Perplexity
AI-powered answer engine that searches the live web and cites every source
AI research assistant that searches, summarizes and extracts data from 138 million academic papers
Elicit is an AI research assistant that searches over 138 million academic papers and auto-generates structured, cited reports. The free tier allows unlimited paper search and 2 automated reports per month. Paid plans start at $49/month (Pro), which unlocks systematic review workflows screening up to 5,000 papers and 144 reports per year. Best for researchers, analysts and scientists who need rigorous literature reviews without manual screening.
Elicit is an AI-powered research assistant built specifically for academic and scientific literature. It searches a corpus of over 138 million papers, then automatically generates structured research reports backed by sentence-level citations. Unlike general-purpose AI chatbots that may hallucinate sources, Elicit grounds every claim in a retrievable paper — users can click through to the exact sentence that supports each finding.
The core workflow is built around a research question rather than a keyword search. Users type a question, Elicit retrieves the most relevant papers, and then lets researchers add extraction columns — pulling specific data points (sample sizes, outcomes, methods) from each paper into a structured table. The systematic review feature extends this to bulk screening, enabling teams to apply inclusion/exclusion criteria across thousands of papers in a fraction of the time a manual review would take. Elicit also offers research alerts that notify users when new papers matching a topic are published.
Elicit is designed for people who need rigorous, evidence-based answers from the published scientific record — not just a quick summary from an AI chatbot. It is most valuable when the volume of relevant literature makes manual screening impractical.

| Sentence-level citations make it straightforward to verify every claim | 2 reports/month on the free tier is restrictive for active researchers |
| Systematic review workflow provides structured screening comparable to manual methods | Pro plan ($49/mo) is expensive relative to general-purpose AI search tools |
| Free tier is genuinely functional for lightweight research tasks | Report quality depends on what is published; gaps in literature are not flagged |

Yes. API access is included in the Pro plan ($49/month) and above, allowing teams to embed literature-review and data-extraction functionality into their own tools.
Elicit provides sentence-level citations for every claim, so results can be verified against source papers. Accuracy depends on what is published in its indexed corpus; it is not a substitute for domain-expert review.
Both search academic literature with AI. Elicit emphasises bulk data extraction tables, systematic review screening workflows, and report generation at scale. Consensus focuses more on quick consensus-finding across studies on a specific question.
