What You Download

One install. Three things that change everything.

JeffyAI ships as a complete offline AI hub. No subscription. No cloud account. No monthly bill. Everything runs on your machine.

🤖
Bundled Free

Offline AI Chat

Talk to an AI that runs entirely on your computer. No internet required. No server logging your questions. Remembers you between sessions. Gets smarter about your life — without telling anyone else about it.

Straight talk: because it's truly offline, it can't browse the web or look up today's news — and it will tell you so instead of making something up. That's not a bug. That's the proof nothing leaves your machine.

The Test

You wouldn't undress in public.
Why does your AI?

Open your phone right now. Look at your last 10 messages to ChatGPT, Claude, Gemini, or Apple Intelligence.

Would you read those messages aloud at your job interview? Would you read them at your kid's parent-teacher conference? Would you forward them to your ex-spouse's lawyer in your custody case? Would you let your employer screenshot them and add them to your HR file?

If any answer is no — Big Tech AI already has more leverage over your life than you want it to.

People say "I have nothing to hide." Then they close the bathroom door. They don't let their boss read their text messages. They whisper at the bank. Privacy isn't about hiding. It's about choice over who sees what.

The conversations that bite hardest.

Your employer
You ask: "How do I negotiate a raise without them knowing I'm looking elsewhere?"
Your company's IT can monitor AI tool usage on corporate networks — it's legal and common. Samsung banned ChatGPT companywide after engineers accidentally pasted proprietary source code into it. Reuters, May 2023 ↗ Local AI: your career strategy stays on your machine.
Data breach
You ask: "Help me plan my medical treatment for [condition]"
In March 2023 a ChatGPT bug exposed other users' conversation titles and payment data. OpenAI confirmed it publicly. Cloud services get breached — it happens. OpenAI, March 2023 ↗ Local AI: nothing on a server means nothing to breach.
Business strategy
You ask: "Here's our Q3 financial plan — help me find the weak spots."
OpenAI's default data retention is 30 days. Enterprise plans vary. Attorneys have already begun requesting AI conversation logs via discovery in commercial litigation. Your confidential business data becomes their exhibit. Local AI: your strategy never touches their servers.
Divorce & custody
You ask: "Help me write a response to my ex's lawyer."
Digital messages — including AI chat logs — are discoverable in family court. Opposing counsel can subpoena them from cloud providers, and providers must comply. Local AI: the conversation doesn't exist on any server to subpoena.
Mental health
You ask: "I've been struggling badly — can you just help me think through this?"
Insurance companies are increasingly using digital behavioral data in underwriting. Mental health disclosures in cloud AI logs are stored indefinitely under most terms of service. Local AI: what you say in your worst moments stays in your worst moments — and nowhere else.
Money trouble
You ask: "I'm underwater on debt — walk me through my options."
Lenders and landlords are beginning to use AI-aggregated behavioral data in credit and rental decisions. A conversation about bankruptcy today could surface in an underwriting model tomorrow. Local AI: your finances are between you and your accountant.
Whistleblowing
You ask: "Help me document what I've seen — I'm going to report this."
Cloud AI providers comply with valid legal process, including subpoenas from the very organizations you're reporting. The EFF has documented how cloud data can be compelled by third parties. EFF: Surveillance ↗ Local AI: your documentation doesn't exist on any server they can reach.
There's a difference between "we won't read your data" and "we can't read your data."

Big Tech AI says the first. JeffyAI does the second. Their privacy is a policy that can change tomorrow. Ours is an architectural fact that can't.

The Story

Built by one person.
For everyone.

My name is Jeff Johnson. I'm in the Pacific Northwest. I'm not a Silicon Valley startup. I don't have venture capital. I designed JeffyAI because I was tired of Big Tech AI listening to everything I say, selling my data, and telling me what I'm allowed to do with my own computer.

I wanted an AI that knew me — really knew me — without sending my life story to a server farm in California. I wanted something that ran on my machine, answered to me, and got smarter over time without ever phoning home.

So I designed it. And built it with my Claude AI partners. Months of late nights, hundreds of iterations, thousands of lines of code that the AIs and I wrote together. JeffyAI is the personal AI operating system I always wanted — and I think you want it too.

Take that, Silicon Valley.

🔐 Straight answers

How can it be offline and secure?

Offline means there is nothing to hack into.

Cloud AI is secure the way a bank vault is secure — your stuff sits in their building, guarded by their rules, visible to their staff and anyone with a warrant. JeffyAI doesn't harden the vault. It removes the building. Your words are processed on your own machine and never travel anywhere. You can run it in airplane mode forever — there is no server, no account, no "up there."

Encrypted means even your own device keeps the secret.

Your journal and personal data are sealed with AES-256 — the same cipher governments use for classified material — locked by a passphrase that only exists in your head. Lose the phone and whoever finds it holds scrambled noise. We never see your key. We can't see your key. That's the design, not a promise.

The honest fine print.

The protection covers your data while it stays inside JeffyAI's encrypted storage. If you export, copy, screenshot, back up, or move your data out of the encrypted vault, it leaves our protection and its safety is your responsibility — we are not responsible for data once you move it out. And because there is no server and no account, there is no password reset: if you lose your passphrase, nobody on Earth — including us — can recover your data. That's not a limitation. That's what private actually means.
