ChatPDF

Chat-based document workspace for asking questions of PDFs and organising research conversations.

Upload a document, ask a narrow question, and verify the response against the relevant passage in the source.

Access and pricing: The official site advertises free access and Plus upgrades. Exact file, page, and question allowances were not confirmed from readable pricing content.

Current pricing and recurring usage limits could not be fully confirmed. Check the provider’s latest terms before choosing a plan.

What it does well

Based on ChatPDF's homepage, you can summarise, compare and ask questions about PDFs, with answers linked back to the source content. It also offers PDF translation and a side-by-side viewer, which makes checking an answer against the original page straightforward.

Who gets the most from it

Students, researchers and professionals who need to pull answers out of long documents without reading every page. Core features work without an account, and a free account adds saved history and multi-document chats.

Limits to check before you commit

The homepage states the free plan analyses 2 documents per day. Plus is described in the FAQ as providing unlimited document analysis and more advanced features, but the page lists no prices or specific features, and no pricing page was found at /pricing (404). Per-file page and size limits were not confirmed. Verify any answer against the cited passage, and avoid uploading confidential documents until you have read the provider's privacy terms.
