## Aperçu

WhatLetter is an AI document assistant that lets you photograph a paper, translate it into your own language, and then chat about it in plain words until the details make sense. It was built for immigrant families and older readers who have to deal with medical records, bills, legal forms and official letters they cannot easily read.

## Tarifs et offres

WhatLetter uses a freemium model. The Free tier covers capturing documents, up to 3 documents translated per month and up to 3 chat sessions per month. WhatLetter Plus is $1.99 USD per month, with a yearly option advertised at 16% off, and unlocks unlimited document translations, unlimited chat and access to all supported languages. Voice typing and Telegram integration are listed as upcoming rather than included today.

## Fonctionnalités clés et capacités

- **Snap, scan and understand:** Point your phone or webcam at a menu, bill, prescription or letter and WhatLetter reads the text off the image and prepares it for translation.
- **Translation across 30+ languages:** Pick one of 30+ supported languages, including Arabic, Bengali, Mandarin, Farsi, Hindi, Korean, Spanish, Tagalog, Urdu and Vietnamese, and read the paperwork in the language you think in.
- **Conversational follow-up chat:** After translating, you keep chatting with the assistant to ask what a term means, what a date implies, or what you are being asked to sign.
- **Plain-language summaries:** Long and technical material, from insurance paperwork to academic or financial reports, gets condensed into a summary you can actually finish reading.
- **Privacy-first handling:** The site says document images are not retained on its servers and that chat history is kept only for your own reference.

## Cas d'usage principaux

- **Help a parent understand official mail (Caregiver or family member):** Medical records, prescriptions, insurance letters, bills and bank statements get summarised and translated so a patient or caregiver can act on them without relying on a bilingual relative.
- **Decode paperwork while abroad (Traveller):** A ticket, menu, form or schedule encountered on a trip can be photographed and explained in your language on the spot.
- **Summarise a long technical document (Student or analyst):** A student or researcher drops a dense paper or financial report into WhatLetter and reads a condensed, translated version before deciding what to study in depth.
- **Understand a form before signing it (New resident):** Legal forms, benefit applications and residency paperwork get translated and explained so the applicant knows what is being asked before signing.
