Pricing Model
Difference
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.
PaidGenei is a paid product with a 14-day free trial that can be cancelled anytime. There is no permanent free plan. The Basic plan is £4.99 per month or £3.99 per month billed annually, with 5GB maximum file uploads, unlimited projects and resources, AI summaries, keywords, cloud notes, search and chatbot support. The Pro plan is £19.99 per month or £15.99 per month billed annually and adds unlimited file uploads, advanced summarisation, GPT-3 features, multi-document analysis, question answering, and expand, paraphrase and rephrase tools. Academic pricing is also listed, including a Professional tier at £9.99 per month (£7.99 annually) with a 40% academic discount and a higher Pro tier at £29.99 per month (£24.99 annually). Student discounts are available through Student Beans. Prices are in GBP and may change, so confirm on the pricing page.
