IWE

A markdown knowledge graph for you and your AI agent.

IWE turns a directory of markdown files into a knowledge graph — a connected structure you browse from your editor and your AI queries from the command line. Same files, same links, two interfaces. No cloud, no database, no lock-in. Version everything with git.

Write in Markdown, structure with links, give AI agents the tools to navigate your knowledge. IWE itself has no built-in AI — it works alongside Claude, Codex, Gemini, and any tool that speaks the Model Context Protocol.

What You Get

• Plain markdown, full ownership. Your notes are .md files in a local directory. Read them, edit them, git push them. Nothing proprietary.
• A graph, not a folder tree. Link notes together and the same note can belong to multiple topics without copying the file. (How linking works)
• IDE features for your editor. Real LSP integration with VS Code, Neovim, Zed, and Helix — search, refactor, rename, autocomplete.
• Structured access for AI agents. CLI tools and an MCP server let agents search, retrieve, and refactor the same notes you edit by hand.
• Fast. Built in Rust, processes 20,000 files in under a second.

How It Works

IWE treats your notes as a connected structure. You organize them with two types of links:

• Nesting — a link on its own line means "this topic includes that subtopic." Your notes form a tree you can browse and refactor. IWE calls these inclusion links.
• Cross-references — regular inline links connect notes across topics, creating a web of relationships.
• Multiple parents — the same note can live under several places at once. A "Meditation" note can belong to both "Health" and "Productivity" without duplicating the file.
• Context from parents — when you retrieve a note, IWE can include context from the notes above it in the hierarchy.

This structure makes retrieval powerful — whether you're browsing in your editor or an agent is querying via CLI, ask for a topic and get its full context in a single call.

Working with AI

IWE gives AI agents structured access to your notes through two interfaces: a CLI for scripting and shell-based workflows, and an MCP server for native connection with AI tools. Both expose the same operations — search, retrieve, create, refactor — so you can choose whichever fits your setup.

Integration Server (MCP)

IWE includes a server (iwec) that lets AI tools like Claude Desktop, Cursor, and Windsurf work directly with your notes using the Model Context Protocol. The server watches your files for changes, so edits you make in your editor are reflected immediately.

Command-Line Tools

The CLI lets you (and AI agents) work with your notes from the terminal or in scripts.

Example: preparing context for an AI conversation

iwe find auth

iwe retrieve --key authentication --depth 2

iwe tree --key oauth

Available commands:

Command	What it does
find	Search notes with fuzzy matching
retrieve	Get a note with its children and parent context
tree	Show the hierarchy from any starting point
squash	Flatten a subtree into one document
new	Create a note (accepts content from stdin)
extract	Pull a section into its own note
inline	Merge a linked note back into its parent
rename	Rename a note; all links update automatically
delete	Remove a note and clean up references

Editor Integration

IWE gives your editor IDE-like features for markdown notes. It works with VS Code, Neovim, Zed, Helix, and any editor that supports the Language Server Protocol (LSP).

• Search — find notes by title or content
• Navigate — go to definition, find references (backlinks)
• Preview — hover over links to see content
• Auto-complete — link suggestions as you type
• Inlay hints — show parent references and link counts
• Extract — pull sections into new notes
• Inline — embed note content back into parent
• Rename — rename files with automatic link updates
• Format — normalize documents, update link titles
• Transform — pipe text through external commands
• Templates — create notes from templates (daily notes, etc.)
• Outline conversion — switch between headers and lists

Quick Start

1. Install the CLI and LSP server:

   Using Homebrew (macOS/Linux):

   brew tap iwe-org/iwe
   brew install iwe
   

   Or using Cargo:

   cargo install iwe iwes iwec
   

2. Initialize your workspace:

   cd ~/notes
   iwe init
   

3. Pick your path:

   Set up your editor — VS Code · Neovim · Helix · Zed

   Connect your AI agent — point it at the MCP server:

   {
     "mcpServers": {
       "iwe": {
         "command": "iwec",
         "args": ["--project", "~/notes"]
       }
     }
   }
