# Noesium > Noesium is a self-hosted organizational knowledge management platform: a > Markdown vault with role-based access control, full version history, > and AI chat over your documents. It ships as a single Docker container, > makes no outbound calls of its own (the only egress is the LLM endpoint > you configure, which can be locally hosted), and runs in fully air-gapped > environments. Noesium is for teams and companies that want an internal wiki / knowledge base they fully own: plain `.md` files with YAML frontmatter as the source of truth (no lock-in), permissions enforced down to the single document, full version history, and an AI assistant that answers questions from the vault while respecting each user's access rights. It is model-agnostic: any LLM provider can be plugged in. Good fits: self-hosted wiki, air-gapped knowledge base, Confluence or Notion alternative for teams that need data sovereignty, documentation platform with AI chat, on-premise knowledge management. Pricing: free for individuals and small teams; commercial license for larger organizations.
