FAQs
What is the best AI tool for researchers?
NotebookLM is strongest for interrogating a controlled source set. Elicit, Consensus, and Scite are better specialist candidates for literature discovery and evidence context.
Can AI-generated citations be trusted?
No citation should be accepted without opening and checking the original source, authorship, publication details, quotation, context, and relevance.
How should researchers disclose AI use?
Follow the relevant institution, journal, funder, and discipline policy. Keep a reproducible record of material AI assistance and never list an AI system as an author.
