Why Nucleus

Your tools, your data, your machine.

A real framework underneath — not a pile of disconnected apps.

An infinite canvas

An unbounded, zoomable space where every node is a live widget — notes, charts, file trees, terminals. Pan, zoom, and place anything where it makes sense to you.

A real plugin ecosystem

Vibe-code a widget against one typed import … from 'nucleus', drop the folder in, and it's discovered and hot-reloaded — no rebuild, no setup. Each tool reads the same files and APIs as the rest.

Find anything by meaning

The Cartographer maps your whole vault so you never have to remember where you filed a thought. Ask in plain English and it surfaces the right note by meaning — and cites where it came from.

Local-first & offline

Everything runs on your machine through a native Rust backend, and the app works fully offline. Your data never has to leave the device.

Your files, no lock-in

Opens standard Obsidian vaults and reads Markdown, CSV, JSON, Parquet and images out of the box. Your notes stay as plain, human-readable files on disk — never trapped in an app database.

Bring your own AI

Plug in the models you choose — run them locally with Ollama, or connect your own Claude, Gemini or Codex account. No in-app middleman, no per-seat tax.
