Know what to do about the weather.

We connect live weather to what you care about and advise before you ask — for people, organizations, and the software you build.

Free on the web. iOS and Android in beta.

Products

Read the weather, have it watched for you, or build on it.

App

The weather, in a sentence.

Every location opens with a plain-language read of now and tonight, then the NWS alerts in effect, live radar, and the hourly and multi-day forecast. When rain is coming in the next hour, it says when. Free on the web with no account; iOS and Android in beta.

Weather agent

A meteorologist on staff.

Tell it what you're planning and what weather breaks it. It turns that into a forecast plan, watches your thresholds against live weather, and briefs you before the weather arrives, citing the forecast and alerts it used. Running an operation? It learns your sites and thresholds the same way. Early access — talk to us.

Talk to us
  • Learns your plans in one conversation
  • Watches your thresholds against live weather
  • Briefs you before the weather arrives
  • Answers questions from live forecast and alerts

Developer platform

Weather your software can reason with.

The data plane our agent runs on, over REST or a hosted MCP: probabilistic forecasts, radar-tracked storm cells, lightning, the best window for an activity, and published forecast skill. An agent can sign itself up and mint a key. Free to start with no card, or pay per call with x402.

  • Hosted weather MCP (36 tools)
  • REST API
  • Agents sign themselves up
  • Free to start, no card
  • Pay per call with x402

Research

A forecast is a claim. Advice is a claim. We grade both.

Forecast analysis

How the models we ingest score against NOAA analysis.

We do not train a forecast model. We ingest the National Blend of Models, HRRR, RRFS, and GFS, serve a priority blend (NBM first), and publish each source model's skill against NOAA analysis — URMA for the surface, MRMS Multi-Sensor QPE for rain. The blend we serve is not a row on the page.

Weather Bench

How well the weather agent decides for real operations.

Forecast skill asks whether the air was right. Decision skill asks whether the call was right. A model can nail tonight's temperature and still tell a campground to stay open. Weather Bench, still being built, grades the weather agent we are building for operations.

  • Same method as software agent evals, applied to operational weather.
  • Real past weather from public NOAA archives. Sealed: only what was knowable at the time.
  • Fixed-rule graders, newest events held out, a human meteorologist baseline planned.

Results publish when the first full run is scored.

Ready when the weather changes.

Build on the data plane, put a weather agent on watch, or open the public app. Running an operation? Start with one message.
