2. Elicit

Elicit stands as an AI research assistant for academic workflows, processing over 125 million academic papers claiming around 90% accuracy. Developed by Ought as a public benefit corporation, this tool offers AI tools for literature reviews through process-based architecture that prioritizes reasoning over simple text generation.

Key features that drive adoption

• Smart paper discovery across 125+ million academic papers using natural language queries without exact keyword matching
• Automated data extraction into structured tables with customizable columns for systematic analysis
• AI-powered summarization generating paper summaries specific to user questions with built-in source verification
• Systematic review workflows providing guided processes for search, screening, extraction, and report generation
• Seamless integration with Zotero and other reference management tools through RIS, CSV, and BIB exports

Pricing

Basic plans start free with 4 papers monthly for chat/summaries, scaling to $49/month for Pro users requiring 2,400 annual PDF extractions. Team plans at $79/seat/month support collaborative research with pooled resources and admin controls.

Strengths and limitations: Elicit excels in empirical research domains like biomedicine and machine learning, achieving approximately 90% accuracy with transparent source attribution. However, it's less effective for theoretical research and can overwhelm new users with its feature-rich interface. The credit system occasionally confuses users, and pricing can be steep for individual researchers.

Pricing

Completely free forever with optional community support contributions ranging from $3-15/month. No premium tiers or feature restrictions, funded through voluntary user support.

Strengths and limitations: ResearchRabbit's unique visualization approach and collaborative features receive consistently positive user feedback for time-saving paper discovery. The completely free model supports research equity globally. However, reliance on Microsoft Academic Graph limits recent papers (post-2021), and the feature-rich interface can initially overwhelm new users.

Target audience: Academic researchers, graduate students, research teams, and librarians focusing on exploratory research and collaborative literature mapping.

6. Consensus

Consensus revolutionizes research synthesis by analyzing findings from 200+ million papers to provide evidence-based answers rather than simple paper lists.
