About Understand-Anything
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.…

About obsidian-wiki
obsidian wiki is a Python package and agent skill framework for maintaining a personal knowledge base in Obsidian. It lives in the Obsidian, markdown, and AI agent ecosystem, where agents can read and run skills from a shared .skills/ directory. The project presents itself as a digital brain that remembers what a user figures out, connects new material to existing notes, and answers questions from that knowledge.
