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.

Turn your documents into a graph your AI agents can actually cite
Upload documents, URLs, notes or code and let the platform handle parsing, OCR and chunking automatically.
Extract entities, concepts, evidence, relationships and claims into a graph where every node traces back to a source.
Bundle a graph into a versioned, reusable pack you can share with your team or sell in the marketplace.
One MCP server lets Claude, ChatGPT, Cursor, Codex and other clients query the same graph.
