Whatletter

Whatletter is an AI-powered mobile and web application designed to help users understand and engage with written content in any language. By allowing users to snap a photo, upload a file, or paste text, the tool quickly translates documents and enables interactive, conversational exploration of the content. Its primary purpose is to make foreign-language materials—from everyday items to formal documents—accessible and easier to discuss and understand in context.

Beyond basic translation, Whatletter supports natural, back-and-forth dialogue about the text, so users can ask follow-up questions, clarify ambiguous phrases, or request summaries and explanations. The tool handles a wide range of document types, including menus, letters, forms, notices, and educational materials. It preserves layout context where possible, helping users see where each translated passage appears in the original document. Additional capabilities may include extracting key points, simplifying complex language, and adapting explanations to different levels of understanding.
