Available for macOS · Windows & Linux coming soon
Every survival app has the same fatal flaw — they need the one thing you don't have in an emergency. No Signal is different. It runs entirely on your machine. Local AI. Local documents. Local maps. Truly, permanently offline.
A survival-specific AI that runs entirely on your device. No API calls, no cloud, no connection required. Ask in plain language — get step-by-step guidance backed by real documents.
Every answer comes from verified survival documents, and it shows you exactly where. No made-up information — just real knowledge with real citations.
Ask about boiling water without a lighter and it automatically pulls fire-starting methods too. It connects the dots so you don't have to.
Follow-up questions work naturally. Ask about shelter, then say "What about in cold weather?" — the AI remembers what you've been talking about.
Medical, plant ID, and first aid topics automatically display safety banners. The AI tells you when something is dangerous rather than guessing.
Works on older laptops. Runs even better on powerful ones. Detects your hardware at startup and optimizes automatically — no setup required.
Save any AI response to your bookmarks collection. Export entire chat histories with timestamps. Your best answers are always one click away.
Thousands of pages from military field manuals, government survival guides, and expert references — spanning 16 categories. Sources include FM 21-76 U.S. Army Survival Manual, FEMA Emergency Preparedness Guide, and more. Searchable, categorized, and ready for instant offline access. The knowledge of field manuals, distilled and at your fingertips.

No telemetry. No analytics. No phone-home. Zero network calls when offline.
No cloud. No server. The AI brain runs directly on your hardware, GPU or CPU. It never phones home.
Every survival document is indexed and searchable in milliseconds. Ask a question, get the exact passage you need.
Download your region once. Topographic maps stored permanently on your drive. No connection needed, ever.
1,000+ stars pre-loaded with position data. The night sky works without a signal — point up and find your way.
Not "works offline sometimes." Not "cached for a while." This is a fundamentally different architecture.
The AI, the documents, the maps, the star chart — everything runs on-device with zero network. Download it, disconnect forever, it still works.
Not a general chatbot. Responses prioritize actionable, step-by-step guidance. Leads with what to do, not what to read.
Every answer traces back to a real document. No hallucinated advice when your life might depend on it.
Not just a map. Star chart, compass, sun calculator, bearing tools, reference cards. Six tools that replace six apps.
Dark, minimal, precise. Designed for focus under stress. Looks like a tool, not a toy.
No analytics. No tracking. No data collection. Nothing leaves your device. Your survival data is yours alone.
When advice matters most, accuracy is non-negotiable.
Every AI response cites specific documents with page and section references so you can verify the advice yourself.
Medical, plant identification, and first aid topics automatically display amber safety banners. The AI doesn't pretend to be a doctor.
The AI says when it doesn't have good information rather than guessing. Silence is safer than confident misinformation.
Nothing leaves your device. The AI server runs on 127.0.0.1. No telemetry, no analytics, no phone-home. Ever.
The AI leads with what to do — numbered steps, multiple approaches from most practical to least. Made for urgency.
Plain language. No jargon. No filler. Like a field manual written by someone who's been there.
The smartest thing in your pack.
