ChatPDF vs Humata

Both are chat-with-PDF tools with different billing models: ChatPDF's free tier allows 2 documents per day with no account required (its Plus tier promises unlimited document analysis, but the official site does not list the Plus price — the widely reported 2026 figure of $19.99/mo or $139.99/yr is marked 'not verified'), while Humata bills per page — Free covers 60 pages/mo, Expert $9.99/mo covers 500 pages, Team $49/user/mo covers 5,000 pages with OCR and permissions. Choose by monthly reading volume, not by brand. No documents were run through either tool, so no quality ranking is claimed.
