NaiadAI

NaiadAI is a JetBrains IDE plugin that turns your codebase into live, interactive diagrams. Instead of jumping between dozens of files to understand how your code fits together, you can ask for any diagram and get a visual map in seconds. The plugin works inside IntelliJ, PyCharm, GoLand, and other JetBrains IDEs, drawing everything from class-level relationships to full system architectures.

The key feature is AI-assisted diagramming: type a request like "show me the data flow for user authentication" and NaiadAI generates a diagram from your actual code. Every node is clickable — click a class or function and you jump straight to that line of code. Diagrams stay in sync with your latest commits, so you're never looking at stale visuals. The plugin supports Java, Kotlin, Python, Go, JavaScript, and TypeScript, and comes with 12 preset diagram types split between file-scoped and architecture-scoped views.

This tool is built for developers who work with large, unfamiliar codebases. It helps new team members understand a project in days instead of weeks, lets you trace bugs across services without mentally juggling 15 open files, and gives you confidence that your changes won't break something hidden. If you spend more time reading code than writing it, NaiadAI makes that reading faster and far less painful.
