Huginn & Muninn by RunarForge

Your AI coding tools finally remember.

Huginn & Muninn gives AI assistants persistent memory across sessions, tools, and your entire codebase — so every session starts where the last one ended.

The Problem

Every AI coding session starts from zero.

Context vanishes

Close a session and everything is gone. The next session has no idea what you just built, what you decided, or what went wrong. You explain the same context again and again.

?

The codebase is a black box

Starting work on an unfamiliar project means hours of reading files before you can ask your AI assistant a meaningful question. It has no idea how authentication works, what patterns you follow, or where the business rules live.

Knowledge walks out the door

When a developer leaves or switches teams, their understanding of the system leaves with them. There is no persistent, searchable record of why things were built the way they were.

The AI has access to your code.
It just has no memory of your project.

The Solution

Persistent memory for the AI age.

Huginn & Muninn works silently alongside your AI tools — remembering, learning, and surfacing exactly what your AI needs to be genuinely useful from session one.

Muninn

The Memory

Stores decisions, bug fixes, patterns, and business rules with full context. Searches by meaning — not keywords. Survives every session close, context reset, and compaction event.

Works with Claude Code, Cursor, Windsurf, and any MCP-compatible AI tool.

Huginn

The Scout

Flies across your codebase and extracts architectural knowledge. No code execution, no install required — works on any project in any state. Understands 8 languages.

Produces a complete architecture summary in minutes, not hours.

Curator

The Oracle

Answers questions about your project with citations and confidence scores. Onboards a new developer or AI session in seconds. Always cites its sources. Never guesses.

If it doesn’t know, it tells you — and tells you what to do next.

How It Works

Set up once. Works forever.

01

One command

npm install -g @runar-forge/hm

Add to your AI tool’s settings.json. That’s the entire setup.

02

Understand your codebase

runar crawl /your/project --project my-app

Huginn analyzes your project topology, scores files by architectural importance, and extracts patterns — without running a single line of code.

03

Memory that grows

Every decision, every bug fix, every pattern discovered is saved to Muninn. Every new session starts with full context. Curator answers your questions from real project knowledge.

Built For

For developers who are tired of starting over.

The Developer

You work on multiple projects. You use AI tools daily. You’ve watched context disappear mid-task and rebuilt the same understanding from scratch more times than you can count. Huginn & Muninn gives you continuity.

The Engineering Team

Your team’s knowledge lives in developers’ heads. When someone leaves, understanding leaves with them. Muninn captures what your team learns — decisions, patterns, gotchas — and makes it available to every developer and every AI session.

The Engineering Manager

You want your team to move faster without cutting corners. Huginn & Muninn reduces the time developers spend re-orienting on unfamiliar code, and gives AI tools the project context they need to give useful answers from session one.
