The Best AI Research Tools for Students
AI research tools do three jobs for a student: find papers, make sense of them, and keep the citations straight. The ten picks here cover that whole workflow — cited-answer search (Consensus, Perplexity), pure paper search (Semantic Scholar), summaries and PDF chat (Elicit, SciSpace, Paperguide), visual literature maps (ResearchRabbit, Connected Papers, Litmaps), and Zotero for the bibliography. Prices and limits are read off official pricing pages wherever we can confirm them; when a cap is unconfirmed, we say so instead of guessing. Semantic Scholar is free with no paid tier at all, and Zotero charges only for extra cloud storage. And Perplexity's Education Pro verifies through SheerID with any email address, so you don't need a .edu to get the student rate.
