AI tools for research papers
AI research tools ranked by fit for academic work: finding papers, extracting findings, checking how a claim is cited, and drafting a literature review.
Research tools differ from chat assistants in one way that matters: they search an index of real papers and tie each statement to a source. That is what makes their output checkable.
Use them to find and triage literature faster, not to replace reading. The good ones make it quick to open the passage behind a claim.
