Researcher and academic
Papers, literature reviews and citations.
Researchers and academics spend their days finding papers, reading them, extracting findings and managing citations. Elicit, Consensus and SciSpace search the literature and summarise studies, while ChatPDF lets you ask questions of a single paper. The key caution is verification: summaries can misstate results or invent references, so check every claim against the source before citing it.
Questions people ask
Can AI find and screen papers for a systematic review?
It can speed up search and first-pass screening, and tools like Elicit extract study details into tables. It cannot judge study quality or cover papers missing from its database, so record your search method and read the key papers yourself.
Do AI tools make up citations?
General chatbots sometimes do, producing references that look real but do not exist. Research-focused tools that link to indexed papers lower the risk, but you should still open each cited source and confirm the claim appears in it.
Is it acceptable to use AI in academic writing?
It depends on your institution and the journal. Many allow AI for language editing or search with disclosure, while banning it for generating text or analysis. Read the relevant policy, and never list an AI tool as an author.
