Introduction
You just joined a new team. The codebase is 200,000 lines of code. Where do you even start? Understand Anything is a multi-platform AI coding 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.Understand Anything is open source under the MIT license and works natively with Claude Code, with support for Codex, OpenCode, Cursor, OpenClaw, and Antigravity.
What it does
Reading code is hard. Understanding a whole codebase is harder. Documentation is always out of date, onboarding takes weeks, and every new feature feels like archaeology. Understand Anything fixes this by combining LLM intelligence with static analysis to produce a living, explorable map of your project — with plain-English explanations for everything. The/understand command orchestrates 5 specialized agents across 8 phases (Phase 0 pre-flight through Phase 7 save):
| Agent | Role |
|---|---|
project-scanner | Discover files, detect languages and frameworks |
file-analyzer | Extract functions, classes, imports; produce graph nodes and edges |
architecture-analyzer | Identify architectural layers |
tour-builder | Generate guided learning tours |
graph-reviewer | Validate graph completeness and referential integrity |
Who it’s for
Junior Developers
Stop drowning in unfamiliar code. Get guided tours that walk you through the architecture step by step, with every function and class explained in plain English.
Product Managers & Designers
Finally understand how the system actually works without reading code. Ask questions like “how does authentication work?” and get clear answers grounded in the real codebase.
AI-Assisted Developers
Give your AI tools deep context about your project. Use
/understand-diff before code review, /understand-explain to dive into any module, or /understand-chat to reason about architecture.Key features
Interactive Knowledge Graph
Files, functions, classes, and their relationships visualized with React Flow. Click any node to see its code and connections.
Plain-English Summaries
Every node described by an LLM so anyone — technical or not — can understand what it does and why it exists.
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.
Layer Visualization
Automatic grouping by architectural layer — API, Service, Data, UI, Utility — with color-coded legend.
Output
After running/understand, the plugin writes two files to your project:
.understand-anything/knowledge-graph.json— The full graph with nodes, edges, layers, and tour steps.understand-anything/meta.json— Metadata including the git commit hash for incremental update tracking
