Understand-Anything: Turn Any Codebase Into an Interactive Map That Teaches You How It Works

An open-source plugin sends five AI agents through any codebase and turns it into an interactive map of every file, function, and dependency, so you can see how the whole thing fits together instead of reading it line by line.

Understand-Anything is an open-source plugin that turns any codebase into an interactive map you can explore and search. Point it at a project and a pipeline of five specialized AI agents analyzes it, then builds a graph where each file, function, and class is a node and the links between them show what calls or depends on what. It splits the work in two: Tree-sitter, a parser that reads code structure consistently, pulls the hard facts like imports and call sites, while a language model adds what a parser cannot: plain-English summaries, each file’s architectural layer, and how the code maps to business processes. The result is saved as JSON and opens as a dashboard.

It targets the moment you join a team and face 200,000 lines of unfamiliar code. Instead of reading it blind, you get a map color-coded by layer (API, service, data, UI), guided tours through the architecture in dependency order, and search that answers questions like “which parts handle auth?” by meaning, not keyword. Because the graph is plain JSON, a team can commit it once so everyone else skips the analysis, like committing docs. Another view shows what your current changes will affect before you commit them.

This flips the usual goal of code-graph tools. CodeGraph builds a similar graph to cut the tokens an AI agent burns reading files. Understand-Anything points the same idea at the person: its tagline says most tools show you a hairball, this one tries to teach you the codebase.
