What is Understand Anything?
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 solves this. It combines LLM intelligence with static analysis to produce a living, explorable map of your project — with plain-English explanations for every file, function, class, and dependency.Analyze your codebase
Run
/understand to launch a multi-agent pipeline that scans every file, extracts structure, and builds a knowledge graph saved to .understand-anything/knowledge-graph.json.Explore the dashboard
Run
/understand-dashboard to open an interactive web UI — your codebase visualized as a color-coded graph, searchable and clickable.Who is it for?
Junior Developers
Get guided tours that walk you through the architecture step by step, with every function and class explained in plain English. Stop drowning in unfamiliar code.
Product Managers
Finally understand how the system actually works without reading code. Ask “how does authentication work?” and get clear answers grounded in the real codebase.
AI-Assisted Developers
Give your AI tools deep context. Use
/understand-diff before code review, /understand-explain to dive into any module, and /understand-chat to reason about architecture.Key features
Interactive Knowledge Graph
Files, functions, classes, and 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.
Multi-Platform
Works with Claude Code, Codex, OpenCode, Cursor, OpenClaw, and Antigravity.
