The problem with big AI

Every Question
You Ask Gets Logged.

When you type a question into ChatGPT, Google Gemini, or any cloud AI, that question travels across the internet to a server you don't own — and it stays there.

Your late-night health worries. Your financial concerns. Your most personal questions. All of it gets stored, analyzed, and in many cases, used to train their next model.

You're not using a tool. You're feeding a machine.

NoBigBrother is different. Once it's on your machine, your conversations go exactly nowhere. Not to us. Not to anyone.

Ask It Anything

Write, research, brainstorm, get advice. Whatever you'd normally ask a cloud AI — now privately, on your own terms.

One honest thing to know

It Knows A Lot.
Not Everything.

NoBigBrother's AI was trained on information available through approximately late 2023. Think of it as a brilliant, well-read friend who's been completely off the grid for a couple of years.

It knows an enormous amount — history, science, medicine, law, writing, technology, cooking, finance, and much more. But it won't know about things that happened after its training ended: recent news, new album releases, current prices, or anything else from 2024 onward.

There's a second thing worth knowing: like all AI of this kind, it can occasionally get a specific fact wrong — a date, a name, a stat — even for things well before 2023. It might say a band's last album came out earlier than it actually did, or misremember a sports record. This isn't unique to NoBigBrother; it's true of ChatGPT and every other AI on the market. For anything where getting a precise fact exactly right truly matters, double-check it the way you'd double-check anything important.

The simple rule: use NoBigBrother for knowledge, thinking, and writing — where it shines. For breaking news or a fact you're staking something on, verify it. Keep Google around for current events. They complement each other well — and only one of them is watching.

Questions

No. Once you have the file on your computer, it runs completely offline. No Wi-Fi, no data connection, no cloud. The only time internet is involved is the initial download — and even that you can skip entirely with the USB option.
It's genuinely capable — it writes, explains, brainstorms, summarizes, answers questions, and holds a real conversation. It's not identical to the largest cloud models, but it's remarkably good for everyday use. And for a growing number of people, the privacy trade-off makes it the better choice, full stop.
Windows 10 or later, or macOS 12 or later. You'll want at least 8GB of RAM (16GB is better). Most computers purchased in the last four or five years will work fine. If you're unsure, email us before you buy — we'll tell you straight.
No — and we mean that technically, not just as a policy. The AI runs on your hardware, stores everything locally on your machine, and makes zero outbound connections. Once it's on your computer, we couldn't see your conversations even if we wanted to. We don't want to.
Every purchase includes email support from a real person. USB Drive customers get priority response. We also include a step-by-step video walkthrough that covers everything from the moment you download to your first conversation.
If it doesn't work for you within 30 days of purchase, email us and we'll refund you completely. No forms, no hoops, no runaround. We want you to feel good about the purchase.
