WhatLetter is an AI-powered document translation tool designed to help immigrant families, seniors, and travelers understand important paperwork in their native language. Users can snap a photo of any document—such as medical records, bills, bank statements, legal forms, or complex technical papers—and receive instant insights, summaries, and translations. The tool also features a chatbot that can answer questions and provide explanations in over 30 languages. Privacy is a priority: uploaded images are processed locally and not saved on servers, and chat history is retained only for user reference. WhatLetter offers a free tier with limited usage and a paid subscription (WhatLetter Plus) for unlimited access.
