Point your camera at a page you can't read and hear what it says out loud, in your own language, in about twenty seconds. Translate, scan, chat, study, listen โ€” and read whole documents in two languages at once. All in one quiet app. โ€” INSTANT NARRATION โ€” A menu in Rome. A form in Tokyo. A page from a book you can't read. Point the camera, tap once, and LingoFile reads the whole page and tells you what it says โ€” out loud, in your language, the way a friend would explain it, not word by word. Pick the language you want to hear it in, or let your phone decide. โ€” BILINGUAL READER โ€” Open a foreign-language PDF, DOCX, or TXT and read it the way you always wished you could: each original paragraph on top, its translation right below. Prefer columns, or translation only? Switch layouts anytime. Tap any word for its meaning, its pronunciation, and an example sentence. Turn on Focus mode and translations stay hidden until you tap โ€” so you try to understand it yourself first. Pick any of 20 target languages, and listen to the same document as a podcast right from the reader. โ€” DOCUMENT TRANSLATION โ€” Drop a PDF, DOCX, or TXT and pick a target language. We translate with neural engines and rebuild the file with the original design preserved. Tables, columns, headers โ€” they stay where they belong. โ€” CHAT WITH YOUR DOCUMENTS โ€” Open a PDF, Word, or text file and just ask. "Summarize this," "what does this section say?", "what are the numbers?" Lingo answers in your language and cites the exact page each answer came from โ€” tap a citation to jump straight there. โ€” AI STUDY CARDS โ€” Turn any document into a deck of question-and-answer study cards, written for you from your own PDF, paper, or textbook. Choose 20, 40, or 60 cards, or let LingoFile size the deck to your document. โ€” AI DOCUMENT SCANNER โ€” Snap a paper, receipt, contract, or whiteboard. Our AI vision engine reads handwriting, complex tables, and faded text โ€” even in low light. Multi-page edge detection turns stacks of paper into clean PDFs in seconds. โ€” AI PODCAST STUDIO โ€” Pick a document, choose 3, 7, or 12 minutes, and turn your reading into a real conversation between two AI hosts. Choose from 8 voices and four styles โ€” Conversational, Academic, News, or Playful. Long documents are covered end to end, not just the first pages. Listen with lock-screen controls, AirPlay, Bluetooth, and live transcripts. WHAT YOU GET โ€ข Instant Narration โ€” point at any page, hear it explained aloud in your language โ€ข Bilingual Reader โ€” translation under every paragraph, in columns, or on its own โ€ข Tap any word โ€” meaning, pronunciation, example sentence โ€” plus Focus mode โ€ข Format-preserving PDF, DOCX, and TXT translation โ€ข Chat with your documents โ€” answers with tap-to-open page citations โ€ข AI study cards โ€” auto-generated question-and-answer decks โ€ข 20 languages: English, Turkish, German, Spanish, French, Italian, Portuguese (BR), Russian, Dutch, Polish, Swedish, Indonesian, Vietnamese, Thai, Hindi, Arabic, Japanese, Korean, Chinese (Simplified & Traditional) โ€ข AI vision OCR โ€” handwriting, tables, receipts โ€ข Two-host AI podcast โ€” 8 voices, 4 styles, 3 / 7 / 12 minutes โ€ข Live transcript, background playback, lock screen, AirPlay, Bluetooth โ€ข One library โ€” searchable, shareable, exportable FREE & PRO Start free: translate your first page and hear one narration a day.
