Build an Atrium app with AI

One minimised file with everything an AI tool needs: how to work, the hard rules, the full app contract and the design system. Upload it to any LLM, then describe your app.

ATRIUM-AI-BUILD.mdMarkdown
  1. Upload the file to ChatGPT, Claude, Cursor or any AI tool (or paste its contents).
  2. Describe the app you want in plain English.
  3. Let the AI ask you for the API key when it needs one.

What an Atrium app is

View .md

An Atrium app is an HTTPS service you run (yourself, or later on Atrium Hosting). COHO never contains your business logic.

Manager connects the app in the Store
  -> COHO POSTs signed lifecycle.setup to you
  -> you store the API key + signing secret
  -> COHO may POST signed events/schedules
  -> you call Public API v1.1 with the API key
  -> you write Store logs
  -> optional: COHO loads your quick view URL in an iframe

Same runtime contract for COHO-built apps, private org URL apps, and (later) Partners.
