PowerPoint

Edit your document with Copilot in PowerPoint: Copilot in PowerPoint helps you create, edit, and refine presentations through natural language—right inside your deck. Start a new presentation or build on an existing one by asking Copilot to generate slides, update content, improve layouts, and polish design, all while preserving your formatting, structure, and branding. This experience is available with Microsoft 365 Copilot (Basic). In addition, with Microsoft 365 Copilot (Premium), Copilot can also connect to your brand kit to apply branded templates, insert brand-approved images, and check for brand compliance.
