What's the difference between M365 Copilot and ChatGPT?
Copilot is grounded in your work data and runs inside Microsoft 365 apps. ChatGPT is general-purpose — great for writing, brainstorming, coding — but doesn't see your files unless you paste them.
When should I use Copilot instead?
When the task needs your files/emails/meetings, the data must stay in your org, or you want to act inside a M365 app.
Can I use both?
Yes — commonly Copilot for grounded work content, ChatGPT for open-ended thinking. It's task by task.
