Feature Comparison
In-Depth Analysis
Elicit and Perplexity are both AI research assistants, but they are tuned for different kinds of research. Elicit is purpose-built for academic literature. It searches a database of over 125 million scholarly papers, extracts specific data points—methods, sample sizes, findings—into structured tables, and is designed to accelerate systematic reviews and literature surveys. For students writing a thesis or reviewing primary research, Elicit's paper-centric workflow is hard to beat.
Perplexity is a general AI search engine. It answers questions by synthesizing current web sources with inline citations, covering news, general knowledge, and academic topics alike. It is faster and broader for everyday research questions, and its Pro and academic-focused modes can also surface scholarly sources, but it is not specialized in extracting and comparing data across dozens of papers.
For a literature review, systematic comparison of studies, or extracting findings from many papers at once, Elicit is the specialist tool. For quick, well-cited answers across the broader web—or as a first step before diving into the papers themselves—Perplexity is faster and more versatile. Graduate students often use Perplexity to scope a topic and Elicit to do the rigorous paper-level work.
