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.
Affordable real-time search API that returns structured JSON plus page content in a single call.
Send a query and receive live web results as clean, structured JSON that is ready for parsing, ranking or feeding into a model.
Convert any URL into clean, readable markdown in the same API key, removing boilerplate so retrieved text is directly usable for RAG and summarization.
Requests are routed across multiple underlying search sources with health monitoring and automatic retries, so a single empty source does not break your pipeline.
Official libraries and snippets for Python, JavaScript, MCP and LangChain make it a few lines of code to add live search to an agent or app.
