Microsoft Copilot is Microsoft’s AI assistant, powered by OpenAI’s models and woven into Microsoft 365 — Word, Excel, PowerPoint, Outlook, Teams, and more. For businesses already running on Microsoft’s stack, it’s the AI integration with the least friction to get started.

What it is

Microsoft Copilot refers to two related but different products. There’s the free Copilot chat assistant at copilot.microsoft.com (and built into Windows), which is essentially a web-connected chat experience using GPT-4o. Then there’s Microsoft 365 Copilot — an add-on for business Microsoft 365 subscriptions — which embeds AI directly into Word, Excel, PowerPoint, Outlook, Teams, and other apps with access to your organization’s data. These are distinct products with different pricing.

What it’s best at

• Drafting documents in Word with context from other files in your organization
• Summarizing long email threads in Outlook with one click
• Generating PowerPoint presentations from a written prompt or Word document
• Analyzing data and writing formulas in Excel
• Summarizing Teams meetings and creating action-item lists from transcripts
• Searching across your company’s Microsoft 365 data (SharePoint, Teams, emails) to answer questions

How operators use it

Operators on Microsoft 365 Business plans use Copilot to cut down time on routine document work. Common patterns: summarize last week’s email threads before a meeting, ask Copilot to draft a proposal by pulling in specs from a SharePoint folder, or generate a first-draft PowerPoint from a Word document outline. The Teams integration is particularly useful — Copilot can join a meeting, transcribe it, and produce a summary with decisions and action items, which saves significant time for anyone running recurring team calls.

Getting started & pricing

• Free Copilot: Available at copilot.microsoft.com, built into Windows 11 — web-based chat, no Microsoft 365 data access
• Microsoft 365 Copilot ($30/user/month): Requires an existing Microsoft 365 Business Standard or higher plan; adds Copilot to all M365 apps with org data access
• Copilot Pro ($20/month, personal): Copilot in personal Microsoft 365 apps, priority access to newer models

If you have a Microsoft 365 Business subscription, check your admin center to see if Copilot is available or purchasable. For solo operators, the free tier at copilot.microsoft.com is a quick way to test the experience.

Bottom line

Microsoft Copilot is most valuable when you’re already deep in the Microsoft 365 ecosystem and deal with high volumes of email, documents, and meetings. The $30/user/month add-on is a meaningful expense for small operators, so it’s worth auditing which use cases (meeting summaries, document drafts, email triage) would actually save your team time before committing. For businesses not on Microsoft 365, the free Copilot is a capable chat assistant but offers no special advantage over ChatGPT or Claude.
