## Basic Info
- **Type**: 产品 / AI Memory Tool
- **GitHub**: 1.2k stars
- **Category**: Camp 2 — Context Substrate
- **Infrastructure**: MilvusZilliz 团队)
- **Website**: Zilliz 生态
## Summary
来自 Milvus 团队Zilliz的 Markdown 优先记忆工具。记忆是 .md 文件人类可读、可编辑、可版本控制。Milvus 作为"影子索引"从文件派生,完全可重建。
## Core Philosophy
**文件是真相来源。向量搜索只是文件之上的访问层。**
## Architecture
- **第一层**语义块semantic chunks
- **第二层**完整段落full sections
- **第三层**原始转录raw transcripts
- 三层渐进披露progressive disclosure
## Key Significance
这个工具来自 Zilliz——向量数据库公司。他们交付的记忆系统中他们自己的产品Milvus在文件下游。这是一个有意义的让步——承认了真相来源实际在哪里。
