For example
What you could ask it
It answers from whatever files you put on it, like these:
- "What time do the kids get out of school on Wednesday?"
- "What's the pediatrician's after-hours number?"
- "When is the car insurance due, and how much is it?"
Why private matters
Your family's records stay in your home
Three in four Americans (77%) are worried about the privacy of medical information they give to AI tools. KFF health poll, March 2026
The federal health privacy law, HIPAA, protects your records at the doctor's office. It does not cover a chatbot company you hand them to. HHS
When the AI runs on a computer in your home, no AI company ever receives your family's information.
The difference
Where do your files go?
With ChatGPT, whatever your family type travels over the internet to another company's computers. With a private AI, your files, questions and answers stay on one computer in your home.

Files and questions leave your home.
Private AI Set up in your home
Files, questions and answers stay on one computer in your home.
How it works
Four steps, all inside your home
One computer in your home
I set up the AI on one desktop computer that stays in your home. You copy your files onto it, so I never need to see them.
You ask
Each person signs in to a chat window on a laptop or computer at home and types a question, the same way they would use ChatGPT. Only people you add can sign in.
It answers from your files
The AI on the home computer finds the answer in your files, writes it in plain English, and names the files it used. It does not use the internet.
You can check
Open the named file to confirm the answer before you act on it.
The proof
I tested it before offering it
I made up a family of four with five everyday files: the kids' school schedule, medical notes, insurance card details, household bills and emergency contacts. Then I asked 8 questions a parent would ask, and ran the set 3 times.
These were short, clean files. Your real files, such as long PDFs and scans, are what the setup and tuning are for.
What it costs
We work out the price on a call
Every family's files are different, so I give you a price on a 20-minute call, before you pay anything. On the call we go over which files you want on it and whether a computer you have is fast enough.
Questions
Common questions
How much does it cost for a family?
We work out the price on a short call, before you pay anything. You also need one computer for it, unless one you have is fast enough.
What files can it read?
Files you copy onto it, like school schedules, medical notes, insurance details and bills. My test used short, clean files. Long PDFs and scans are what the setup and tuning are for.
Do you see our files?
No. Your family copies the files onto the computer, so I never need to see them, and no AI company ever receives them.
Isn't this just ChatGPT?
It works the same way: you type a question and get an answer. Two things differ. It runs on a computer you own, so nothing you type leaves. And it answers from your own files and names the file, instead of from the internet. When the answer is not in your files, it says so.
What computer do I need?
One store-bought computer, about $1,150 to $2,200: a desktop with a strong graphics card, or a Mac mini with plenty of memory. I tell you exactly which one to buy, or check whether one you have is fast enough.
