What is Nogic?

Nogic is an editor extension for VS Code, VSCodium, and other Code OSS-compatible IDEs, built around a single goal: help you understand code faster. Press Cmd+K anywhere on the canvas and ask a question (“how does authentication work here?”, “walk me through the request lifecycle”, “what happens when the token expires?”). An AI client (Claude Code or Codex) answers by drawing the explanation. Architecture, sequence, dataflow, state machine, and ER diagrams unfold step by step, with a narrative cursor that walks you through each piece. The AI client reads your real code via its own tools, so this works in any language. Nogic also turns your workspace into an interactive map of files, classes, functions, and the connections between them. The map is useful on its own for exploring, but more importantly, it’s the substrate for Diff Analyze: changes get smart-ordered by dependency, classified, and scored by blast radius so you read the right code in the right order, not an AI summary instead of the code.

​

Why Nogic?

Most AI tooling tries to summarize code for you. Summaries replace comprehension; you skim, you trust, you merge, and the codebase grows more opaque to you over time. Nogic takes the opposite approach: show the code with superpowers, don’t summarize it.

• AI explains code visually instead of textually: diagrams you can navigate, not paragraphs you skim
• Diff analyze surfaces which code deserves attention (risk, blast radius, classification) without writing the review for you
• The visualization makes structure and connections legible so you don’t have to keep them in your head

You’re still reading the code. Nogic just makes sure you’re reading the right code, in the right order, with the right context.

What you can do

​

Privacy

Your code stays on your machine. Parsing, indexing, visualization, and the MCP server all run locally inside your editor. No code, files, or personal data is sent to external servers. Prompts you type into Cmd+K go to whichever AI CLI you’ve configured (Claude Code or Codex). Nogic itself doesn’t proxy or log them. See nogic.dev/telemetry for the (anonymous) metrics the extension does collect.

​

Language support

The AI canvas works on any codebase because the AI client reads files with its own native Read / Glob / Grep. It doesn’t need Nogic’s symbol index. Press Cmd+K in Rust or Go and you’ll still get diagrams. The graph-backed features (visualizer view, diff analyze scoring, the high-verbosity render_code_tour) need parsed symbols, which today means JS / TS / Python. More languages are on the way.
