Frequently Asked Questions
How does the AI understand my PDF?
The AI extracts and indexes all text from your PDF. When you ask a question, it finds the most relevant sections and uses them to generate an accurate answer, always citing the page number.
Which AI models are available?
You can choose from Gemini 2.5 Flash (fastest), DeepSeek V3.1 (best value), or GPT-4.1 Nano (most efficient). All models are very affordable.
Is my document data secure?
Yes. Your PDF is processed in memory and never stored permanently. Chat sessions expire after 1 hour. No human ever accesses your documents.
Does it work with scanned PDFs?
This tool works best with text-based PDFs. For scanned documents, use our OCR tool first to extract the text, then chat with the resulting PDF.
