## Summary
基于 RAG 的个人第二大脑系统:自动从任意 URL 摄取内容(文章/tweets/YouTube/PDF向量嵌入存储语义搜索返回 ranked 结果+来源引文。支持其他 agent 工作流查询。
## Architecture
```
URL Drop → Content Fetch → Chunking → Embedding → Vector Store
Query → Semantic Search → Ranked Results + Citations
```
## Key Properties
- 零摩擦摄入Telegram/Slack 发 URL 即可
- 语义搜索:自然语言查询,非关键词匹配
- Source-grounding每个回答附带原文引文
- 主动供给:其他工作流可自动查询知识库
## Compared To
- [[NotebookLM]]NotebookLM 侧重已有文档管理,本概念侧重实时 URL 摄入+语义搜索
- [[双层记忆架构]]本概念是外部知识管理vs 双层记忆是 agent 自身经验积累
