What you can make with note

The holograms over the city. Each one only uses what the kit can do today; the ones marked Template open a published Kition template.

  • Example

    Research wiki

    Notes linked with backlinks and tags grow into a map of what you have read, searchable across the whole workspace.

    Uses: Connected notes · Full-text search

  • Example

    Design doc with diagrams

    Mermaid flowcharts and KaTeX formulas render right inside the Markdown, so the doc and its diagrams stay in one file.

    Uses: Diagrams and math

  • Example

    Meeting notes the agent tidies

    The agent turns raw notes into decisions and action items; every addition and deletion is shown for you to accept or reject.

These are real commands from this kit’s engine. An agent sends them over the Kit Harness Protocol and gets the edited file back.

  • text.readRead the document text
  • text.insertInsert text at a position
  • text.replaceReplace a span of text
  • document.replaceRewrite the whole document
  • comment.addStart a comment thread
  • comment.resolveResolve a thread

Use with your AI

Kition ships an MCP server for its kits. Run it over stdio against a folder, without the app open, and your agent gets tools like note_inspect, note_run and note_check for every kit.

# Claude Code
claude mcp add kition -- kition-kits-mcp --workspace /path/to/your/folder

# Any MCP client (mcpServers config)
{
  "mcpServers": {
    "kition": {
      "command": "kition-kits-mcp",
      "args": ["--workspace", "/path/to/your/folder"]
    }
  }
}

The kition-kits-mcp binary comes with Kition. Without a licence key it runs in development and evaluation mode.
