Copilot

In short
An AI that assists inside the tool you already use.
In plain English
An assistant embedded in existing software — your documents, spreadsheets, code editor or inbox — suggesting as you work rather than in a separate chat window.
A real example
A spreadsheet suggesting the formula you were about to write, or an email client drafting a reply in the compose box.
Why it matters
Embedded assistance gets used; a separate tab often does not. When comparing options, where the AI lives matters as much as how good it is.
