Features
A knowledge base that doesn't rot.
Wikis fail because they depend on discipline. Noesium is built so your team's knowledge stays portable, permissioned, and searchable — by humans and by AI.
Markdown vault
Plain .md files with YAML frontmatter are the source of truth. Your knowledge stays readable and portable — no lock-in, ever.
Role-based access
Users, roles, and groups down to the single document. Every search result and every AI answer respects who's asking.
AI over your knowledge
Chat with your vault. Model-agnostic by design: plug in the best LLM available at any moment, swap it when a better one ships.
Air-gap first
A single container with no outbound calls of its own — the only egress is the LLM endpoint you configure, which can run on your own hardware. Your data never asks permission to stay home.
Version history
Every change tracked with author and timestamp. Diff any two versions, see who changed what, restore in one click.
Dev engine soon
CI/CD integration that keeps docs aligned with your code: analysis on every PR, auto-updated pages on merge, ADRs captured before knowledge evaporates.
FAQ
Frequently asked questions
The short answers. Everything here is also in llms.txt for the machines.
How is Noesium different from Confluence or Notion?
Noesium is fully self-hosted and your knowledge lives in plain Markdown files with YAML frontmatter — no proprietary format, no cloud dependency, no lock-in. It ships as a single Docker container, makes no outbound calls of its own, and adds role-based permissions, full version history, and AI chat on top of your own infrastructure.
Does Noesium work in air-gapped or offline environments?
Yes. Noesium is air-gap first: it runs as a single container that makes no outbound calls of its own and works in fully disconnected environments. The only egress is the LLM endpoint you choose to configure — point it at a locally hosted model and nothing ever leaves your infrastructure.
What format is my data stored in? Is there lock-in?
The source of truth is a vault of plain .md files with YAML frontmatter. Your knowledge stays readable and portable with any text editor — you can leave at any time and take everything with you.
Which AI models does Noesium support?
Noesium is model-agnostic: you can plug in any LLM provider — cloud APIs or locally hosted models — and swap it whenever a better one ships. Every AI answer respects the asking user's document permissions.
How much does Noesium cost?
Noesium is free for individuals and small teams, forever. Larger organizations will need a commercial license. Public release is upcoming — join the newsletter on noesium.app to be notified at launch.
How do I install Noesium?
One command: docker compose up -d. It is a single container on your own infrastructure — no cloud account, no phone-home. The download will be available at launch.
