Step 1: Install the extension
Install Nogic from the VS Code Marketplace:- Open VS Code
- Open the Extensions sidebar (
Cmd+Shift+X/Ctrl+Shift+X) - Search for Nogic (publisher:
Nogic) - Click Install
1.88.0+).
Step 2: Open the visualizer
Open any project folder, then either:- Open the Command Palette (
Cmd+Shift+P/Ctrl+Shift+P) and run Nogic: Open Visualizer, or - Click the Nogic icon in the editor title bar
~/.nogic/workspaces/. Files in other languages appear in the tree without parsed symbols; the AI canvas (Step 5 below) still works on them.
Nogic also opens the visualizer automatically when you open a workspace. Disable that in Settings → Extensions → Nogic →
nogic.openOnStartup if you prefer manual control.Step 3: Explore the graph
You’re now looking at your codebase as a connected map.- Pan / zoom with trackpad or scroll wheel
- Search with
Cmd+F(orCtrl+F) to jump to a file or symbol - Right-click any node and choose Inspect to focus it with its connections
- Right-click files or folders in the Explorer and choose Add to Nogic Board to build a focused view
Step 4: Connect an AI client
Nogic ships a local MCP server that lets AI clients draw answers directly on the canvas viaCmd+K.
When you first open the visualizer, the MCP Setup overlay appears with:
- Whether Claude Code and Codex are installed and on your
PATH - The local MCP server URL (e.g.
http://127.0.0.1:54123/mcp) - Toggles to enable each CLI
Claude Code
Set up Claude Code (
Cmd+K and external use)Codex
Set up Codex (auto-managed config)
Step 5: Ask a question on the canvas
With the visualizer focused, pressCmd+K (or Ctrl+K). The on-canvas Director cursor opens. Type something like:
Walk me through how authentication works in this app.Nogic streams your prompt to the active CLI, which calls the local MCP server. Within seconds the canvas reflows into a diagram with a step-by-step narrative: sequence, dataflow, state machine, ER, or a curated tour of real code, depending on the question. See Agent Canvas for what the AI can render and how to drive it.
