Copilot Cowork is an extension of Microsoft 365 Copilot that’s designed specifically for long-running, multi-step work rather than just quick prompts or one-off content generation.

While Microsoft 365 Copilot is your general-purpose AI for work—embedded in apps like Word, Excel, Outlook, and Teams—Copilot Cowork focuses on helping you:

• Delegate outcomes, not just tasks: You describe the result you want, and Copilot Cowork creates a plan to get there.
• Coordinate across tools and files: It reasons across your Microsoft 365 environment, connecting steps and coordinating tasks.
• Carry work forward over time: It supports ongoing workflows, not just single interactions.

Copilot Cowork is built on a multi-model advantage, bringing together AI innovation from across the industry and grounding it in your organization’s data (Work IQ) with Enterprise Data Protection. That means it operates within your existing security and risk boundaries, so teams can experiment and scale with more confidence.

In short, Copilot Cowork helps you reimagine how work gets done by moving from “ask-and-answer” AI to AI that can take real action across everyday workflows.

Copilot Cowork is built to support both one-off tasks and repeatable workflows that span multiple steps, people, and tools.

Examples of what it can help with include:

• Planning and scheduling: Using built-in skills (like calendar management and daily briefings), Copilot Cowork can help organize meetings, timelines, and follow-ups.
• Creating and refining deliverables: It can help draft, structure, and iterate on documents, presentations, and reports based on your files and context.
• Executive and stakeholder preparation: It can pull together materials, summarize key points, and prepare briefings for leadership reviews.
• Repeatable processes: For example, a monthly budget review workflow—gathering data, preparing summaries, and tracking actions over time.

Organizations like Capital Group, which had early access, report value in areas such as planning, scheduling, creating deliverables, and preparing for executive reviews. As their SVP of Enterprise Technology put it, the benefit is less about generating content and more about connecting steps, coordinating tasks, and following through across everyday workflows.

Because Copilot Cowork operates on your enterprise data and within your security and risk boundaries, you can test and scale these scenarios while keeping governance in place.

Researcher in Microsoft 365 Copilot is designed to help you tackle complex questions by synthesizing information across multiple sources and producing cited, well-reasoned analysis you can act on.

Recent updates add multi-model intelligence and two key capabilities:

1. Critique feature
   This feature uses a combination of models from Frontier labs, including Anthropic and OpenAI, to separate generation from evaluation:
   • One model plans the task and creates an initial draft.
   • A second model acts as an expert reviewer, focusing on refinement before the final report is produced.

   The impact is measurable: Researcher now scores 13.8 points higher on the DRACO benchmark (Deep Research Accuracy, Completeness, and Objectivity), which is an industry standard for deep research quality.

2. Model Council
   With Model Council, you can compare responses from different models side by side. This lets you see:
   • Where models agree or diverge.
   • What each model uniquely contributes.

   In practice, it’s like having multiple researchers at your fingertips, giving you a more rounded view before you make decisions.

Together, these capabilities help organizations rethink how they approach deep research—moving from single-model answers to a more robust, multi-model review process that emphasizes accuracy, completeness, and objectivity.
