When the World Shakes,
Trinetra Sees the Truth.
A free, live multi-hazard map — evacuation zones, fire perimeters, wind, flood gauges, open shelters — and an AI-assisted home-hardening check. Built by a nonprofit, for the people who live where the hazards are.
The Reality
Chaos is the Enemy.
In the first hour of a disaster, information scatters across a dozen agency sites. Most apps tell you something happened. Trinetra shows the official evacuation zone you are in, the nearest open shelter, and which way the wind is pushing a fire — and, on the other 364 days, what to fix at home before the next one.
Free. No signup. Official orders always come first.
The Architecture
The Power of Trinetra
Watcher agents pre-screen the federal feeds around the clock. People decide.
The Outer Eye (Watcher)
16 hazard feeds on one map — earthquakes, wildfires, floods, and more — refreshed every few minutes. Built on public data from USGS, NWS, NIFC, NOAA, FEMA, and Cal OES (no affiliation).
The Inner Eye (Coach)
On-device AI coach (Coach Kai) delivers personalized preparedness guidance. Before/During/After checklists for every hazard type.
The Third Eye (Truth)
An AI-assisted home-hardening checklist (Berkeley EMBER / NFPA 1144). Every submission is hash-chained on an append-only ledger — advisory, not a certified inspection.
Offline? The map still works.
The hazard map, Coach Kai, and your inspection draft are cached on your phone and keep working without a connection. An SOS you send offline is queued and delivered the moment any connection returns — cellular, Wi-Fi, or satellite-to-phone service where your carrier offers it.
Phone-to-phone relay for the last stretch when nothing else connects is in research, not yet available. It will depend on other Trinetra users nearby and is not a substitute for your phone’s built-in satellite SOS. We’ll say it works when we’ve measured it.
SOS_QUEUE: SENDS ON RECONNECT
P2P_RELAY: IN RESEARCH
Evidence you control.
Every home-hardening walk is recorded on a hash-chained, append-only ledger. Photos stay on your phone; a fingerprint (hash) of each one is anchored so it can later be shown unaltered. Sharing an actual photo — with an inspector, or with your insurer — is your explicit choice, never the default.

What’s built today
The live hazard map is free and open to anyone, anywhere in the United States, with no signup. The home-hardening tools are built against Berkeley’s EMBER defensible-space standard and NFPA 1144 — the codes, not a city partnership. We have no agreement with any city, fire department or insurer today.

Wildfire, earthquake, flood, hurricane, extreme heat and more — each with a checklist and the questions people actually ask.
Will your insurer credit the work?
California rules give you specific rights on proof, deadlines and per-factor discounts. Most homeowners are never told about them.
Ask your AI assistant
Our hazard data is a public, read-only API. Prompts that let any assistant read live evacuation zones, fire perimeters and shelters.
