When the internet's gone, you still have someone to ask.
Plug it into any Windows laptop and talk it through — purifying water, treating a burn, keeping food safe in an outage, or just wording a hard email. The AI runs from the drive. Nothing you type leaves the room.
The app, on first open. Ask something, drop a document, or open the Field Manual.
I.What it is
ChatGPT needs the cloud. This needs a USB port.
Cloud AI stops working the moment your internet, your account, or the company behind it goes away. OfflineMind puts the whole thing — the app, the AI, and a survival field manual — on one drive in your pocket. Nothing to install. No account. No subscription. Nothing you type ever leaves the laptop.
It's for the day the power's out and you need to make water safe. And it's for every ordinary day before that, as a private assistant whose answers don't travel.
II.How it works
Plug in. Double-click. Ask.
01 Plug it in
Any Windows 10 or 11 laptop with 8 GB of memory. No setup, no admin rights, no internet.
02 Double-click "Start OfflineMind"
The app and the AI run straight off the drive. First start takes about a minute while the AI wakes up.
03 Ask
Type like you'd text a knowledgeable friend. Answers come from the drive — not from a server somewhere.
III.What you'd ask it
In an emergency.
The power's out, the water's off, someone's hurt and the phones are down. Describe what's happening. The AI answers calmly, step by step, drawing on the Field Manual — how to disinfect water, dress a wound, keep food safe, stay warm, signal for help.
Off the grid.
A cabin, a boat, the back country, a trip abroad with no signal. Plan repairs, troubleshoot a generator, stretch your supplies, learn a knot. The expert comes with you because it lives on the drive.
Every day, privately.
Word a difficult email. Talk through a decision. Explain something you almost understand. Plan a week of dinners. The same things you'd ask a cloud AI — except none of it leaves the room.
Show it a photo.
A rash, a mystery part, a warning label, a sign in another language, an error message. Drop the photo in and ask. It's read on your laptop — never uploaded anywhere.
About your own documents.
Drop in a .txt, .md, .csv, or .html file — an insurance policy, a manual, your notes — and ask questions. The AI cites the exact passages it draws from. Point it at a whole folder and every chat can use it.
Drop a document. Ask. Get cited answers from your own files.
IV.A page from the Field Manual
133 reference cards. Readable like a book, even with the AI off.
Each card is one situation: what to do right now, what people get wrong, and what to do if you have ten minutes. Tap a question on any card to ask the AI about your exact situation.
Water
Make water safe to drink
Boil for one minute. Three above 6,500 ft. If you can't boil, use plain bleach.
Do this now
Filter cloudy water through cloth or paper.
Rolling boil. One minute. Three at altitude.
Let it cool. Store in covered containers.
Common mistakes
Boiling chemicals or radioactive water. Boiling kills germs, not poisons.
Using scented bleach. Plain only.
Skipping the pre-filter. Disinfection fails on cloudy water.
If you have 10 minutes
No way to boil? Plain bleach: 8 drops per gallon. Wait 30 minutes.
Double the bleach if water is cloudy, colored, or very cold.
Filter first, then disinfect. Most camping filters miss viruses.
Thirteen categories ship on every drive: Water, Fire, First Aid, Shelter, Signal, Food, Security, Power, Communication, Sanitation, Navigation, Medicine, Hazards. Distilled from CDC, EPA, USDA, FEMA, and Red Cross guidance.

Four AI models in the chat dropdown: Heavy for the best answers, Standard for fast everyday use, Vision for photos, and Unfiltered for direct answers when the others get overly cautious. Pick per conversation.
VI.Reserve a drive
Two ways to get it.
A loaded USB drive — $45.99, shipped to you in a Faraday bag. Plug in and go; it has never touched the internet and never will. Or the download — $29.99 — same app, same Field Manual; it fetches its AI models once on first run, then never touches the internet again. One email when each is ready. No marketing follow-ups.
On the list.
One email when drives are ready. That's it.
VII.Common questions
Does it really work without the internet?
Yes. The AI runs on your laptop, from the drive. Pull the Wi-Fi, it works exactly the same. No message ever leaves your computer.
Drive or download — what's the difference?
The drive ($45.99) arrives loaded, in a Faraday bag; it has never needed and will never need the internet. The download ($29.99) is the same product, smaller up front — on first run it downloads the AI models once (you pick which), then it's fully offline forever. Unzip it onto your own USB stick and it's the same thing.
What computer do I need?
Windows 10 or 11 and at least 8 GB of memory. 16 GB makes the bigger model comfortable. Nothing gets installed on the computer.
How smart is it, compared to ChatGPT?
About as smart as the cloud was eighteen months ago. Smart enough for almost anything most people ask. The trade-off is privacy — and that this brain doesn't get worse, more expensive, or shut off.
Subscription? Account?
Neither. One-time purchase. Works forever.
What's the "Unfiltered" model?
A variant with the refusal training removed, for when the standard models lecture you about a benign question. Same drive, your choice, your judgment.
Can it look at photos?
Yes. Drop a photo into the chat and the Vision model on the drive reads it — screenshots, handwritten notes, mystery objects, foreign menus, error messages. Fully offline, never uploaded.
Is the Field Manual a replacement for training?
No. It's distilled from CDC, Red Cross, and FEMA guidance. Call 911 in an emergency. Take a first-aid class. The cards remind; they don't replace muscle memory.
Mac version?
Windows ships first. Mac follows once Windows is rock solid.
