LLM Wiki Template — 会自己更新的 AI 第二大脑

A starter template for a self-updating second brain: you drop in raw material, an AI reads it and keeps a structured, cross-linked wiki up to date, and you just ask it questions. Based on Andrej Karpathy's "LLM wiki" pattern. Works with Obsidian (to view) + Claude Code (to maintain it).

你的笔记是不是存了就没再打开过？这个模板让 AI 帮你整理、维护一个会自己长大的知识库。你只要做两件事:丢资料、问问题。

What's in here

• CLAUDE.md — the rules the AI follows (ingest / query / lint). This is the engine.
• README.md — this file.

Quick start (5 steps)

1. Download this template, or click Use this template / clone it into a new folder.
2. Open the folder in Obsidian as a vault (Open folder as vault).
3. Create two folders inside it: raw/ (your source material) and wiki/ (the AI writes here).
4. Open the folder with Claude Code. Beginner-friendly way: install the Antigravity IDE and add the Claude Code plugin — you get a file tree on the left and a chat box on the right, no terminal needed.
5. Use it:
   • Drop an article or note into raw/, then tell the AI: "整理进 wiki" (or "ingest the new files"). Watch it build pages in wiki/, update index.md, and write to log.md.
   • Ask it questions — it answers from your wiki and files good answers back.
   • Open Obsidian's Graph view to see your knowledge connect.

That's the whole loop. Every source you add makes it richer; the AI does the organizing and maintenance you'd normally abandon.
