AI-powered protection for mail, texts, emails, phone calls, and payments — plus a live community platform where your neighbors warn each other in real time.
Free unlimited scanning. No account required.
One app. Ten layers of protection — AI scanning, community intelligence, and a live social platform where your neighbors warn each other in real time.
Take a photo of any letter or envelope. Our AI reads it, spots fraud patterns, and tells you exactly what to do in plain English.
Full details →Paste any suspicious message and get an instant risk assessment — IRS scams, bank alerts, delivery hooks, and more.
Full details →Known scammers are blocked automatically — they can't ring through, and they can't leave a voicemail. Completely silent protection.
Full details →Before you send money, gift cards, or wire transfers — verify here first. We catch payment scams before the money is gone.
Full details →Watch over parents or seniors remotely. Get a real-time notification the moment a threat is detected on their device — labeled with their name.
Full details →An animated map showing verified scam activity near you — updated in real time as your neighbors report new threats. See what's circulating in your area right now.
Full details →Read local scam reports, search by type, like and comment — all anonymously. Share a scam you almost fell for in the Confession Booth so others can learn from your experience.
Full details →Your personal fraud score (0–850) grows with every scan, report, and community contribution. Earn Community Defender Badges as you hit milestones.
Full details →Our crowdsourced fraud database grows with every scan across all users. When one person catches a scam, everyone is protected — automatically.
Full details →Background scanning that works 24/7 without lifting a finger. Screens incoming texts and emails and flags threats before you even open them.
Full details →Designed to be simple enough for seniors, powerful enough for everyone.
Take a photo of mail, paste a suspicious message, enter a phone number — or simply turn on Auto-Protect and let the app watch for you.
Claude AI — the most advanced language model available — cross-references fraud patterns against our live community scam database and cross-channel correlation engine.
No jargon. A plain-English explanation of exactly what the threat is, who sent it, and what to do next.
High-risk alerts are pushed to connected family members with the source labeled — "Mom: IRS scam text detected." Scam numbers are automatically added to the block list so they can never call again.
Every notification tells you exactly what was caught, where it came from, and what to do. No guessing.
Other apps block robocalls or filter spam texts. MailShield Guardian is the only app that protects across every scam channel — including physical mail and payment requests — with AI, family alerts, and community intelligence all in one.
