Elicit
AI research assistant that searches 200M+ academic papers, extracts key findings, and synthesizes literature reviews automatically.
Elicit is an AI research tool built by Ought and launched publicly in 2022 that helps researchers discover and synthesize academic literature at scale. Unlike general AI search tools, Elicit indexes over 200 million academic papers from Semantic Scholar and uses language models to extract structured data - study populations, interventions, outcomes, and effect sizes - directly from paper texts. This enables automated literature review synthesis, systematic review support, and structured comparison of research findings across dozens of studies in a single table view. Elicit is widely used by PhD students, scientists, policy researchers, and medical professionals for rapid evidence gathering without manually reading every paper. The free plan provides 12 credits per month; Plus at $10/month provides 50 credits, with additional credits purchasable on demand.
Key Features
- Searches 200M+ academic papers from Semantic Scholar with AI-ranked relevance
- Structured data extraction - automatically pulls populations, interventions, outcomes from each paper
- Literature review table builder for side-by-side comparison of findings across multiple studies
- Full-text paper search for questions that require reading beyond the abstract
- Systematic review support with inclusion/exclusion criteria filtering
- AI summary of each paper's methodology, results, and limitations
- Export to CSV or Google Sheets for further analysis in external tools
Use Cases
- PhD students synthesizing related work for their dissertation literature review in hours instead of weeks
- Scientists conducting systematic reviews to assess evidence quality across clinical trials
- Policy analysts gathering evidence on specific interventions from peer-reviewed research
- Medical professionals quickly assessing current evidence on treatment options or drug interactions
Pros
- Structured data extraction from papers is unmatched - no other tool automatically pulls outcome data into tables
- Grounded in real academic literature, not web content - dramatically lower hallucination risk
- Free tier with 12 credits/month lets students use it regularly at no cost
Cons
- Coverage limited to Semantic Scholar - misses papers not indexed there, particularly recent preprints
- Credit system makes heavy systematic review usage expensive - large reviews can exhaust monthly credits quickly
- Search quality drops for niche or interdisciplinary topics with limited indexed literature
