An app connects ChatGPT to a tool you already use. Once connected, ChatGPT can search and read there, bring live information into a chat, and, with permission, take actions like drafting an email or updating a record.
An app works as you: it signs in with your account and reaches only what you can already reach. For each app you choose a permission: Always ask, Allow read actions, Allow low-risk actions, or, for some apps, Allow all actions. On Business, admins decide which apps the workspace may use, and app data is not used for training by default.
