Elicit

Literature review from papers — extract, compare, and do not pretend it read the PDF for you.

8.1/10Best paper literature reviewUpdated September 19, 2026

The Aiacent take

Elicit is the research tool we would hand someone who has to review a literature, not a landing page. You ask a question. You get a table of papers. You extract methods and findings into columns. That is a real 2026 job, and it is not Perplexity.

We ranked it second on the research page because most 'AI for research' tickets are still a cited-web ticket (Perplexity) or a 'help me think' ticket (ChatGPT). Elicit wins when the sources have to be papers. Consensus wins a faster yes/no from the same corpus. Mixing those up is how a grad student buys Plus and still pastes abstracts into ChatGPT.

Skip Elicit if you will not open the PDFs. A prettier table of hallucinations is still a hallucination. Skip it if the job is a competitor brief — that is Perplexity.

Most 'we need AI for research' tickets from a lab are an Elicit ticket. Most from a startup are a Perplexity ticket. The word research is doing too much work.

Pros

  • The table of papers is the product — columns you asked for, not a chat dump
  • Faster than opening forty PDFs when the job is 'what has been tried'
  • Upload and extract is useful when the corpus is already on disk

Cons

  • It will still miss a paper, misread a method, and flatten a caveat. You still read
  • Not a writer. The output is a research table, not a grant or a blog
  • Wrong default if the question lives on the public web, not in journals

Who it's for

  • Researchers, analysts, and operators running a literature pass
  • Teams that already have a pile of PDFs and needed extraction
  • Anyone whose Perplexity habit is 'search Google Scholar in a chat'

Who should skip it

  • People who needed a cited web brief (Perplexity)
  • People who needed a draft, a memo, or a grant (ChatGPT or Claude)
  • People who will not click through to the paper

What matters in the product

Paper table

The product. Columns you define. If you wanted a paragraph, you are in the wrong tool.

Extract from PDFs

Useful on a corpus you already trust. Garbage uploads produce confident garbage.

Screening

A first pass. You still decide inclusion. An AI that 'finishes the review' is how bad reviews ship.

Verdict

The literature-review desk. Buy Elicit when the sources have to be papers. Buy Perplexity when the sources are the web. Do not buy it as a writer.
