A writing companion for Claude. Stanza opens any folder of markdown files — the calm, collaborator-friendly surface for the knowledge base you’re building with AI.
Your AI writes markdown into a folder. Stanza renders it beautifully and lets you review, comment, and direct the next round — without leaving the document. AI comments become the protocol between you and Claude.
The people around you — teammates, clients, family — just want to read the thing. They’re not going to install a developer tool or learn a new app. Stanza is what you give them. One click, no account, no setup.
No database. No proprietary format. No cloud lock-in. Stanza writes exactly the markdown you’d write by hand — round-trip faithful, byte-for-byte. If Stanza disappeared tomorrow, your files would still open in any editor.
If you’re building a knowledge base with Claude, it’s probably working well — for you.
The problem is the people around you. Teammates, clients, collaborators. They often won’t install the developer-friendly tools you love, and bounce off your beautiful markdown vault the moment they see it.
Stanza is the app you give them. It opens your vault in a clean, familiar editor. No setup, no account, no lock-in. Your markdown stays yours, on your disk, exactly as you wrote it — and theirs stays theirs.
Stanza is quietly opinionated about who it’s for. You’ll probably recognise yourself in one of these.
