Mnemo – local-first AI memory layer for any LLM (Rust, SQLite,petgraph)

Mnemo is a local-first, open-source memory layer for LLMs, built in Rust with SQLite and petgraph, that enables AI assistants to persistently store, recall, and reason over structured knowledge graphs without relying on cloud services. It is designed for developers building privacy-focused, offline-capable AI applications who need their models to maintain long-term context and relationships between entities. The project is interesting because it combines the performance of Rust with graph-based memory, offering a self-hosted alternative to proprietary memory systems while keeping user data fully under local control.
