Nucleus is a private, local workspace where your files, notes, and conversations become context your AI can actually use — without anything ever leaving your machine.
Every time you open a new AI chat, you start from zero. You re-paste the same context. You re-explain who you are and what you're working on. Your notes live in one app, your files in another, your conversations in a third. Nothing talks to each other. Nothing remembers. And the smarter AI gets, the more this gap costs you.
And who cannot afford their data to live in someone else's cloud.
Install Nucleus on your Mac. Pick a template that matches your work — a law practice, a clinic, a personal knowledge system. Dictate into it with Echo, drop in documents, write notes. Ask it anything, and your AI answers with the full context of your own work.
"Nucleus is the first layer of a sovereign context system for the AI age. As AI agents, humanoid robots, and intelligent systems enter every part of life, the question of who holds the truth about you — and who gets to read it — becomes the most important question in computing. Nucleus is our answer."
