ChatGPT opens a BerthTime page. Log in, pick your company (or all your companies) and choose Read only (the safe choice) or Read and write, then click Allow.
Use it in a chat
In a new chat, click “+”, choose BerthTime (under More or Developer mode) and ask, for example “Which of my containers arrive this week?”.
Which ChatGPT plans have developer mode changes often. OpenAI lists Business, Enterprise and Edu workspaces; some Plus and Pro accounts have it too, sometimes limited to read-only tools. If you don't see the switch, your plan or your workspace admin doesn't allow it yet.
ChatGPT Business, Enterprise or Edu: an admin may have to allow developer mode, and an app you create stays private to you until an admin publishes it for the workspace.
