Understand documents across languages

Free Translate PDF

Translate every extracted page into a searchable reading-copy PDF, build a side-by-side bilingual copy, or create cited summaries and reviews with terminology control. Your documents stay in a private temporary session for up to 20 minutes, then are deleted automatically.

Choose PDFs to understand

Add one document or compare several. Scanned pages are read with OCR automatically.

No artificial document, page, file-size, or word limits

How it works

  1. Choose PDFs in any supported OCR language and control the source scope
  2. Select the target language, register, terminology, and translation or bilingual output
  3. Download every translated page as a tagged PDF, or inspect cited insights and refine them with follow-up questions

Private, temporary context

Open-source processors extract text inside a private temporary workspace. Only selected passages are sent to OpenAI with response storage disabled; if OpenAI fails, Bookify uses its private Ollama fallback. Close the session to delete it immediately; otherwise it expires automatically after 20 minutes.
