What Is Microsoft Copilot in 2026?

Microsoft Copilot is Microsoft’s AI assistant embedded in the Microsoft 365 suite — Word, Excel, Outlook, PowerPoint, Teams, and SharePoint. Microsoft says 90% of the Fortune 500 now use Copilot (March 2026).

In March 2026, Microsoft announced Wave 3, a major Copilot update that moves it from conversation toward agents that execute multi-step workflows across Microsoft 365. Wave 3 brought Claude into mainline Copilot chat alongside OpenAI models, expanding the model choice Microsoft first introduced in Researcher and Copilot Studio in late 2025. Copilot Cowork, built with Anthropic, handles longer-running tasks on your behalf.

What Copilot Does Best in 2026

Microsoft 365 Deep Integration

Copilot is embedded directly in Word, Excel, Outlook, PowerPoint, Teams, and SharePoint. It reads your emails, understands your documents, knows your calendar, and has access to your organization’s SharePoint data — all within Microsoft’s enterprise security boundary. This organizational context is what Copilot calls Work IQ, and it is what makes the tool fundamentally different from standalone AI assistants like Claude or ChatGPT.

Copilot Cowork — Multi-Step Work Agent

The centerpiece of Wave 3, Copilot Cowork was built in close collaboration with Anthropic and carries out multi-step tasks across Outlook, Teams, Word, Excel, PowerPoint, and SharePoint. You describe an outcome and Cowork works toward it. It launched on Claude models and now offers a model selector that includes newer Claude and OpenAI models.

Microsoft’s examples include prompts like “Prep me for tomorrow’s client QBR,” where Cowork gathers relevant emails and files, drafts a briefing and builds a deck. Check Microsoft’s Cowork documentation for what it can do without your approval.

Cowork reached Frontier customers on March 30, 2026 and became generally available worldwide on June 16, 2026 for users with a Microsoft 365 Copilot license. Usage is billed in Copilot Credits, and admins must turn it on.

Model Choice — OpenAI and Anthropic Models

Wave 3 brought Claude into mainline Copilot chat alongside OpenAI models. Copilot can pick a model automatically (“Auto”), and in several experiences you can choose a specific OpenAI or Anthropic model yourself, including a model selector in Excel. Which models you see depends on your license, region and admin settings.

Copilot Studio lets builders pick from current OpenAI and Anthropic models (including Claude Opus 5.5 and GPT-6 Sol as of September 2026), subject to admin settings and region.

Critique and Council — Multi-Model Verification

Two research verification features launched in Researcher on March 30, 2026. Critique has one model draft a report while a second model reviews it for source reliability, completeness and citation accuracy; it is the default when Researcher is set to Auto. Council runs models side by side and uses a judge model to highlight agreements and differences. Microsoft reported Researcher with Critique scoring 57.4 on the DRACO benchmark, a 13.8% improvement over Perplexity Deep Research in its own testing.

Excel — Data Analysis and Formula Generation

Copilot in Excel generates complex formulas from plain-English descriptions, analyzes data, creates pivot tables and charts automatically, and with Wave 3 can now execute multi-step Excel workflows autonomously. Finance professionals and analysts can describe what they need — “build a 12-month P&L forecast with adjustable assumptions” — and Copilot builds it. The manual model selector also lets analysts choose Claude specifically for complex financial reasoning tasks directly within the spreadsheet.

Outlook — Email Intelligence

Copilot summarizes long email threads, drafts replies in your writing style, prioritizes your inbox, and with Wave 3 can now schedule from chat and send emails directly from the Copilot interface. Copilot Chat enhancements include inbox and calendar awareness — it can see your calendar context when drafting responses and scheduling meetings.

Teams — Meeting Intelligence Upgraded

Copilot takes notes in Teams meetings and produces structured summaries with action items. Video recap (English only for now) turns a recorded meeting, typically at least 10 minutes long, into a narrated highlight reel. Audio recap produces spoken summaries in English, Chinese, French, German, Italian, Japanese, Portuguese and Spanish and requires transcription.

PowerPoint — Presentation Generation

Copilot generates entire slide decks from documents or briefs, and Wave 3 adds the ability to standardize formatting across all slides at once — automatically updating fonts, font sizes, and bullet styles throughout a presentation. Create directly from Copilot Chat, including full PowerPoint presentations, without opening PowerPoint first.

Agent 365 — Enterprise Agent Management

Generally available since May 1, 2026 ($15/user/month and included in E7), Agent 365 is Microsoft’s control plane for managing AI agents across the organization: an agent registry, Entra ID access controls, visualization of agent activity, interoperability, and security. It is a governance layer aimed at IT leaders deploying AI at scale.

Third-Party Agent Integrations

Wave 3 opens Copilot Chat to third-party agents from Adobe, Monday.com, Figma, and others through open standards including MCP. Organizations can connect external tools directly into the Copilot environment, letting AI coordinate across a broader toolkit rather than treating each application as a separate task.

Where Copilot Falls Short

Cost — Higher Than Standalone Assistants

Copilot Business lists at $21/user/month on an annual plan ($25.20 month-to-month) on top of a Microsoft 365 Business plan, and Microsoft is running a first-year promotion at $18/user/month through December 31, 2026. Business Standard and Business Premium bundles with Copilot are sold at $23.50 and $32/user/month. The enterprise Microsoft 365 Copilot add-on is $30/user/month. Cowork usage is billed separately in Copilot Credits. For individuals or small teams, this is a meaningful extra cost compared with $20/month standalone plans for Claude or ChatGPT. Microsoft 365 E7 at $99/user/month bundles more, but is a substantial budget commitment.

Writing Quality Outside Office Apps

For standalone writing tasks — drafting proposals, writing emails from scratch, long-form content — reviewers often find Claude and ChatGPT produce more polished output. Copilot works best when it has document context to draw on.

Limited Value Outside Microsoft Ecosystem

Copilot is designed around Microsoft 365 and doesn’t natively work inside Gmail, Docs or Sheets. If your organization’s primary environment is Google Workspace, Notion or other non-Microsoft tools, evaluate it with that in mind.

Cowork Costs Are Usage-Based

Cowork has been generally available since June 2026, but it isn’t flat-rate. Each task consumes Copilot Credits based on model use, data retrieval, tool calls and runtime. Microsoft lists pay-as-you-go at $0.01 per credit, and admins can set spending caps per tenant, group or user. Budget for it separately from the $30 license.

Microsoft Copilot Pricing (checked September 28, 2026)

Who Should Use Microsoft Copilot

• Any professional whose work centers on Word, Excel, Outlook, PowerPoint, or Teams
• Finance and analyst teams who work heavily in Excel — the model selector for Claude vs OpenAI is worth trying for financial analysis
• Managers and executives who need meeting intelligence — video and audio recaps save significant time across large Teams organizations
• Enterprise IT teams who need governance, audit trails, and security controls for AI deployments
• Organizations ready to move from AI assistance to AI execution with Copilot Cowork
• Organizations already on Microsoft 365 E5 — E7 at $99/user/month ($90.45 without Teams) adds Copilot, Entra Suite and Agent 365

See our Claude AI review for more on Claude for Excel, which is available as a standalone add-in for professionals who want Claude’s Excel capabilities without the full Copilot subscription.

Who Should Consider an Alternative

• Google Workspace user? Gemini integrates natively with Gmail, Docs, Sheets, Slides, and Meet — Copilot is designed around Microsoft 365
• Need the best standalone writing? Claude is often preferred for standalone writing outside Office apps
• Individual professional not using M365? ChatGPT Plus at $20/month gives you more flexibility and breadth without requiring a Microsoft ecosystem
• Research-heavy work? Perplexity AI provides faster, sourced, real-time research that Copilot does not match

Our Verdict

Wave 3 moves Microsoft Copilot from a capable assistant toward agents that do multi-step work. Copilot Cowork, model choice between OpenAI and Anthropic, Critique and Council in Researcher, and Agent 365 governance make it a strong enterprise AI platform in 2026.

For professionals whose work runs on Microsoft 365, Copilot is the most natural AI upgrade to evaluate. The Excel, Outlook, and Teams integrations are the main draw, and Cowork’s multi-step workflows are worth a pilot.

The cost remains the primary consideration, including usage-based Cowork credits. If your organization is not deeply embedded in Microsoft 365, Copilot delivers less value.
