Say you connect Google Ads, Meta and LinkedIn to the same assistant. Do you keep everything in one long conversation, or open a new chat for each platform and each task?
My view is separate chats for anything that changes money, and one shared chat for the thinking. Long threads pile up old numbers, half-finished tests and earlier instructions, so by week three the model can quietly mix a Meta budget discussion with a Google bid strategy from last month. A new chat per platform keeps the context clean and makes it obvious which account a preview belongs to.
The counter-argument is fair, though. Cross-channel questions like where to move budget get worse when each chat only sees one platform. I'd still keep the action chats separate and paste a short summary into a planning chat when you need the big picture.
