Tiers weigh capability, usability, value for money, and how actively each tool is maintained. Every tool publishes its tier rationale and pros/cons, and a weekly re-evaluation moves tiers up or down. The site is ad-funded, so a tier cannot be bought.
Do AI research tools make up papers?
Asking a general-purpose chatbot for papers does produce fabricated citations. Tools that search a real paper database first and summarize second — Elicit, Consensus, Semantic Scholar — carry far less of that risk. Verify by DOI before you cite anything.
Which tool handles analyzing many PDFs at once?
You want a tool that answers only from documents you upload. Check three things: how many documents per workspace, the per-file size cap, and whether answers point back to the source page. Without page-level sourcing, verification costs more time than the analysis saved.
