Radar Researcher is a feature of 📝Cloudflare Radar — 📝Cloudflare's public Internet data platform — that turns plain-language questions about Internet traffic into real, interactive charts paired with a short written explanation of what the data shows.
Radar held a decade of measurement data behind chart pickers, location selectors, and an API that assumed you already knew which dataset answered your question. Researcher removes the requirement to understand the schema before you are allowed to ask.
It is aimed at journalists working an outage on deadline, network operators diagnosing regional degradation, academic and human-rights researchers, and newcomers who have a question but no map of the data. Free, in beta, no account required.
This is the clearest public reference implementation of the pattern I keep building toward — natural language over a structured corpus, answering with the real artifact rather than a summary of it, and exposing the reasoning trail so the answer can be audited instead of trusted.
Key Capabilities
- Plain-language querying — Ask by typing or by voice and get back live interactive Radar charts alongside a short written reading of what the data actually shows.
- Explain with AI — An inline button on any existing Radar chart hands that specific visualization to the model for interpretation without leaving the page.
- Auditable reasoning — Every answer exposes how the question was interpreted, which datasets were consulted, and how the stated conclusion was reached.
- Shareable sessions — Chats are saved and searchable, and any session can be shared through a generated link that expires automatically after thirty days.
- WebMCP support — Radar advertises its own tools to general-purpose browser agents, so an outside agent can drive the same datasets a person queries by hand.
Getting Started
- Open any page on Cloudflare Radar and click Researcher in the site header.
- Type or speak a question — "What's Internet quality like in Portugal?" works.
- Read the chart, then open the reasoning trail to see which datasets it used.
- Click Explain with AI on any existing Radar chart to interpret it in place.
- Share a session using the generated link; it expires after thirty days.
