Where public signals converge
UnderWalker is a living map of Central Texas — the stretch from Waco and Killeen down through Austin and Bryan–College Station to Houston. It watches dozens of public data feeds around the clock, draws what it finds on a parchment map that updates every few minutes, and writes a plain-English brief of what's happening right now.
Most of what UnderWalker shows exists somewhere in public already — a weather warning here, a river gauge there, a local news story somewhere else. What no single feed shows is when they agree. UnderWalker's job is the joining: when independent public sources point at the same place at the same time — a flood warning, a rising gauge, and local news coverage, say — the map marks the convergence. That mark (the orange ⊕) is the one thing here you can't get anywhere else.
Local news is gathered continuously, grouped so one event reads as one story no matter how many outlets covered it, summarized, and placed on the map when a specific Central Texas location can be identified. A small AI model helps sort which stories are genuinely local and writes the short summaries — every summary links back to the original reporting, and the outlets that did that reporting are credited by name.
The map is honest about what it knows. Official broadcasts (a warning, a flight restriction) are drawn differently from statistical inferences, and everything can be traced back to its evidence. When it's quiet, the map is quiet — an empty layer means nothing is happening, not that nothing is watched.
UnderWalker watches patterns and public institutions, never named private individuals. Every input is something already broadcast publicly by choice, institutional data published for public benefit, or a statistical aggregate that doesn't resolve to any person. No private device locations, no tracking, no surveillance of individuals — that's a hard line, not a preference.
Everything below is free, public data. UnderWalker exists because these institutions publish what they know — credit where it's due.
An underwalker moves through the substrate everyone else stays above. The map doesn't add anything to the world — it shows you what was already there, named and connected. Up from under.
