Markdown CMSAI Knowledge BaseHuman 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.

How It Works
// 01 · routing

Folders become URL structure.

Your assistant writes the markdown. Vault UI organizes it — Each file becomes a page.

  • File recipes/pesto.md
    Live URL vault-ui.com/recipes/pesto
  • projects/vault-ui.md vault-ui.com/projects/vault-ui
  • recipes/classic-pesto.md vault-ui.com/recipes/classic-pesto
// 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 parts 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.
