. Each recommendation includes specific steps to protect yourself. WHO NEEDS SCAMSCAN Protect yourself from SMS phishing attacks Help elderly family members avoid grandparent and tech support scams Verify suspicious investment opportunities Check messages before clicking any links Screen messages when something feels off PRIVACY FIRST Your security is our priority. Mask personal information before analysis. We use enterprise-grade encryption and never store your message content beyond necessary processing.
