Feature 01

πŸ“¬ Physical Mail Scanning

Take a photo of any letter, envelope, or postcard. AI reads the full text using OCR and detects fraud patterns in seconds.

StepWhat Happens
1. Take PhotoCamera captures the letter or envelope β€” no uploading to a server manually. The app handles it automatically.
2. OCR ExtractionGoogle Cloud Vision reads every word on the page β€” sender name, addresses, phone numbers, URLs, account numbers.
3. AI AnalysisClaude AI classifies the content against known scam patterns: fake government agencies, prize notices, Medicare fraud, overdue bill scams, and more.
4. Community Cross-CheckThe sender's phone number or address is checked against our community database of reported scammers.
5. Result DeliveredSAFE / SUSPICIOUS / DANGER β€” with a plain-English explanation of exactly what the threat is and what to do.
🚨 Mail Scan β€” DANGER
⚠️ Scam Mail Detected
Letter from "Social Security Administration" β€” fake agency letter requesting SSN and bank account. Do not call the number listed. Shred this letter.
πŸ€– Claude AI 🌐 Community DB
⚠️ Mail Scan β€” SUSPICIOUS
⚠️ Suspicious Mail
Letter from "National Sweepstakes Bureau" β€” prize claim with upfront fee required. Unusual sender and unverifiable return address. Proceed with caution.
πŸ€– Claude AI
Feature 02

πŸ’¬ SMS Text & Email Scanning

Paste any suspicious message β€” text, email body, or forwarded content β€” and get an instant fraud risk assessment with a plain-English explanation.

Message TypeWhat We Detect
SMS / TextDelivery scams, bank impersonation, gift card requests, "click here" phishing links, prize notifications, fake two-factor codes.
EmailPhishing, spoofed sender addresses, fake invoice requests, CEO impersonation, account compromise notices, subscription renewal fraud.
Forwarded MessagesChain messages, "share this warning" scams, fake news designed to harvest clicks or personal information.
🚨 Text Check β€” DANGER
⚠️ Scam Text Detected
Message from 1-800-555-0199 β€” IRS Impersonation. "Your tax return has been flagged" with a link to a fake IRS portal. Do not click. Delete this message.
πŸ€– Claude AI πŸ”— Cross-Channel
βœ… Email Check β€” SAFE
βœ… Looks Safe
Email from Chase Bank β€” verified sender domain, standard transaction alert format, no suspicious links or requests. No action needed.
πŸ€– Claude AI
Feature 03

πŸ“· QR Code Scanner β€” Quishing Protection

Scan any QR code before you tap it. Quishing (QR phishing) is the fastest-growing fraud vector β€” fake QR codes on parking meters, restaurant tables, and mail are used to steal credentials and payment info. MailShield checks the URL hidden inside before you go anywhere near it.

StepWhat Happens
1. Point CameraOpen MailShield and tap "Check a QR Code." Point your camera at any QR code β€” on mail, a sign, a receipt, a menu, or a screen.
2. URL ExtractedThe URL encoded in the QR code is captured instantly β€” without you navigating to it.
3. AI AnalysisClaude AI analyzes the domain, path, and URL structure for phishing patterns, credential-harvesting redirectors, and known malicious domains.
4. Community Cross-CheckThe domain is checked against our community database of reported phishing sites and malicious URLs.
5. Result DeliveredSAFE / SUSPICIOUS / DANGER β€” before your browser ever loads the page. If it's dangerous, close the app and ignore the QR code entirely.
🚨 QR Scan β€” DANGER
⚠️ Quishing Detected
QR code links to paypa1-secure-login.com β€” domain spoofing PayPal. Credential harvesting site. Do not proceed. Report this QR code to the location where you found it.
πŸ€– Claude AI 🌐 Community DB
⚠️ QR Scan β€” SUSPICIOUS
⚠️ Suspicious QR Link
QR code uses a link shortener (bit.ly) redirecting to an unknown destination. Shortened URLs hide the real destination β€” proceed with caution or avoid entirely.
πŸ€– Claude AI
Why QR codes are dangerous. A QR code is just a URL in disguise. Scammers place fake QR codes over legitimate ones on parking meters, restaurant menus, package delivery notices, and even physical mail. The code looks identical to the real one β€” only the URL inside is different. MailShield checks what's inside before you go anywhere.
Feature 04 β€” Flagship

🚫 Call Blocking & Voicemail Prevention

Known scammers are blocked before your phone even rings. They can't call through, and they can't leave a voicemail. Completely silent protection.

PlatformHow It WorksVoicemail Blocked?
πŸ“± iOSIntegrated with Apple's native call screening system β€” blocked callers hear "number not available" before the call ever connects.βœ… Yes β€” caller never connects
πŸ€– AndroidIntegrated with Android's native call screening system β€” blocked calls are rejected at the OS level with a busy signal.βœ… Yes β€” busy signal prevents most carrier voicemails
ScenarioWhat HappensNotification Fired
Known scammer calls (cached)Instantly blocked before the phone rings. No voicemail possible.πŸ›‘οΈ "Scam Call Blocked β€” No voicemail delivered"
Unknown number β€” AI flags as HIGH RISKCall is allowed through on first contact (AI check runs in real time). Result is cached. Next call from this number is instantly blocked.⚠️ "Scam Call β€” Will Be Blocked β€” cached for next time"
Unknown number β€” AI flags as SUSPICIOUSCall is allowed through. Number is labeled with a warning and monitored.⚠️ "Suspicious Call from [number]"
Community database matchBlocked immediately β€” same as a cached scammer. Community-verified numbers are distributed to all users automatically.πŸ›‘οΈ "Scam Call Blocked β€” Community Database"
How the block list grows: Every HIGH risk call is added to your personal block list immediately. Numbers confirmed by the community are added to a shared block list distributed to all users β€” so the next time that number calls anyone on MailShield Guardian, it's rejected instantly with no AI check needed.
πŸ›‘οΈ Call Blocked
πŸ›‘οΈ Scam Call Blocked
Blocked a call from (602) 555-0134 (known scammer). No voicemail was delivered. This number has been reported by 14 MailShield users.
🌐 Community DB
⚠️ Flagged & Cached
⚠️ Scam Call β€” Will Be Blocked
Call from (480) 555-0177 was HIGH RISK β€” IRS Impersonation. This number is now blocked. It cannot call again or leave voicemails.
πŸ€– Claude AI
⚠️ Suspicious Call
⚠️ Suspicious Incoming Call
Call from (888) 555-0141 flagged as suspicious. Be cautious β€” possible sales or robocall. Number is now labeled and monitored.
πŸ€– Claude AI
iOS note: When CallKit blocks a call at the system level, the app is not notified in real time β€” this is an iOS privacy restriction. Blocked calls appear in your Phone app's recents list with a "Blocked" label. MailShield will show a notification for calls it flags and caches, but cannot show real-time alerts for system-blocked calls on iOS.
Feature 05

🏷️ Detection β€” Where the Intelligence Comes From

Every result shows a detection badge so you always know what intelligence flagged it. No black box β€” complete transparency about why something was marked as a threat.

Detection BadgeWhat It Means
🌐 Community DBMatched against our community database of confirmed scam numbers, domains, and patterns β€” built from trusted sources and verified across the MailShield user network.
πŸ”— Cross-ChannelThe same threat actor was spotted across multiple channels on your device β€” for example, a phone number that appeared in both a scam text and an incoming call. Elevated risk automatically.
πŸ€– Claude AIAnalyzed in real time by Claude AI β€” evaluating message content, sender patterns, urgency tactics, impersonation signals, and known fraud signatures in full context.
What about the ⚑ Auto-Protect badge? Auto-Protect describes how a threat reached you β€” it was caught automatically in the background before you ever saw it, rather than you submitting it manually. Under the hood, Auto-Protect uses the same three detection sources above (Community DB, Cross-Channel, and Claude AI) β€” it just runs silently on your behalf, 24/7.
Multiple badges can appear together. A result showing both 🌐 Community DB and πŸ€– Claude AI means the AI confirmed a threat in real time and it also matches known community patterns. All detection layers always run β€” the badge reflects which signal was strongest.
