Copilot

Copilot is the name Microsoft uses for the AI assistants woven into its products, from Windows and Office to its developer and business tools. Much of the experience is powered by OpenAI’s models.

The idea is to place AI help right where work already happens — drafting an email, summarising a document, building a spreadsheet formula — rather than in a separate app. Microsoft has been reorganising its various Copilot products into a more unified whole, and adding background agents that can carry out tasks like scheduling on their own.

Because Copilot rides on software that is already installed in countless offices, it is one of the main ways AI is reaching everyday business work.
