What is Understand-Anything?

What it is

Understand Anything is an open-source TypeScript project, released under the MIT license and developed by Egonex from an original creation by Lum1104. It ships as a plugin for Claude Code and also works with Codex, Cursor, Copilot, Gemini CLI and other agent platforms. The project analyzes a codebase through a multi-agent pipeline that extracts every file, function, class and dependency, then builds a knowledge graph which it presents in an interactive dashboard. A hosted live demo is available on the project homepage for anyone who wants to pan, zoom, search and explore without running the analysis locally.

The concrete problem it addresses is orientation. A developer joining a team that owns a large codebase has no obvious starting point, and reading code file by file gives no picture of how the parts fit together. Understand Anything replaces that blind reading with a navigable graph of the system. The stated goal is not a graph that impresses with complexity, but one that teaches how every piece connects. It extends the same treatment to non-code material: the /understand-knowledge command points at a Karpathy-pattern LLM wiki and produces a force-directed knowledge graph with community clustering, where a deterministic parser extracts wikilinks and categories from index.md before LLM agents discover implicit relationships, extract entities and surface claims.

Key capabilities

  • Structural graph exploration over every file, function and class as a clickable, searchable node with plain-English summaries, relationships and guided tours.
  • Domain view that maps code to business processes as domains, flows and steps laid out in a horizontal graph.
  • Knowledge base analysis of Karpathy-pattern wikis via /understand-knowledge, producing force-directed graphs with community clustering.
  • Guided tours generated automatically from architecture and ordered by dependency, so the codebase can be learned in the correct sequence.
  • Fuzzy and semantic search that finds nodes by name or by meaning, such as retrieving relevant results across the graph for a question about authentication handling.
  • Diff impact analysis showing which parts of the system a change affects before it is committed.
  • Persona-adaptive dashboard detail levels for junior developers, product managers and power users, plus automatic layer grouping into API, Service, Data, UI and Utility with a color-coded legend, and in-context explanations of 12 programming patterns.

Who uses it and how

  • Developers onboarding onto large unfamiliar codebases, who run /understand and explore the resulting graph instead of reading files blind.
  • Teams reviewing changes, who use diff impact analysis to see ripple effects across the system before committing.
  • Engineers working with knowledge bases, who point /understand-knowledge at an LLM wiki and navigate the extracted entities and claims.
  • Privacy-sensitive or enterprise setups, where the platform is pointed at a local model provider such as Ollama.
  • Non

Understand Anything

Turn any codebase, knowledge base, or docs into an interactive knowledge graph you can explore, search, and ask questions about.
Works with Claude Code, Codex, Cursor, Copilot, Gemini CLI, and more.

Understand Anything. Understand Anyone.
AI should help people, not replace them.

An open-source project from Egonex
Originally created by Lum1104.

You just joined a new team. The codebase is 200,000 lines of code. Where do you even start?

Understand Anything is a Claude Code Plugin that analyzes your project with a multi-agent pipeline, builds a knowledge graph of every file, function, class, and dependency, then gives you an interactive dashboard to explore it all visually. Stop reading code blind. Start seeing the big picture.

The goal isn't a graph that wows you with how complex your codebase is — it's a graph that quietly teaches you how every piece fits together.

✨ Features

[!NOTE] Want to skip the reading? Try the live demo in our homepage — a fully interactive dashboard you can pan, zoom, search, and explore right in your browser.

Explore the structural graph

Navigate your codebase as an interactive knowledge graph — every file, function, and class is a node you can click, search, and explore. Select any node to see plain-English summaries, relationships, and guided tours.

Understand business logic

Switch to the domain view and see how your code maps to real business processes — domains, flows, and steps laid out as a horizontal graph.

Analyze knowledge bases

Point /understand-knowledge at a Karpathy-pattern LLM wiki and get a force-directed knowledge graph with community clustering. The deterministic parser extracts wikilinks and categories from index.md, then LLM agents discover implicit relationships, extract entities, and surface claims — turning your wiki into a navigable graph of interconnected ideas.

🧭 Guided Tours

Auto-generated walkthroughs of the architecture, ordered by dependency. Learn the codebase in the right order.

🔍 Fuzzy & Semantic Search

Find anything by name or by meaning. Search "which parts handle auth?" and get relevant results across the graph.

📊 Diff Impact Analysis

See which parts of the system your changes affect before you commit. Understand ripple effects across the codebase.

🎭 Persona-Adaptive UI

The dashboard adjusts its detail level based on who you are — junior dev, PM, or power user.

🏗️ Layer Visualization

Automatic grouping by architectural layer — API, Service, Data, UI, Utility — with color-coded legend.

📚 Language Concepts

12 programming patterns (generics, closures, decorators, etc.) explained in context wherever they appear.

🚀 Quick Start

1. Install the plugin

/plugin marketplace add Egonex-AI/Understand-Anything
/plugin install understand-anything

Using a local model? For privacy or enterprise setups, point your platform at a local model provider such as Ollama — follow their integration guide to change the model provider.

2. Analyze your codebase

/understand

A multi-agent pipeline scans your project, extracts every file, function, class, and dependency, then builds a knowledge graph saved to .ua/knowledge-graph.json. (Projects that already have a .understand-anything/ directory keep using it — it stays the data directory when present, so nothing needs migrating.)

Heads up on token usage: The initial /understand analyzes your whole codebase and can consume a significant number of tokens on large projects. We recommend running it on a token plan / subscription, or using a local model (see above) for initialization. Subsequent runs are incremental by default — only changed files are re-analyzed — so they use far fewer tokens.

Localized output: Use --language to generate content in your preferred language:

# Generate Chinese content (知识图节点描述和 Dashboard UI)
/understand --language zh

# Supported languages: en (default), zh, zh-TW, ja, ko, ru

On the first run in a project — when you don't pass --language and no language is stored yet — /understand detects the language you're conversing in. If it isn't English, it asks you to confirm (or override) before generating; English conversations are unaffected. Your choice is saved to .ua/config.json and reused on every later run.

The --language parameter affects:

  • Node summaries and descriptions in the knowledge graph
  • Dashboard UI labels, buttons, and tooltips
  • Guided tour explanations

3. Explore the dashboard

/understand-dashboard

An interactive web dashboard opens with your codebase visualized as a graph — color-coded by architectural layer, searchable, and clickable. Select any node to see its code, relationships, and a plain-English explanation.

4. Keep learning

# Ask anything about the codebase
/understand-chat How does the payment flow work?

# Analyze impact of your current changes
/understand-diff

# Deep-dive into a specific file or function
/understand-explain src/auth/login.ts

# Generate an onboarding guide for new team members
/understand-onboard

# Extract business domain knowledge (domains, flows, steps)
/understand-domain

# Analyze a Karpathy-pattern LLM wiki knowledge base
/understand-knowledge ~/path/to/wiki

# Re-run anytime — incremental by default (only re-analyzes changed files)
/understand

# Auto-update on every commit via a post-commit hook
/understand --auto-update

# Scope to a subdirectory (for huge monorepos)
/understand src/frontend
