At the heart of it is Agent Mode, a new Copilot feature rolling out to Word, Excel, and soon PowerPoint. Just days ago, Anthropic showed off a Claude chatbot trick that can create or edit Excel, PowerPoint, Word, and even PDF files without you opening them. Claude will soon coexist inside Office alongside OpenAI’s GPT models, meaning Microsoft’s productivity suite is about to be an AI battleground. For now, Office Agent is debuting for Microsoft 365 Copilot customers and Personal or Family subscribers on the web, with desktop updates coming soon. Will Microsoft’s Agent Mode actually save time for office workers, or will it just create new problems as people struggle to verify AI-generated reports and presentations?
