For those in orgs that do, how do you track use of all these new AI services?

So with everybody wanting to use their own flavour of the month AI agent we have requests for Claude, ChatGPT, Grok, Gemini, Copilot, Cursor, Github Copilot etc.

While we have enterprise versions of almost all of them and we control as much as possible how everybody uses them (domain verification etc), my concern is that each one of these has hundreds of integrations.

Excel/Outlook/Sharepoint add-ins, Chrome extensions, Google Workspace connectors, Zoom plugins.

How do you keep abreast of the spiderweb of integrations that inevitably forms? How do you map what integrates with what?
