Copilot is Microsoft's AI assistant, embedded across Windows, Edge, Office, Teams, and more. It drafts emails, summarizes meetings, builds presentations, and in its most ambitious form, autonomously handles tasks on your behalf.
It's not the most powerful AI chatbot available, but few products integrate this deeply into an existing work ecosystem. Whether you're evaluating it for your team or trying to understand the hype, here's what you need to know about Microsoft Copilot in 2026.
What is Microsoft Copilot?
Microsoft Copilot is an AI assistant woven throughout the Microsoft ecosystem: Windows 11, Edge, Bing, and the full Microsoft 365 suite. Rather than functioning as a standalone chatbot, Copilot operates as an intelligence layer built into tools millions already use daily.
It processes natural language prompts and generates responses using large language models, primarily OpenAI's GPT-5 series, with Anthropic's Claude models handling specialized tasks. Think of it as a capable virtual assistant that knows where your files, emails, and meetings live.
The current version goes well beyond a text box. Copilot browses the web, analyzes uploaded files, generates images, conducts research, and through its newest Cowork feature, executes multi-step tasks inside Microsoft 365 apps.
Who made Copilot?
Copilot is a Microsoft product, though its AI capabilities come largely from OpenAI, in which Microsoft has invested billions. The product originated with GitHub Copilot, a coding assistant launched in 2021 following Microsoft's 2018 GitHub acquisition. The Copilot brand has since expanded across nearly every Microsoft product.
Microsoft employs over 200,000 people worldwide and ranks among the largest technology companies globally. AI has been central to the company's strategy for three years, with Copilot as the public face of that effort.
What does Copilot do?
Copilot handles a wide range of tasks depending on where you access it and your subscription tier. Core strengths include writing, summarization, data analysis, image generation, and research, but the real value lies in its Microsoft app integration.
Core capabilities at a glance
- Chat: Question answering, brainstorming, planning, and general conversation.
- Write: Emails, reports, summaries, social posts, and long-form documents with adjustable tone.
- Research: Web search, deep research reports with citations, and document analysis.
- Analyze: Upload spreadsheets, PDFs, images, and charts for interpretation or data extraction.
- Present: Generate PowerPoint decks from prompts or Word documents with one command.
- Automate: Through Cowork, Copilot sends emails, schedules meetings, posts to Teams, and manages your calendar, with approval at each step.

How much does Copilot cost?
Copilot pricing ranges from free to $50 per user per month, with individual and enterprise tiers. One important detail: Copilot Pro cannot be purchased standalone; it requires an active Microsoft 365 Personal or Family subscription.
| Plan | Price | Best for |
|---|---|---|
| Copilot (Free) | $0/month | Basic web chat in Edge, Bing, and Windows 11; limited image generation; 5 GB OneDrive storage |
| Microsoft 365 Personal | $9.99/month | Copilot integrated into Microsoft 365 apps (web/mobile), higher usage limits |
| Microsoft 365 Family | $12.99/month | Same as Personal, up to 6 users; Copilot features for account holder only |
| Microsoft 365 Premium | $19.99/month | Highest image generation limits, Copilot agents like Researcher, priority access |
| Microsoft 365 Copilot Business | $18/user/month (annual) | SMBs under 300 seats; Copilot in all Microsoft 365 apps with admin controls |
| Microsoft 365 Copilot (Enterprise) | $30/user/month (annual) | Full Microsoft 365 integration, enterprise security, Microsoft Graph data access |
| Copilot for Sales/Service | $50/user/month | Bundles Enterprise Copilot with Dynamics 365 insights for sales and service teams |
Enterprise plans require a qualifying Microsoft 365 E3, E5, Business Standard, or Business Premium license, meaning the $30 add-on reflects only part of total cost. Large organizations may negotiate custom pricing.
Which AI models power Copilot?
Unlike Claude or ChatGPT, Copilot doesn't run on proprietary in-house models. It's powered primarily by OpenAI's GPT-5 series, supplemented by Anthropic's Claude models for specialized use cases in Microsoft 365.
- GPT-5 series: Includes GPT-5.4 Thinking for advanced reasoning and GPT-5.3 Instant for quick responses.
- Anthropic Claude: Claude Opus 4.5 and Claude Sonnet 4.5 are available for specialized tasks in 365 Copilot and Copilot Studio.
- MAI-Image-2: Microsoft's in-house model for generating custom images and diagrams.
Which Copilot mode should you use?
Copilot doesn't offer a model selector like other chatbots. Instead, it provides several modes. Here's a quick guide:
- Quick Response: Best for simple prompts that don't require internet search.
- Search: Use for questions needing current information from the web.
- Smart: Ideal for complex tasks requiring quick responses, like image recognition, file processing, and basic math.
- Smart Plus: Use this in place of Smart when available; it runs on a more capable model.
- Study and Learn: Best when you want to understand a topic rather than receive a direct answer.
- Think Deeper: Reserve for hard reasoning problems, complex math, science, or programming where you want Copilot to spend extra time.
- Deep Research: Accessed via a separate menu; generates comprehensive reports with sources on any topic.
What's new in Copilot in 2026?
The past twelve months brought updates that push Copilot further into autonomous territory. Here are the most significant changes.
Cowork (agentic task execution)
Cowork is the headline feature of 2026. It allows Copilot to execute tasks across your Microsoft 365 environment — sending emails, scheduling meetings, creating Word documents, posting in Teams, and managing your calendar. Each action requires your approval before Copilot proceeds. It supports 13 built-in skills and up to 20 custom skills, and is available at m365.cloud.microsoft. The feature is currently in preview through Microsoft's Frontier program.
Agent Mode
Available in Microsoft 365 apps on paid plans, Agent Mode enables Copilot to work iteratively on complex deliverables, conducting multi-step research, applying feedback, and refining content with minimal manual prompting between steps.
Work IQ
Work IQ is an intelligence layer that enriches Copilot's responses with contextual awareness of your organizational data, pulling from emails, documents, calendar events, and line-of-business applications through Microsoft Graph. The result is a Copilot that understands your current projects and relationships, not just your prompt.
Model choice in Microsoft 365 Copilot
Microsoft 365 Copilot now offers model choice in Copilot Studio, allowing users to direct specific tasks to Claude Sonnet 4.5 or Claude Opus 4.5 from Anthropic. The Researcher agent can leverage deep reasoning from either OpenAI's latest model or Claude Opus 4.5 for complex analytical work.
Universal Embedded Experience
Microsoft now extends Copilot access to free-tier users within Word, Excel, and Outlook through its Universal Embedded Experience. While this marks a significant expansion of availability, free users receive a scaled-back feature set compared to paying subscribers.
Copilot Voice
The voice interface handles meeting scheduling, inbox management, content summarization, and command execution through conversational speech. During voice sessions, users can activate Copilot Vision, enabling the AI to analyze and discuss on-screen content in real time. Microsoft offers eight distinct voice profiles supporting multiple languages.
3D Modeling
A new capability converts photographs into three-dimensional models, with output available as downloadable GIFs. While the practical applications may seem niche, digital content creators could find legitimate use cases for this functionality.
Privacy, Data, and Security
Microsoft's data practices are outlined across three documents: Copilot Privacy Controls, the company's general privacy policy, and the Microsoft 365 Copilot-specific privacy policy. Essential considerations include:
- Model training: By default, Microsoft uses Copilot conversations to train its models. Users must actively opt out through settings.
- Conversation retention: Chat history is stored for 18 months unless users manually delete individual exchanges or clear their entire history.
- Microsoft 365 Copilot data usage: Enterprise versions do not train models on user prompts, responses, or documents. The system accesses content only when explicitly instructed.
- Contextual memory: Copilot retains information across sessions to personalize responses. This feature can be disabled or audited in settings.
- Advertising: Personalized ad targeting can be disabled across Copilot and other Microsoft properties.
- Enterprise protections: Business-tier plans include enterprise security frameworks and restrict data access through Microsoft Graph.
Microsoft maintains SOC 2 and ISO 27001 certifications. Like all cloud services, conversation data may be subject to legal discovery requests. Users should exercise appropriate caution with confidential information.
Criticisms, Limitations, and Open Questions
Copilot faces several documented weaknesses that affect its competitive position.
- Core model performance: Comparative testing shows Copilot trailing ChatGPT and Gemini in image generation, advanced reasoning, and research depth.
- Image quality: Generated visuals skew toward generic, stock-photography aesthetics. Direct comparisons favor ChatGPT and Gemini for detail and coherence.
- Video generation absence: Copilot lacks native video creation capabilities. ChatGPT previously offered Sora before its shutdown; Gemini provides Veo. Copilot's closest analog is AI-enhanced slideshow assembly in Clipchamp.
- Research capabilities: While faster than competitors, Copilot's research reports are typically shorter and cite fewer sources than equivalent outputs from ChatGPT or Gemini.
- Platform dependency: Value proposition deteriorates sharply outside the Microsoft ecosystem. Organizations using Google Workspace, Slack, or Notion alongside Microsoft tools see diminished contextual integration.
- Reliability concerns: Analysis from Workativ notes that "users still don't trust it for complex, technical, or organization-specific work. Advanced Excel analysis, multi-sheet logic, and nuanced calculations often require manual verification, which limits Copilot's use in scenarios where accuracy and execution matter."
- Inconsistent results: User feedback consistently highlights variable output quality across prompts and applications. Technical tasks and sophisticated Excel operations frequently demand human verification.
- Privacy configuration: Training on user data is opt-out rather than opt-in, placing the burden on users to protect their information.
What Are Copilot's Competitors?
The AI assistant landscape has narrowed to a handful of dominant platforms, each with differentiated capabilities.
| Product | Developer | Key Differentiator |
|---|---|---|
| ChatGPT | OpenAI | Largest user base; superior image generation and flexibility; GPT-5 architecture |
| Claude | Anthropic | Extended context windows for documents; coding proficiency; constitutional AI framework |
