Microsoft is upgrading Copilot Notebooks to transition from a research tool into an AI-powered workspace for task execution and office automation. The new features aim to enable users to create, edit, and automate workflows directly within the platform, positioning it as a competitor to Google's NotebookLM.

The update introduces task delegation, allowing users to assign specific actions to Copilot rather than just asking questions. Additionally, users can now set up recurring automated workflows, such as daily briefings or weekly status updates, by leveraging project documents and meeting records.

File editing capabilities have been expanded, enabling users to open and modify Word, Excel, and PowerPoint files directly inside Copilot Notebooks using native editing tools. The platform also now generates interactive reports featuring data visualization and filters for deeper analysis.

Audio summary features have been enhanced to support more Microsoft 365 data sources, including Teams chats and Outlook emails. New audio formats, such as critique and debate modes, offer multiple perspectives on the stored content.

Users can select from various AI models, including those from OpenAI and Anthropic, to suit specific needs. The platform now proactively recommends content creation based on existing data. These features are being rolled out in stages via the Frontier preview program.
