Pricing Model
FreemiumChatPDF 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.
FreemiumHumata AI is freemium. The official homepage lists a Free plan at $0 with up to 60 pages and 10 answers, which is enough to test the product on a short document but not for regular use.
The Expert plan is $9.99 per month and includes up to 500 free pages, $0.02 per additional page, 3 users and premium chat support. The Team plan is $49 per user per month, with up to 5,000 free pages, $0.01 per additional page, 10 users included, department- and folder-level permissions, OCR for images and scanned text, and response personalization.
Enterprise pricing for more than 10 users is by contacting sales. Page-based allowances and per-page overage fees mean costs scale with document volume, so teams processing large libraries should estimate page counts before choosing a plan.
