Show HN: I replaced vector databases with Git for AI memory (PoC)
DiffMem: Git-Based Differential Memory for AI Agents DiffMem is a lightweight, git-based memory backend designed for AI agents and conversational systems. It uses Markdown files for human-readable storage, Git for tracking temporal evolution through differentials, and an in-memory BM25 index for fast, explainable retrieval. This project is a proof-of-concept (PoC) exploring how version control systems can serve as a foundation for efficient, scalable memory in AI applications. At its core, Dif
