What is ChatPDF?

ChatPDF is a narrow, practical document assistant: drop in a PDF and ask questions in plain language instead of scrolling. Answers cite the page they came from, which is the feature that makes it trustworthy enough for contracts, papers and manuals, and each document gets its own thread so follow-up questions keep context. It handles large files and scanned documents reasonably well, and there is an API for teams that want the same behaviour inside their own tools. The free tier is metered by document count and page limits.

FAQ

Does ChatPDF show where answers come from?

Yes, responses include references to the pages used, which is what separates it from pasting text into a general chatbot. You still need to open the page and confirm, since citations occasionally point to related rather than decisive passages.

What are the limits on the free plan?

Free use allows a small number of documents per day with a page cap per file and some message limits. Paid tiers raise those ceilings, which matters if you work through long reports regularly.

Can it read scanned PDFs?

Text-based PDFs work best. Scanned files depend on OCR quality, and documents that are heavy on tables, charts or unusual layouts often need a human read to be sure nothing is missed.
