Mail Decoder
Explain Official Mail Offline
Free · Designed for iPad. Not verified for macOS.
Point your camera at any confusing letter and get a clear, private explanation in seconds — the action, the deadline, the money. All on-device. Nothing leaves your phone.
Official mail can be confusing and stressful — IRS letters, immigration notices, benefits paperwork, medical bills, legal forms. Mail Decoder turns intimidating mail into a clear, plain-language explanation, completely on your phone.
Just point your camera at the letter. Mail Decoder reads it and tells you, in plain language:
• What the letter actually means
• The exact action you need to take
• Any deadline you need to meet
• Any amount of money involved
100% PRIVATE — NOTHING LEAVES YOUR PHONE
The photo, the text recognition (OCR), and the AI that explains it all run entirely on your device using Apple Intelligence. Your letter, its contents, and the explanation are never uploaded, stored on a server, or shared with anyone. Mail Decoder works fully offline and needs no account.
BUILT FOR REAL LIFE
• Great for limited-English households — understand mail in clearer language
• Help an aging parent or relative make sense of official letters
• Never miss a deadline or a payment hidden in dense paperwork
• No subscription, no sign-up, no tracking
HOW IT WORKS
1. Open Mail Decoder and point the camera at the letter
2. It reads the text on-device and explains it in plain language
3. See the action, deadline, and money at a glance
4. Ask a follow-up question if anything is still unclear
IMPORTANT
Mail Decoder provides general, informational explanations to help you understand your mail. It is not legal, tax, immigration, financial, or medical advice, and it is not a substitute for a professional. Always verify important details and consult a qualified professional for decisions that matter.
