Microsoft Copilot is an AI assistant available on the web, desktop and mobile devices, with additional features built into Microsoft 365 applications. It can answer questions, draft text, analyze files, search the web and help users move from an idea to a finished piece of work.
What is Microsoft Copilot?
Copilot is Microsoft’s name for a family of AI experiences rather than one identical product. The consumer Copilot app provides conversational assistance for everyday tasks. Copilot inside Microsoft 365 adds help within Word, Excel, PowerPoint, Outlook and OneNote. Business versions use separate licensing and data-protection rules.
This distinction matters because features, prices and privacy terms can differ depending on the account and product being used.
What can Copilot do?
The standalone assistant can explain topics, draft and rewrite text, summarize information, work with uploaded files and return web-connected answers. Microsoft also lists deeper reasoning, research, visual answers, image creation, audio generation and connectors to services such as OneDrive, Outlook, Google Drive and Gmail among its consumer features.
Inside Microsoft 365, Copilot can help write documents, analyze spreadsheet data, build presentations and work with email. What is available depends on the subscription, region and current usage limits.
Who is it best for?
Copilot is most useful for people already working in Microsoft’s ecosystem. It can reduce the friction between asking for help and applying the result in Word, Excel, PowerPoint or Outlook. The free app is also a practical general assistant for writing, research and everyday questions.
It is less suitable when a user expects every Copilot product to behave the same way, needs guaranteed factual accuracy, or wants to use sensitive information without first checking whether the account is personal, business or educational.
Pricing and access
The consumer Copilot app has a free experience. Microsoft 365 Personal includes Copilot and was listed at $9.99 per month in the United States when checked on September 20, 2026. Family was listed at $12.99 per month, while Premium was listed at $19.99 per month. Business and enterprise offers use separate plans and may require eligible Microsoft 365 subscriptions.
Prices vary by country, billing period and promotion, so the official pricing page remains the final reference.
Strengths and limitations
Copilot’s main strength is integration: users can move between chat, files and Microsoft 365 applications instead of copying every result into another tool. It also combines text, files, web information and visual features in one product family.
The main limitation is product complexity. The name Copilot covers consumer, Microsoft 365, business and enterprise experiences with different entitlements. Generated answers can also be incomplete or wrong, so important claims and spreadsheet conclusions still require human review.
Privacy and data use
Microsoft publishes separate privacy guidance for personal Copilot accounts, home Microsoft 365 subscriptions and organizational accounts. Its consumer documentation says conversation activity may be used to improve AI models for eligible users, with controls to opt out. Organizational accounts with Enterprise Data Protection follow different terms.
Before sharing confidential material, confirm which account is active and read the policy that applies to that exact Copilot experience.
In short
Microsoft Copilot is strongest as an AI assistant connected to Microsoft’s productivity ecosystem. It can be useful outside that ecosystem too, but users should distinguish between its different products, plans and data rules.
