## What it is
OpenKnowledge is an AI-native WYSIWYG markdown editor and knowledge base app for humans and LLM agents, available as a desktop app (macOS, Windows, Linux) or a local web app and CLI. It integrates with Claude, Codex, and other agent harnesses via MCP and skills to co-create LLM wikis, second brains, specs, and notes stored as plain markdown files.

## Use cases
- write and edit markdown with a WYSIWYG editor
- build an LLM wiki or company knowledge base with AI agents
- manage a second brain or personal knowledge base in markdown
- co-write engineering specs with Claude or Codex
- migrate from Obsidian or Notion to a local markdown setup
- give coding agents MCP access to search and edit project docs
- share and sync team documentation via git/GitHub

## When to choose
- you want a Notion-like editing experience while keeping plain markdown files
- you want AI agents to read, search, and edit your knowledge base via MCP
- you need a local, private alternative to Notion or Obsidian with AI integration
- you maintain LLM wikis, codebase docs, or agent second brains

## When to avoid
- you need a fully hosted collaborative wiki with fine-grained permissions
- you only want a minimal plain-text markdown editor without AI features
- you require non-markdown document formats like rich Office files
