Markdown CMS AI Knowledge Base Human in the Loop

A #CMS that speaks the same language as #agents .

Your AI assistant already writes in markdown. Vault UI gives those notes a real home — a file system you can browse, audit, edit, and share folder-by-folder with the people you trust. Self-hosted. MIT.

Built for you , your agent , and your friends .

The Problem

Markdown. Multi-user. AI-ready.

Every tool we tried gave us two of those three. We got tired of waiting for the third.

Two Layers One Product

Foundation now. Vision next.

// foundation

A home for your AI's notes.

Your assistant writes the markdown. Vault UI organizes it — folder becomes URL, file becomes page. You read everything in a clean web interface, edit anything you want to correct, and share folders with the people you trust.

// vision

A living dashboard the agent paints.

The agent watches the vault and composes a dashboard around what's relevant right now. Every widget maps back to a real markdown file you can open and edit. The agent paints. You hold the brush.
How It Works

Three things to know.

// 01 · routing

Your folder structure is your URL structure.

Drop a file in a folder — it goes live at the matching URL. Move it, the URL moves with it. Nest as deep as you like. The file system is the sitemap.

file path → live URL
recipes/pesto.md → vault-ui.com/recipes/pesto travel/japan.md → vault-ui.com/travel/japan projects/vault-ui.md → vault-ui.com/projects/vault-ui recipes/pesto.md → vault-ui.com/recipes/pesto recipes/classic-pesto.md → vault-ui.com/recipes/classic-pesto
↳ rename → URL renames automatically
// 02 · rendering

Edit markdown. See it rendered.

Type on the left, watch it render on the right. Headings, lists, bold, links, wikilinks — live as you write. The same markdown you edit is what publishes and what your AI reads.

// 03 · sharing

Share folders with people and agents.

Pick a folder. Pick who can see it — your partner, your client, your housesitter, an AI assistant you trust. They see exactly that, and nothing else. No team plans. No seats.

  • Couples and families sharing a small knowledge base together

  • Freelancers giving one client a clean window into one project

// not for

  • Big companies looking for an enterprise wiki

  • Anyone who wants Notion with extras

  • Teams that need realtime collaborative editing

  • Anyone who hates running their own server
