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.
FreemiumScholarcy is freemium. The Free plan costs $0 and allows up to 10 summaries (one per day with the Article Summarizer), imports in multiple file formats with an 11MB file limit, and lets you export flashcards one at a time.
The paid Monthly plan is $9.99 per month with a 7-day free trial and can be cancelled anytime. The yearly plan, Scholarcy Plus, gives about a 25% discount (roughly $90 per year, or $7.50 per month). Paid plans include unlimited summaries, enhanced summaries, saved flashcards, notes and highlighting, collections, exports of up to 100 flashcards, Literature Matrix creation, bibliographies and a 50MB file limit.
Institutional and academic site licences are available on request, and subscriptions are billed monthly or yearly only.
