Why we built Sage.
Most AI meets you brilliant and blank. We wanted one that actually remembers you — and treats that memory like it’s yours, because it is.
The problem
The smartest AI in the world still starts every conversation from zero. You re-explain your projects, your team, your history — over and over — and the moment you close the tab, it forgets. That isn’t just annoying. It wastes the most valuable thing a personal assistant could ever have: the relationship. Something that forgets you can answer questions, but it can’t really help you.
What we believe
We believe your memory should be yours. The picture an AI builds of your work, your people, and your goals is some of the most personal data there is, and it should be private, portable, and under your control — never sold, never used to train someone else’s model. You can export all of it whenever you want. You can delete any piece of it, or all of it, anytime. Privacy isn’t a setting we bolted on. It’s the foundation we started from.
Who’s behind it
Sage is built by Perpetual Core, a small team that makes focused tools for people with a lot to hold. It’s part of a little family of products that share the same belief: software should adapt to you, not the other way around. We’re not trying to build everything — just a few things that earn a permanent place in how you work.
Our mission
We want to give you an AI that grows more useful every day because it remembers — one that briefs your morning, reads what you hand it, drafts in your voice, and keeps the threads straight, all from a memory you own and can walk away with. That’s the whole idea. No hype, no lock-in. Just a tool that finally knows you, and stays on your side.
