❓ Frequently Asked Questions
Can ChatPDF search across multiple PDFs?
ChatPDF's Plus plan supports multi-document conversations, letting you ask questions across several PDFs simultaneously. However, it works with the documents you provide, unlike Consensus which searches its massive database automatically.
Which is better for academic research?
For literature discovery, Consensus is better — it searches 200M+ papers and surfaces relevant research you might miss. For deep analysis of papers you already have, ChatPDF excels. Most researchers use both: Consensus to find papers, ChatPDF to digest them.
Does Consensus let me chat with individual papers?
Consensus recently added the ability to upload and analyze individual papers, similar to ChatPDF. However, ChatPDF's interface is more optimized for deep document analysis, while Consensus is optimized for search and synthesis across many papers.
Are both tools suitable for non-academic use?
Absolutely. ChatPDF is excellent for contract review, legal documents, user manuals, and any long-form PDF. Consensus is useful for evidence-based decision making in business, health, policy, and any field where you need reliable, cited information.
