Beautiful, AI-native markdown IDE and LLM wiki

What it solves

OpenKnowledge is a private, local, and free markdown editor designed for creating knowledge bases, LLM wikis, and engineering specs. It bridges the gap between a rich, Notion-like editing experience and a developer-focused workflow, allowing users to manage documents in local folders (like Obsidian vaults) while integrating directly with AI agents.

How it works

The tool operates as a WYSIWYG editor that opens local folders containing markdown or mdx files. It integrates with AI harnesses such as Claude, Codex, and OpenCode via MCP (Model Context Protocol) and CLI, enabling side-by-side AI editing. It uses git and GitHub for no-code team sharing and auto-syncing of documents.

Who it’s for

It is aimed at developers, engineers, and individuals building "second brains" or structured knowledge bases who want a rich visual editor combined with agentic AI capabilities.

Highlights

  • WYSIWYG Markdown Editing: Editing feels like Google Docs or Notion but saves to local markdown files.
  • AI-Agent Integration: Side-by-side editing with Claude, Codex, and others via MCP/CLI.
  • Knowledge Graph Support: Includes a graph wiki link viewer and agentic search for LLM wikis.
  • Cross-Platform: Available as a desktop app for macOS, Windows, and Linux, or as a local web app via CLI.
  • Git-Powered Sync: Uses git/GitHub under the hood for seamless team sharing and auto-sync.

    vercel-labs/lat.md

    lat.md is an npm‑distributed CLI that creates a markdown‑based knowledge graph for a codebase. It lets you write linked documentation in `lat.md/`, annotate source files with `@lat` comments, and validates the graph. Agents and developers can search it semantically (offline MiniLM or remote OpenAI/Vercel embeddings) and use commands like `lat check`, `lat locate`, and `lat expand` to keep design decisions, constraints, and test specs in sync with the code.
