Finally.
An AI that knows you.
GreatOak is a personal AI companion with long-term memory. It runs on a private server that belongs to you, is always available on Telegram, and gets better the longer you use it — $49/month, cancel anytime.
Not the internet. Not everyone. You. Your world, your people, your work — remembered, every day, for years.
You've introduced yourself
to AI a hundred times.
Watch what happens to everything you say.
So we built the one that stays.
It remembers.
That changes everything.
Not "remembers" like a settings page. Remembers like a friend does — the stuff that matters, when it matters.
Talk is cheap.
It does things.
While you were living your life this morning, your AI was living it too.
It cares enough
to disagree.
Every other AI is built to please you. Yours is built to help you — and sometimes help sounds like "no."
Your life stays
your life.
An AI that knows this much about you has to answer to you — and only you.
Private conversations.
What you tell your AI stays between you and your AI. Encrypted, private, yours.
You’re the customer, not the product.
We sell subscriptions, not you. No ads, no data brokers, no fine-print surprises. Ever.
See everything it knows.
Open the memory book anytime. See what’s remembered, edit it, or erase it — and erased means erased.
Leave anytime. Take everything.
Export your entire history whenever you want. Your memories are yours — that’s not a feature, it’s the deal.
The only AI that gets better
because of you.
Everyone's AI gets smarter with new models. Only yours gets wiser with every year you spend together.
Ready in a minute.
Yours for life.
Name your AI
Pick a name and a personality that feels right. This is the start of something long.
Say hello
Tell it about your world — as much or as little as you like. It starts remembering from the first message.
Just talk
Message it on Telegram like you'd message anyone. No app to learn. No manual. It's that simple.
