Memhub LLM Wiki Guide — AI skill for Claude Code

XTrace MemHub — LLM-Wiki Mindmap Guide

Turn your **ChatGPT**, **Claude**, and **Gemini** history into an **Andrey Karpathy's LLM-Wiki mindmap** — structured Markdown you can browse in Obsidian-style tools and explore as a graph in MemHub.

**MemHub** is your context control panel for AI agents. This guide walks through exporting chat history, importing it into MemHub, exploring the **Mindmap**, and downloading a **Markdown ZIP** (“Mindmap Markdowns”) for your second brain — without writing code or using Claude Code.

MemHub extracts AI memory and context from your chats, stores it in an encrypted vector database, and organizes it in a file layout that tools like Obsidian work well with.
