AI academic search engine for peer-reviewed science
Ask a research question in plain language and get answers synthesized from peer-reviewed studies, with each claim linked to its source paper.
A visual summary shows how the scientific literature leans on a yes/no question, indicating agreement, disagreement or mixed evidence.
Narrow results by study design, sample size, journal quality, publication year and more to prioritize high-quality evidence.
Aggregate findings across many studies into structured summaries that map what is known and where the gaps are.
