Microsoft PowerPoint Copilot
| Developer | Microsoft Corporation |
| Supported Platforms |
|
| Language Support | 40+ languages including English (US/UK), Chinese (Simplified/Traditional), Japanese, Korean, Arabic, Dutch, French, German, Italian, Portuguese, Spanish, Russian, Vietnamese. Availability varies by region. |

What is Copilot in PowerPoint?
Copilot in PowerPoint is an AI-powered assistant integrated into Microsoft PowerPoint as part of the Microsoft 365 Copilot ecosystem. It transforms how you create presentations by enabling natural-language commands to generate, design, and refine slide decks instantly.
Instead of building slides manually, simply ask Copilot to create a presentation on any topic, import content from Word, PDF, or Excel files, apply professional design themes, generate speaker notes, and summarize existing presentations. This dramatically accelerates productivity for educators, business professionals, trainers, and anyone who needs compelling presentations quickly.
How Copilot in PowerPoint Works
Open PowerPoint, click the Copilot button, and type a simple instruction like "Create a 10-slide presentation about sustainable agriculture". The AI will propose slide topics, generate relevant content, add images and speaker notes, apply your organization's template, and produce a complete draft deck in seconds.
You can also start from existing documents — Copilot extracts structure and content from Word files or PDFs to convert them into polished presentations. Once generated, refine slide order, adjust layouts, modify branding, and ask Copilot to summarize, rewrite, or reorganize content as needed.
Because it operates within the Microsoft 365 ecosystem, Copilot seamlessly accesses files from OneDrive and SharePoint while respecting organizational templates and branding guidelines. Multi-language support enables prompts and output in dozens of languages, though English delivers the strongest performance.
Key Features
Create complete presentations from natural-language prompts or existing files (Word, PDF, TXT, Excel) with automatic content structuring.
Automatically apply slide layouts, design themes, organizational templates, and branding with professional images and speaker notes.
Summarize existing presentations and chat with your deck to extract key takeaways, insights, and answers to specific questions.
Work in 40+ languages with prompts and responses, though English provides the highest quality output.
Seamlessly access files from OneDrive and SharePoint, preserve organizational templates, and leverage Microsoft Graph for contextual intelligence.
Download or Access Link
How to Use Copilot in PowerPoint
Ensure you have a qualifying Microsoft 365 plan and the Microsoft 365 Copilot add-on license. Your administrator must assign the Copilot license to your account.
Open PowerPoint (desktop or web version) and sign in with your work or school account that has Copilot access enabled.
Click the Copilot icon in the Home tab or ribbon to open the AI assistant panel.
Choose "Create a new presentation" or "Create a presentation from file". Enter your prompt (topic, slide count, target audience) or attach a Word/PDF/Excel file for content extraction.
Review the slide topics Copilot proposes, make adjustments if needed, then click "Generate slides". Wait for the AI to create your draft deck.
Use the Designer pane to refine layouts, apply branding, change visuals, and edit speaker notes. For existing decks, ask Copilot to summarize, add slides, rewrite content, or answer questions.
Review all slides for accuracy, branding consistency, and logical flow. Make manual edits as needed since AI-generated content requires human verification. Save and share your polished presentation.
Important Limitations
- Feature availability varies by region, license type, and rollout status. Some capabilities (certain file types, advanced features) remain in preview.
- AI-generated content requires manual review and editing. Always verify formatting, factual accuracy, and slide flow before presenting.
- Language quality outside English may be lower. Some languages and locales are not yet fully supported.
- Internet connection required — Copilot operates cloud-based and needs connectivity to OneDrive/SharePoint for full functionality.
