Answer in brief

Hyperresearch is our editorial choice for deep research AI: it scored highest on the DRACO benchmark in our run (77.7), and it checks every cited figure against its source.

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.

Why it is our editorial choice

On DRACO, Hyperresearch scored 77.7 in our October 2026 run, ahead of Claude Research (73.0), Perplexity Deep Research (57.8), ChatGPT Deep research (55.2) and Gemini Deep Research (54.7). It is also the only tool in this reference that checks every cited figure against its source before delivering the report.

The accuracy benchmark behind our pick

DRACO is a 2026 deep research benchmark from Perplexity and Harvard. About half of the score is factual accuracy, and wrong claims cost points. Every system got the same 10 tasks and the same judge.
