🧠 Transparent smart processing
These tools use extractive ranking, document retrieval, font structure and pattern analysis. They do not pretend to be a generative chatbot and do not invent facts that are not in the PDF.
💡 Tip
Clean, searchable PDFs give the best results. Very long files are limited by the current free-server page cap.
