Show HN: I replaced vector databases with Git for AI memory (PoC)
Git Based Memory Storage for Conversational AI Agent - Growth-Kinetics/DiffMem
At its core, DiffMem treats memory as a versioned repository: the "current state" of knowledge is stored in editable files, while historical changes are preserved in Git's commit graph. This separation allows agents to query and search against a compact, up-to-date surface without the overhead of historical data, while enabling deep dives into evolution when needed. This approach shines for long-horizon AI systems where memories accumulate over years: it scales without sprawl, maintains auditability, and allows "smart forgetting" through pruning while preserving reconstructability.
