Got a letter you can't read? TransLex translates it and explains what it actually means. Point your camera at a letter, or upload a PDF, and TransLex gives you the full translation plus a plain-language summary: what the document says, what you need to do, and any deadline you must not miss. TEXTBOOKS, PAPERS AND WHOLE BOOKS Upload a 200-page PDF and get it back in your language, formatted like the original. Studying? Ask for a summary, a plain-language explanation or a key-terms glossary. The free plan translates the first ten pages of any document; Premium translates all of it. WHAT MAKES IT DIFFERENT Most translation apps hand you the words and stop there. TransLex also tells you what to do with them. Choose the kind of document you are holding and the explanation is written for that situation: • Government letters — tax, immigration, licensing, benefits, city and utility notices • School letters — permission forms, fees, what your child needs • Medical and lab results — every term explained in everyday words • Leases and landlord notices — rent, deadlines, notice periods, deposits • Insurance letters and claim decisions — what is covered, what was decided, how to respond • Contracts and agreements — obligations, money, cancellation terms HOW IT WORKS 1. Take a photo of the document or upload a file (PDF, Word, Excel, CSV, images) 2. Choose your language and the type of document 3. Read the translation, the summary, and the list of what to do FEATURES • Camera scan with text extraction — no typing, no copy-paste • Works with PDF, Word, Excel, CSV and photos • Translate into and out of dozens of languages • Your own glossary — keep names and key terms translated the same way every time • Side-by-side bilingual PDF export, so you can hand the document to someone else • Custom instructions — ask for a summary, simpler wording, or a specific tone • Translation history, saved on your device FREE AND PREMIUM Every day you get free translations to use however you like. Need more in one sitting? Watch a short video to unlock another, or subscribe for unlimited translations, all document types and side-by-side PDF export. IMPORTANT TransLex is an AI translation tool for understanding documents. It is not a certified or sworn translation service, and it does not provide legal, medical, immigration or financial advice. For official submissions that require a certified translation, use an accredited translator. Always confirm anything important with the organisation that sent you the document.
