The plan

Your second brain
for AI.

A local memory that is yours, that every AI agent you use can read and add to, and that you see and organise in a native app. This is how we are building it, in public.

Follow the roadmapRead the handbook

What it is

  • One memory for every agent

    Claude Code, Codex, Gemini and Claude Desktop read and write the same memory through MCP.

  • Notes and conversations

    Your notes and everything that comes out of each conversation, connected as nodes and links.

  • Spaces with permissions

    Work and personal apart. Each agent only sees what you let it.

  • Local and open

    Your files, on your Mac, in an open format. Every node is Markdown. No AI inside the app: the agent is the AI.

How it works

Knode Service

In the menu bar. A Rust core, the only process that opens your spaces, and the one that enforces permissions. The Mac app talks to it too.

  • A package, like a Music library: one file in the Finder, a folder inside.
  • Search three ways, locally: by words, by meaning, and both at once for agents.
  • Everyone at once: you, Claude and Codex write together, and nothing is lost.
  • Every node is Markdown, and a space can also live as a folder of .md files for Obsidian, git and anything else.

Capture

Every conversation is kept on its own. Turn it off per project, and choose which folders feed each space.
