Hyperresearch does the research and shows the evidence. Ask a question, get a cited report; each cited claim is checked against its source, and all sources are kept in a searchable vault. On the DRACO benchmark, we are the world's number-one research agent. New: Answers MCP and API. Your agent calls ask and gets a short answer with word-for-word quotes, or a simple "not found" instead of a hallucination. We combine 4 AI search engines and 40+ other data sources for the widest and deepest access.
