Emergency preparedness built around you.
A companion you set up calmly — not a panic button.
An offline-ready household preparedness and reference companion — for planning, your records, and learning.
An emergency device, a 911 substitute, or a replacement for proper training and qualified care.
Plan in advance, keep your household organized, and learn the concepts that matter.
The moments you need a plan most are the moments without a signal. SurvivalKnife is ready anyway.
Four facets of a household that's ready.
Each one works on its own. Together they turn a vague intention into a working system — calmly, in advance.
A plan for your household
Plans built around who actually lives there — medical and mobility needs, pets, your dwelling, your vehicles — with checklists everyone can follow.

Calm, legible screens you set up in advance — and that keep working when the network doesn't.
Ready when the signal isn't.
SurvivalKnife works online when there's signal — sync, updates, AI planning. When there isn't, your plans, your profile, your Field Guide, and your downloaded maps are all still right there.
Preparedness, organized for the people actually under your roof.
Built for household privacy.
The most useful preparedness data is the most personal. We treat it that way.
On-device by default
Your plans, calculators, and household data are designed to live on your phone — not in our cloud.
Vault separated from search
IDs, prescriptions, and sensitive items live in the Personal Vault — never synced, never sent to AI, under any setting.
Minimized, never sold
When AI builds a plan, family profiles are sent with first names only — never their phone numbers or emails. Saved emergency contacts and addresses are sent in full so the plan can use them. You choose what your household shares and can turn any category off. Nothing is sold.
