What it is

Markdown knowledge graph — LSP for your editor, CLI + MCP memory for your AI agents
— the description by IWE

AutoGineer overview, from the brain’s own files

IWE provides a shared workspace for humans and AI agents to collaborate on project documentation, specs, and decision logs. By treating a folder of Markdown files as a structured knowledge graph, it allows agents to read, write, and organize information that persists across sessions. It functions as a memory server via the Model Context Protocol (MCP), enabling compatibility with various AI agents while remaining accessible to users through a native Mac app, CLI, or standard text editors like Neovim and VS Code.

How it works

Memory model: Not stated

AutoGineer overview, from the brain’s own files

IWE organizes notes as a collection of Markdown files within a project folder. It uses a CLI and an MCP server to expose these files to AI agents, allowing them to perform operations like searching, creating, and updating notes. The system supports features such as backlinks, link autocomplete, and graph visualization, ensuring that both the user and the AI agent interact with the same underlying document structure.

Usage

AutoGineer overview, from the brain’s own files

  • Connect an AI agent to your project notes using the MCP server.
  • Use the CLI to search, create, or reorganize notes from the terminal.
  • Write and browse notes in the native Mac app while an agent works alongside you.
  • Integrate note navigation and autocomplete into your preferred text editor.
  • Maintain a persistent record of project decisions and lessons learned that both you and your agent can access.
“Explore my IWE notes and summarize what's here.”
The agent reads the Markdown files in the designated folder and provides a summary of the project context, decisions, or documentation found.
“Save the decision we just made about the database schema.”
The agent creates or updates a Markdown note in the IWE folder containing the details of the decision for future reference.

Too many AI conversations start from zero. You explain your project, your decisions, your reasoning — then find yourself explaining it all again next session. Your own notes live somewhere else, out of the agent's reach.

Or worse, the agent “remembers” something in its own internal memory, but you can't easily see what it saved or correct what it got wrong. And that memory doesn't travel with you to the other agents you work with.

IWE gives you and your AI agents one shared place to work, right inside your project: a folder of connected Markdown documents — specs, plans, decisions, and more. Keep your own ideas there, ask your agent to save what you learn together, and return to that context as your work grows. You can read, edit, and organize those documents yourself — and they stay yours.

Choose how you work

There are four ways to work with IWE. Mix and match them to fit your day:

ToolHow you'll use it
iWe for MacWrite and browse in a native app, and connect your existing Claude/Codex agent.
Your own editorStay in Neovim, Helix, VS Code, or Zed, with note navigation, backlinks, and autocomplete.
CLISearch and manage your notes from the terminal or scripts.
Claude/CodexLet your agent read, write, and organize memory while you work through conversation.

All four work with the same Markdown documents. Draft a spec in your editor, develop it with Claude/Codex, browse it in the iWe app, or search it from the CLI. Use any combination you like; each tool also works independently.

Bring your own AI. Neither the IWE CLI nor the iWe Mac app includes an AI model. Both work on their own as tools for your notes. When you want AI help, use your existing Claude/Codex agent — in terminal or directly in the Mac app.

Why IWE

  • Shared context. Your agent can use the same notes you write for yourself. Notes link to each other, and one note can belong to several topics, so you can follow an idea wherever it connects.

  • Memory you can read. Decisions and lessons saved by your agent are ordinary notes you can browse, correct, or delete.

  • Your notes stay yours. Everything is Markdown in a folder on your machine. Back it up, sync it, or keep it in git. You don't need an IWE cloud account to keep your notes; connecting an AI agent involves that agent's own setup and account requirements.

iWe for Mac

If you'd like a dedicated space for your notes, use the native Mac app. Open a folder of notes and you get a fast, keyboard-friendly space to write and browse. You can also connect your existing Claude/Codex agent to work alongside you.

  • Works with your Claude/Codex agent. Connect the agent you already use, ask questions about your notes, and have it draft or reorganize them. Watch its edits appear in the document as it works.

  • Room to experiment. Each agent run is one undo step — try an idea, and roll it back if you don't like it.

  • Follow your ideas. Jump between related notes, search in a few keystrokes, and view Mermaid diagrams right in your documents. Your editor and other tools can keep working on the same files.

See iWe for Mac on iwe.md →

Open a notes folder and start with a note about something you're working on. Once Claude/Codex is connected, try asking it to summarize that note or help you develop an idea.

Your Own Editor

Keep writing in Neovim, Helix, VS Code, or Zed. IWE adds link autocomplete, backlinks, search, and safe renaming across your notes.

Follow the guide for your editor, open your notes folder, and try linking two notes with autocomplete. You can use IWE for your own writing without connecting an AI agent.

CLI

Prefer the terminal? Use IWE to search, create, and reorganize notes, or work it into your scripts. The CLI has no AI built in: these commands work on their own. Your existing Claude/Codex agent can use IWE's tools too.

Install with Homebrew, or choose another option from the installation guide:

brew install iwe-org/iwe/iwe

Then run these commands inside your notes folder:

iwe init
iwe find
iwe find --lexical "project decisions"

iwe find lists your notes; --lexical searches their content. Explore more in the CLI reference and workflow examples.

Claude/Codex

You can use IWE entirely through your agent. Ask Claude/Codex to save decisions, look up past work, and organize what you've learned. The agent works with your notes through IWE, and you can open those files yourself whenever you want.

IWE isn't tied to one AI. The same notes work with Claude Code, Claude Desktop, Codex, Gemini, Cursor, and any tool that supports the Model Context Protocol.

Give Claude/Codex a memory — for Claude Code, install the plugin, then run /iwe:init in any project you want remembered. For Codex, follow the agent connection steps below.

/plugin marketplace add iwe-org/skills
/plugin install iwe@iwe-org
/iwe:init

Then ask it to save a decision from your current work, and open the note it creates in your project.

Connect another agent — with Homebrew installed, install IWE:

brew install iwe-org/iwe/iwe

Run iwe init in your notes folder, then follow the agent connection guide to add the iwec MCP server with that folder as its working directory. For other installation options, see the installation guide.

Once connected, ask your agent: “Explore my IWE notes and summarize what's here.”

Or let the agent set itself up — paste this into any agent that can run commands:

Set up IWE for my notes: install it (brew install iwe-org/iwe/iwe,
npm install -g @iwe-org/iwe, or cargo install iwe iwes iwec), run `iwe init`
in my notes directory, then add the `iwec` MCP server with its working
directory set to that folder.

Feature Overview

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. This page is the catalogue: the capabilities that do not exist in a markdown language server at all, and where each one is documented.

For how IWE stacks up against marksman, markdown-oxide, Obsidian, zk, and mdbase — including where IWE is weaker — see How IWE Compares.

Graph Transformations

  • Extract and inline notes: LSP code actions that split a section into its own document or merge a referenced document back in, rewriting every affected link

  • Section-to-list and list-to-section conversions: restructure a document without retyping it

  • Sub-section extraction: break a long note into linked components, one action at a time

  • Reference inlining: turn a link into a quote, or embed the target section directly

Query Language

  • MongoDB-style YAML filters: match documents by frontmatter with $eq, $in, $gt, $exists, $all, and the rest of the operator set

  • Graph operators: $includes, $includedBy, $references, $referencedBy walk inclusion and reference edges at bounded or unbounded depth

  • Bulk mutations: iwe update and iwe delete apply the same filters across the whole workspace with $set / $unset

  • Projection, sort, and limit: shape results as JSON, YAML, or Markdown for piping into other tools

See Query Language and the formal specification.

MCP Server for AI Agents

  • 14 native tools: agents call iwe_find, iwe_retrieve, iwe_create, iwe_extract, iwe_normalize, and more over the Model Context Protocol

  • Built-in prompts: explore, review, and refactor guide agents through common workflows

  • Resources: documents, tree, stats, and config exposed as MCP resources

  • File watching: the in-memory graph stays in sync with editor edits — no restart needed

  • Dry-run support: every write and refactoring tool can preview its changes before applying

See MCP Server.

Search and Ranking

  • Titles and path context, not filenames: a note called 20260903-a7f.md is found by its heading and its position in the graph

  • Two rankers, fused: skim fuzzy matching over title and key, BM25 lexical relevance over title and body, combined with Reciprocal Rank Fusion

  • One ranking everywhere: the CLI, the LSP workspace symbols, and the MCP tools read the same index

  • Incremental: the index is maintained per edit, so long editor sessions stay current

See Notes Search and Search Ranking.

Schema Inference

  • Automatic frontmatter analysis: iwe schema reports field names, type distributions, coverage, and value breakdowns across the workspace

  • Filter-aware: inspect the schema of any subset of documents using the query language

  • JSON/YAML output: pipe schema data into automation, dashboards, or validation pipelines

See IWE Schema and Document Schema.

External Command Integration

  • Configurable command pipeline: connect any CLI tool through a custom template

  • Block-level transformations: apply a command to one section with the surrounding structure as context

  • Template-based input: tune command behavior per content type

See Custom Text Commands.

Markdown Normalization

  • Batch operations: normalize thousands of files in under a second

  • Auto-formatting on save: link titles, header levels, list numbering, and wrapping fixed in place

  • Header hierarchy management: keep document structure consistent as it grows

  • Link title synchronization: keep link text in step with the target document's title

See Text Structure Normalization and Header Levels Normalization.

Hierarchical Notes

  • Inclusion links: the same note can belong to several parents without copying the file

  • Context-aware search: results carry the note's position in the graph, not just its name

  • Inlay hints: see parent context without leaving the document you are reading

  • Hover preview: inspect a linked note inline, frontmatter stripped

  • Flexible organization: flat Zettelkasten and deep directory trees both work

  • Path-based navigation: reach the same content through different conceptual paths

Cross-Editor LSP Integration

  • Native LSP: documented setup for VS Code, Neovim, Zed, and Helix; any LSP-compatible editor can be wired up

  • Consistent behavior: the same features and the same performance in every client

  • No lock-in: switch editors without losing anything

Developer-Focused Architecture

  • Rust core: 20,000 files in under a second

  • Shared core library: the CLI, the LSP server, and the MCP server are thin shells over one domain model, so a new graph operation appears in all three at once

  • Rich graph processing: the transformations above are graph traversals, not text munging

  • Cross-platform: identical behavior on every supported operating system

The shared library is the reason the rest of this page is possible. See Data Model for how documents become a graph.
