About ChatPDF
This listing is research-based: I read the official ChatPDF homepage, a third-party pricing page and reviewer videos rather than running my own benchmark. The pitch is simple and it is easy to see why it spread: no account is needed to try it, you upload a file, and the answers cite the passages they came from, with the chat and document side by side for checking. The limits are where the product shows its freemium shape. Two documents a day on the free plan is tight, daily allowances do not roll over, and the official page does not state the Plus price, so the $5/month figure here is a third-party report that you should confirm. Citations help, but any document chat tool can misread tables, scans and complex layouts, so verify anything important against the PDF itself. For students and professionals who occasionally need to interrogate a long paper or report, the free tier plus Plus for busy weeks is reasonable value. If you need deeper research workflows, team permissions or enterprise security, look at Humata, NotebookLM or a research-focused tool instead.
ChatPDF is a document chat tool that works like ChatGPT for your files. You upload a PDF, Word, PowerPoint, Markdown or text file, then ask questions and get answers that cite the passages they came from. A side-by-side view keeps the chat and the document open together so you can check each answer against the source.
Beyond single-file Q&A, it supports multi-file chats organized into folders, summaries of long papers and reports, and translation, so you can upload a document in one language and chat in another. The site also lists an AI writer, an AI detector, YouTube chat, a research mode, flashcards and slides, plus desktop and mobile apps.
It is aimed at students, researchers and professionals who need quick answers from long documents without reading every page. The free tier is small, so regular users will likely move to the paid plan.

Pricing
ChatPDF is freemium. The official site confirms a free plan of 2 documents per day, no account needed to try the core features, and a paid ChatPDF Plus plan with unlimited document analysis, but it does not list a price. The figures below come from a third-party pricing page that says it checked ChatPDF's public pricing in August 2026, so confirm them on chatpdf.com.
Reported Free plan: $0, 2 PDFs per day, up to 120 pages per PDF, 50 questions per day and a 10 MB file limit, with standard answer quality and citations. Reported Plus plan: $5/month, 50 PDFs per day, up to 2,000 pages per PDF, 1,000 questions per day and a 32 MB file limit, with higher answer quality, multi-file chats and priority processing.
Daily limits do not roll over, and uploads on the free plan may not be kept indefinitely, so older chats may need re-uploading.
