Database Size and Coverage
Both platforms connect directly to massive academic indexes rather than scanning the open web like ChatGPT or Google.
Consensus AI claims access to over 200 million peer-reviewed papers. It draws from Semantic Scholar, PubMed, PMC, and other publisher partnerships. This makes it incredibly versatile, covering fields from medicine and physics to psychology and economics. Consensus filters out blog posts, opinion pieces, and non-scientific literature, ensuring you only receive evidence-based research.
Elicit searches through approximately 125 million papers, primarily sourced from Semantic Scholar. While this index is slightly smaller on paper, in practice, both tools cover the exact same core scientific literature. If a major study is indexed in PubMed or CrossRef, both Elicit and Consensus will find it.
The main difference lies in how they present this data: Consensus focuses on indexing papers that directly answer a query, while Elicit prioritizes papers that contain extractable data points.
Search Style and Querying
The way you search on these platforms dictates the initial workflow.
Consensus AI: The Scientific Search Engine
Consensus behaves like Google, but exclusively for science. It is designed to answer direct, yes-or-no questions or relationship-based queries. For example, if you ask: "Does caffeine improve memory?", Consensus will analyze the literature and present:
- The Consensus Meter: A visual breakdown showing the percentage of papers that say "Yes" (e.g., 70%), "No" (e.g., 10%), or "Possibly/Neutral" (e.g., 20%).
- Synthesized Summary: A brief paragraph summarizing the general consensus.
- Direct Quotes: Individual search results with the exact sentence from the abstract that answers your question.
This makes Consensus highly accessible. You do not need to be an academic to understand the results.
Elicit: The Systematic Review Workspace
Elicit is not a simple search engine; it is a workspace. When you enter a query like "What are the effects of caffeine on short-term memory?", Elicit searches the index and creates a structured table.
For every paper found, Elicit sets up columns:
- Paper Title & Authors
- Abstract Summary (synthesized by Elicit's LLM)
- Custom Columns (which you can add based on your research interest)
Elicit excels at multi-step research. It doesn't just give you a quick answer; it builds a database that you can filter, sort, export to CSV or BibTeX, and use as the foundation for a meta-analysis.
Data Extraction: Elicit's Superpower
The absolute differentiator between these two tools is Elicit's data extraction engine.
When conducting a systematic review or writing a thesis, you must read dozens of papers to find specific details. Elicit automates this. You can ask Elicit to extract:
- The sample size used in each study.
- The specific intervention (e.g., dosage of caffeine).
- The population details (e.g., healthy adults, college students, elderly).
- The outcomes measured and the funding source.
Elicit scans the full text of the PDFs (when available) to extract these variables and puts them directly into your table. If Elicit makes a mistake or if you want to verify the context, you can hover over the cell, and it will highlight the exact paragraph in the paper where it found the information.
Consensus AI cannot do this. While Consensus provides a high-level summary and lets you filter by study type (e.g., Randomized Controlled Trial, Systematic Review, Cohort Study), it does not allow you to build custom comparative tables with specific variable extractions.
Custom PDF Uploads
What happens when you already have a folder full of PDFs you need to analyze?
Elicit allows you to upload your own PDFs (up to 100 at a time). Once uploaded, you can run the exact same data extraction queries on your private library. You can ask Elicit to search your PDFs for specific methodologies, find which ones used a particular statistical test, or summarize their conclusions. This is a game-changer for graduate students and professional researchers who have already gathered their source material.
Consensus AI has recently added PDF upload capabilities, but the feature is much simpler. It essentially lets you upload a paper and chat with it using an AI Copilot. It lacks Elicit's ability to extract structured data across dozens of custom PDFs simultaneously into a comparative matrix.
User Experience and LLM Integrations
Consensus AI offers a highly polished, modern interface. It feels familiar and requires zero training. Additionally, Consensus features a GPT-4 powered Copilot. When enabled, the Copilot writes a comprehensive overview of the search results, complete with inline citations. You can ask the Copilot follow-up questions, ask it to draft a paragraph for your introduction, or request that it simplify a complex scientific concept.
Elicit has a steeper learning curve. Its multi-column table interface can feel overwhelming at first. However, it is far more powerful for complex tasks. Elicit also offers a "Concepts" search that helps you map out how different researchers define terms, and a "Find papers that cite this" tool to trace scientific lineage. Elicit's interface is designed for users who plan to spend hours refining their search, rather than those looking for a quick citation.
Pricing and Value for Money in 2026
Both tools offer free tiers, but their limitations are structured differently.
Elicit Pricing
- Free Plan: Gives you a one-time signup bonus of 5000 credits. Once these credits are gone, you cannot perform new searches or extractions unless you subscribe.
- Basic Plan ($12/month billed annually): Provides 2,000 credits per month. Best for casual researchers.
- Plus Plan ($25/month billed annually): Provides 10,000 credits per month, faster speeds, and priority export features. Best for active academics.
Note: Elicit consumes credits based on the complexity of the task. Extracting data from full-text PDFs consumes significantly more credits than a simple abstract search.
Consensus AI Pricing
- Free Plan: Unlimited basic searches. You get 20 Copilot credits per month to run synthesized summaries.
- Premium Plan ($9.99/month billed annually): Unlimited Copilot searches, unlimited Consensus Meter access, bookmarking, and CSV exports.
- Enterprise Plan: Custom pricing for labs and universities.
Consensus is substantially cheaper and more generous with its free tier. If you only need to run searches and get scientific answers, the free plan of Consensus can last you indefinitely.

- You want a simpler search engine: You prefer a Google-like UI that synthesizes answers with an easy Copilot chat.
- You are on a budget: You want unlimited searches without worrying about running out of credits.
FAQ
Do Elicit and Consensus hallucinate references?
No. Unlike standard ChatGPT or Gemini, which can invent academic papers that do not exist, Elicit and Consensus AI search real academic databases (primarily Semantic Scholar). Every citation they provide is a real, published paper with a valid DOI (Digital Object Identifier). However, they can occasionally misinterpret the findings within a paper, so you should always verify the highlighted text.
Can these tools search medical journals?
Yes. Both tools index major medical databases including PubMed and PMC (PubMed Central). They are highly effective for evidence-based medicine, clinical queries, and finding randomized controlled trials (RCTs).
Is there a free version of Elicit and Consensus?
Yes. Consensus offers a free plan with unlimited basic searches and 20 Copilot summaries per month. Elicit offers a free trial with a one-time allocation of 5000 credits. Once Elicit's credits are exhausted, you must upgrade to a paid subscription to continue extracting data.
