Consensus vs Perplexity
Features, pricing, strengths and trade-offs — and which one fits your situation.
The verdict
Consensus answers questions only from peer-reviewed research papers, while Perplexity searches the whole web and cites whatever sources it finds. Choose Consensus if you need evidence from scientific studies, want the Consensus Meter to see how research leans on a yes/no question, or plan to export references to Zotero, EndNote or Mendeley for a paper or literature review. Choose Perplexity if your questions cover news, products, companies, how-to topics or anything beyond academic research, or if you want Deep Research reports, Labs and a browser integration. Perplexity has an Academic focus mode, but it is less rigorous than a dedicated paper database, while Consensus is of little use for non-scientific questions. Many students and researchers use both: Perplexity for background and Consensus for the evidence. If you are running a formal systematic review with screening and data extraction, neither is ideal and Elicit is built for that job.
Both Consensus and Perplexity offer a free plan, so you can try each before paying.
