AI Memory

AI Memory is a long-term memory system that lets Home Assistant's Assist agents store and recall facts and preferences. Memories persist across conversations and are found through vector similarity search, with tools for adding, searching and deleting them exposed to every Assist agent. The same actions are available as services, so automations and scripts can use them and capture the result in a response variable. Memories are grouped by wing and room, and each one is either private to one agent or shared by all agents. Data stays on the Home Assistant instance in a local database. Embeddings come from an Ollama server, an OpenAI-compatible server, or a built-in TF-IDF engine that needs no server, and the provider, model and memory limit are chosen in the UI setup.
