What data it sees

Do you need an account

No: the server works without sign-in

A markdown writing workspace your AI can actually write in. Connect an agent to search, read, draft, suggest edits you approve, comment, and publish to WordPress/Ghost/Sanity — in the same live documents you edit, with every agent edit signed and yours to accept or reject. A knowledge base you own and can actually read, not an opaque store.

How to connect

OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.
