Microsoft has unveiled major upgrades to its Microsoft 365 Copilot platform, designed to transform AI from a conversational assistant into a productivity partner capable of both advanced research and workflow automation.
A central part of the update is the expansion of Copilot’s research capabilities. The new Critique feature allows multiple AI models to work together: one model generates a response while another checks for accuracy and quality before it reaches the user. Complementing this, the Council interface enables side-by-side comparison of responses from different models, helping users make more informed decisions.
Corporate Vice President Nicole Herskowitz said, “Having various different models from different vendors in Copilot is highly attractive – but we’re taking this to the next level, where customers actually get the benefits of the models working together.”
Microsoft is also introducing Copilot Cowork, an AI agent that can manage tasks across Microsoft 365 applications, including Outlook, Teams, and OneDrive. Users can issue natural language instructions, and Cowork can send emails, schedule meetings, create documents, post in Teams, browse the web, and manage files. Sensitive actions require user approval, ensuring control and transparency.
In addition, Copilot’s automation capabilities are being embedded across Microsoft 365 tools. AI-driven workflows can now execute scheduled tasks and repetitive routines, reducing manual effort and streamlining collaborative productivity.

The rollout of these features marks a significant step in Microsoft’s ambition to make AI an integrated, practical tool for knowledge work, task execution, and workflow efficiency.
