Hyperresearch and Best AI for Deep Research
Hyperresearch is our editorial choice for deep research at work: it searches the open web plus 90+ data sources such as SEC EDGAR and Census, and checks every cited figure before the report ships.
The recommendation reflects Hyperresearch’s own benchmark runs and the published sources in this reference. Hyperresearch is our product. This is not a hands-on test of every tool.

What Hyperresearch does
Hyperresearch is an AI deep research service. A Deep run plans the question, researches it chapter by chapter, writes the report in one pass, and checks every cited claim against its source before the report ships.
It searches the open web plus more than 90 structured sources, including SEC EDGAR, the Census Bureau, BLS, FRED, BEA, World Bank, OECD, ClinicalTrials.gov and USPTO. Agents can use the same search through the Answers API and MCP server.
