Elicit is an AI research assistant designed for academic and scientific researchers, providing semantic search across 138 million academic papers and 545,000 clinical trials
A genuinely useful research assistant for finding, summarizing, and extracting data from academic papers, especially for literature reviews and systematic screening. It draws mainly from Semantic Scholar so coverage has gaps, and outputs still need expert verification before you trust them.

02
Perplexity AI is an AI-powered answer engine that searches the web in real-time and provides cited, verifiable responses to user queries
Perplexity answers questions with cited, real-time web sources, making claims far easier to verify than a bare chatbot. Excellent for research and quick fact-finding, though answers can still be shallow or wrong, so it complements rather than replaces deeper reading.

03
Consensus is an AI-powered academic search engine that allows researchers to search and analyze over 200 million peer-reviewed research papers
Best for quickly seeing what peer-reviewed studies actually conclude on a research question, with claims tied to real papers instead of invented citations. The caveat is coverage skews toward biomedical and empirical fields, so it is weaker for humanities or very new topics.
