Confusing mail?

Take a photo of any letter and get a plain-English answer — what it is, whether you owe money, what to do next, and whether it might be a scam. Built for older adults and the families who help them.

Scan a letter

Point your camera at any piece of mail. The app reads it with on-device OCR — nothing is uploaded.

Know what to do

See the type of mail, whether money is owed, the deadline, and the recommended next steps — in plain English.

Spot warning signs

The app flags scams, pressure tactics, and mismatched senders — and confirms when a sender is genuinely legitimate.

Get help fast

Call or text a trusted family member in one tap, or reach the right fraud hotline if something looks wrong.

Your mail never leaves your phone.

Reading, understanding, and storing all happen on your device. We don't upload your letters and we can't see them. No account is required to start — just open the app and scan.

It understands the mail that matters

From everyday bills to the letters that try to trick you — sorted into a clear risk level so you always know how worried to be.

Normal — looks fine
Caution — verify first
High Risk — suspicious
  • Bills
  • Insurance notices
  • Healthcare & Medicare
  • Bank & financial
  • Tax & property
  • Legal notices
  • Debt collection
  • Utility notices
  • Government-style letters
  • Subscriptions & renewals
  • Marketing & offers
  • Suspicious / scam mail

For bills, it pulls out the amount due and the deadline, and lays out numbered steps. For anything suspicious, it explains why and what to do instead.

Scam & elder-fraud protection

Stops the scams that target older adults

What's This Mail recognizes 80+ scam patterns in English, Spanish, Vietnamese, Tagalog, and Arabic — gift-card and wire-transfer demands, fake IRS and Social Security letters, prize and lottery fraud, tech-support and QR-code phishing, and more.

  • Confirms known-legitimate senders (IRS, SSA, Medicare, USPS, VA, FTC) and shows their real phone numbers.
  • Warns when a bill's amount looks unusual, or when several suspicious letters arrive in a short window.
  • One-tap FTC fraud report and ready-to-send complaint text.
  • An "I already responded" recovery guide with the exact agencies to call.
On-device AI

Private intelligence, right on the phone

The analysis runs on a small AI model built into the app — Qwen 2.5 on iPhone and the device's built-in Gemini Nano on supported Android phones. No servers, no internet required, no data collected.

  • Works offline — on a plane, in a basement, anywhere.
  • Answers in your language and explains things simply.
  • A built-in rules engine always provides a safe answer as a backup.

Questions, answered

What does What’s This Mail do?

You take a photo of a confusing letter and the app explains it in plain English: what kind of mail it is, whether money is owed, the due date, what to do next, and whether it looks like a scam. It is built for older adults and the family members who help them.

Is my mail private? Does anything get uploaded?

Nothing is uploaded. All reading and analysis happen entirely on your phone — the photo, the text, and the AI result never leave the device and we never see them. No account is required to start, and your saved letters are stored encrypted on the device.

How does it understand the letter — does it need internet?

No internet is required. On-device OCR reads the text (Apple Vision on iPhone, ML Kit on Android) and an on-device AI model explains it: Qwen 2.5 on iPhone and the built-in Gemini Nano on supported Android phones. If the AI model isn’t available, a built-in rules engine still gives a safe answer, so it works offline and on a plane.

Can it catch scams aimed at seniors?

Yes. It recognizes 80+ scam patterns — gift-card and wire-transfer demands, fake IRS/Social Security/FBI letters, prize and lottery fraud, tech-support and QR-code phishing, and more — in English, Spanish, Vietnamese, Tagalog, and Arabic. It flags High Risk mail, confirms known-legitimate senders, shows official fraud hotlines, and includes an “I already responded” recovery guide.

Is it easy for an older person to use?

It is designed senior-first: read-aloud with adjustable speed, large and extra-large fonts, high-contrast mode, full VoiceOver/TalkBack support, plain language with no jargon, and a one-tap button to call or text a trusted family member.

What languages does it support?

The app interface is available in English, Spanish, Vietnamese, Tagalog, and Arabic. It reads mail (OCR) in 10+ languages, and the AI answers in the language you choose.

How much does it cost?

It’s free to start with no credit card — you can run real scans before deciding. What’s This Mail Plus unlocks unlimited scans and deadline reminders, and a Family plan covers several relatives. Prices are shown in-app and on the App Store and Google Play.

Which phones does it work on?

iPhone on iOS 17 or later, and Android 12 or later. The generative AI uses the built-in Gemini Nano on capable Android phones (such as Pixel 8 and newer, Galaxy S24 and newer); other phones use the private on-device rules engine instead.

Does it give legal, medical, or financial advice?

No. It helps you understand a letter and decide what to do, and it always encourages verifying with the real sender or a trusted person. It is independent and not affiliated with Medicare, Social Security, the IRS, USPS, AARP, or any agency or insurer.

Can I keep and organize my mail?

Yes. Every scan is saved to a private, searchable archive grouped by urgency, with a bill calendar, due-date reminders, per-letter notes, on-device Q&A, and export to PDF, CSV, or JSON. You set how long data is kept, and you can delete everything with one tap.
