Show HN: Mnemo – local-first AI memory layer for any LLM (Rust, SQLite,petgraph)
Local-first AI memory layer for any LLM. Persistent knowledge graph, entity extraction, semantic retrieval — no cloud required.
Most LLMs forget everything the moment a conversation ends. mnemo fixes that.
mnemo is a sidecar service that watches every conversation you feed it, extracts named entities and relationships using an LLM, builds a persistent knowledge graph in SQLite, and injects relevant context back into future prompts — automatically, in under 50ms. It works with Ollama (fully local, free), OpenAI, Anthropic, or any OpenAI-compatible API. It ships as a single static binary with zero cloud dependency.
Path A — Docker + Ollama (fully free, recommended)
Path B — Binary (Ollama or OpenAI running separately)
