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

Mnemo is a local-first AI memory layer that runs as a standalone Rust service to add persistent knowledge graph capabilities to any LLM application. It extracts entities and relationships from conversations, stores them in SQLite, and injects relevant scored context back into prompts—all without cloud dependency or vendor lock-in. The tool works with Ollama, OpenAI, Anthropic, or any OpenAI-compatible API, and differentiates itself through multi-hop graph traversal and ranked retrieval compared to simpler in-memory alternatives.
