Elicit
AI research assistant that screens hundreds of papers against your criteria in minutes.
Docs & PDF
Chat-with-a-PDF is the gateway drug of AI productivity: point a tool at contracts, papers, or manuals and ask questions instead of reading. Under the hood the serious tools chunk, index, and cite — which is what separates a research aid from a confident hallucination machine. Always click the citation.
How to choose
- Study and research material → NotebookLM grounds every answer in your sources.
- Contracts and reports → look for page-level citations (ChatPDF, Chatdoc, Humata).
- SciSpace adds paper-aware context (methods, sample sizes) that generic chat tools miss.
