Mimir is a local-first personal AI assistant for technically inclined users who want to run an assistant on their own hardware. It connects to an OpenAI-compatible inference server, including Ollama, llama.cpp, or MLX-LM, and provides streaming chat through a React web interface. Conversations are stored in PostgreSQL, with a three-tier memory system combining editable semantic memory, episodic recall, and a working conversation window. That mix makes Mimir relevant to solo users who want continuity across chats and control over where inference runs, rather than a ready-made mobile assistant.

Document retrieval and tool use are central to its scope. Mimir can index Markdown and PDF files for retrieval-augmented search, while its MCP tool loop supports multi-step work involving web search, calendar lookups, and Kubernetes operations. Write actions require approval before execution, a useful boundary for users who want automation without unrestricted changes. Scheduled calendar morning briefings and RSS digests are also available when the associated external services are configured. The listed connections include CalDAV, SearXNG, Miniflux, Kubernetes, and ntfy, alongside local inference options. This ecosystem suits users comfortable managing those components; buyers seeking a broad, ready-to-connect assistant ecosystem may prefer another product.

Mimir is open source and has a free plan, with community and documentation listed as support channels. Its self-hosted, own-hardware approach offers technical users flexibility, but it also places setup and operation with the user. There are no mobile apps or browser extension, so it is a less natural fit for people who expect access through those interfaces. Choose Mimir for local inference, persistent memory, document search, and approval-gated tools; look elsewhere if mobile access or a less technical setup is essential.
