Copilot in PowerPoint builds and edits the deck itself. You can start from a prompt, through the on-canvas Copilot menu or the Copilot button on the Home tab, or from a Word document with Create presentation from file. With a branded template, Copilot can draft new content straight into your theme. Whatever it produces, you refine with the same menu: rewrite one slide, shorten a wordy one or change the tone of the speaker notes.
Treat the result as a first draft, not a finished deck. Building from a file or a template needs a Microsoft 365 Copilot work licence; Copilot Pro gives a more limited version. A prompt-built deck supports one output language, so an English and a Dutch version are built separately. For images and graphics, you switch to a separate app, Microsoft Designer.
