How does ChatPDF work?
You upload a PDF document and ChatPDF uses AI to analyze its content. You can then ask questions in natural language, and the AI provides answers based on the document text, often with references to specific sections where the information was found.
What types of PDFs work best with ChatPDF?
ChatPDF works well with text-based PDFs including academic papers, reports, contracts, manuals, and ebooks. It handles scanned documents with OCR but works best with native text PDFs. Complex tables and images may have limited understanding.
Is ChatPDF free to use?
Yes, ChatPDF offers a free plan that allows 2 documents per day with up to 120 pages and 10MB per file, and 20 questions daily. No account is required to start. The Plus plan removes these limits.
Can ChatPDF handle multiple documents at once?
With a free account, you can create collections of related documents and ask questions across them. This is useful for research projects or comparing multiple reports on similar topics.
How accurate are ChatPDF answers?
ChatPDF provides answers based on document content and includes source references you can verify. Like all AI tools, it may occasionally misinterpret complex content, so important information should be verified against the original document.
