Copilot is Microsoft’s answer to the AI moment, a sprawling assistant embedded inside Windows, Edge, Office, Teams, and more. It drafts your emails, summarizes your meetings, builds your slides, and, in its most ambitious form, autonomously takes tasks off your plate entirely. 

It is not the most powerful AI chatbot on the market, but few products are as deeply woven into an existing work ecosystem. Whether you’re evaluating it for your team or just trying to figure out what all the fuss is about, here is everything you need to know about Microsoft Copilot in 2026.

What is Microsoft Copilot?

Microsoft Copilot is an AI-powered assistant integrated throughout the Microsoft ecosystem, including Windows 11, Edge browser, Bing search, and the full suite of Microsoft 365 applications. Rather than operating as a standalone chatbot, Copilot functions as an intelligence layer built directly into the tools millions of people already use for work.

At its core, Copilot processes natural language prompts and produces responses using large language models, primarily OpenAI’s GPT-5 series, supplemented by Anthropic’s Claude models for specialized tasks. Think of it as a capable virtual assistant that happens to know where all your files, emails, and meetings live.

The current version is considerably more than a text box. Copilot can browse the web, analyze uploaded files, generate images, conduct deep research, and — through its newest Cowork feature — carry out multi-step tasks on your behalf inside Microsoft 365 apps.

Who made Copilot?

Copilot is a Microsoft product, though its AI capabilities are largely powered by OpenAI, in which Microsoft has invested billions of dollars. The product traces its origins to GitHub Copilot, a coding assistant that launched in 2021 following Microsoft’s 2018 acquisition of GitHub. Since then, the Copilot brand has expanded to cover nearly every surface of Microsoft’s product lineup.

Microsoft employs more than 200,000 people worldwide and is one of the largest technology companies on earth. Its AI ambitions have been central to the company’s strategy for the past three years, with Copilot serving as the public face of that push.

What does Copilot do?

Copilot handles a wide range of tasks depending on where you access it and which plan you are on. Its core strengths span writing, summarization, data analysis, image generation, and research, but the more distinctive value comes from its integration with Microsoft’s apps.

Core capabilities at a glance

• Chat: Question answering, brainstorming, planning, and general conversation across any topic.
• Write: Emails, reports, summaries, social media posts, and long-form documents with adjustable tone.
• Research: Web search, deep research reports with cited sources, 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 can send emails, schedule meetings, post to Teams, and manage your calendar, with your approval at each step.
• Image generation: Create and edit images via DALL-E integration directly inside Word and PowerPoint.
• Voice: Real-time voice chat through Copilot Voice, available across web, desktop, and mobile.
• 3D modeling: Copilot can turn standard images into 3D models, a specialized tool for digital creators.

One of the more significant 2026 additions is Cowork, Microsoft’s agentic productivity feature. It allows Copilot to carry out multi-step tasks on your behalf, pausing to request your approval before anything sensitive goes out. It uses a set of built-in skills covering Word, Excel, PowerPoint, PDF, email, scheduling, and more, and supports up to 20 custom user-defined skills stored in OneDrive.

Where is Copilot available?

Copilot is accessible across most major platforms, though some features are limited by subscription level. The core chatbot experience is available on the web, desktop (macOS and Windows), and mobile (Android and iOS).

• Web: copilot.microsoft.com, accessible in any modern browser.
• Mobile: iOS and Android apps with voice chat and file upload.
• Desktop: macOS and Windows apps.
• Windows 11: Built-in Copilot key on compatible keyboards; Vision for screen-aware assistance.
• Microsoft Edge: Copilot sidebar integrated directly into the browser.

• Cowork: Available at m365.cloud.microsoft and in the Microsoft 365 Copilot desktop app.

Note: Copilot is no longer accessible inside messaging platforms like WhatsApp. For the full chatbot experience, use Copilot’s dedicated apps or web interface.

How much does Copilot cost?

Copilot’s pricing runs from free to $50 per user per month, with individual and enterprise tiers. One important detail: Copilot Pro cannot be purchased as a standalone product; 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 the total cost. Large organizations may negotiate tailored pricing.

Which AI models power Copilot?

Unlike Claude or ChatGPT, Copilot does not run on proprietary in-house models. Instead, it is 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 used for generating custom images and diagrams.

Which Copilot mode should you use?

Copilot does not offer a model selector the way other chatbots do. Instead, it lets you choose from several modes. Here is a quick guide:

• Quick Response: Best for simple prompts that do not require an internet search.
• Search: Use for questions that need current information from the web.
• Smart: Ideal for complex tasks requiring a quick response, such as 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 a wave of 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 carry out tasks across your Microsoft 365 environment on your behalf — 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

Even free-tier users can now access Copilot in Word, Excel, and Outlook via the Universal Embedded Experience, though with limited capabilities compared to paid subscribers.

Copilot Voice 

A voice interface that can schedule meetings, manage your inbox, deliver summaries, and execute commands through natural speech. Copilot Vision — which lets Copilot see and discuss what is on your screen in real time — is also available during voice sessions. Eight voice options are offered across a wide range of supported languages.

3D modeling

Copilot can now convert photos into 3D models, with results downloadable as GIFs — a curious feature, but one that digital creators may find genuinely useful.

Privacy, data, and security

Microsoft’s data handling is governed by three separate privacy documents: Copilot Privacy Controls, Microsoft’s main privacy policy, and the Microsoft 365 Copilot privacy policy. The key points for most users:

• Training opt-out: Microsoft uses your Copilot conversations for model training by default. You can opt out in settings.
• Conversation history: Retained for 18 months by default. You can delete individual conversations or your entire history.
• Microsoft 365 Copilot: Does not use your prompts, responses, or documents to train its underlying models. Content is accessed only when you explicitly ask Copilot to use it.
• Memory: Copilot can remember details about you across conversations. This can be disabled or reviewed in settings.
• Ads: You can opt out of personalized ads in Copilot and other Microsoft services.
• Enterprise security: Microsoft 365 Copilot plans include enterprise-grade security controls and access to company data only through Microsoft Graph.

Microsoft holds SOC 2 and ISO 27001 certifications. As with any cloud platform, conversations can be subpoenaed in legal proceedings. Handle sensitive professional information accordingly.

Criticisms, limitations, and open questions

No AI product is without gaps, and Copilot has its share of shortcomings.

• Underlying models: Despite the breadth of Copilot’s integration, its chatbot performance in head-to-head testing trails ChatGPT and Gemini on image generation, complex reasoning, and deep research.
• Image generation: Results tend toward generic stock-photo aesthetics. ChatGPT and Gemini produce more detailed and coherent images in direct comparisons.
• Video generation: Copilot does not offer native AI video generation. ChatGPT used to have Sora before it was shut down last month; Gemini has Veo. Copilot’s closest equivalent is AI-assisted slideshow creation in Clipchamp.
• Deep research: Reports are generated faster than competitors but tend to be shorter and cite fewer sources than ChatGPT’s or Gemini’s outputs.
• Ecosystem lock-in: Copilot’s value drops significantly for users who work across platforms. Mixed IT environments involving Google Workspace, Slack, or Notion will see limited contextual benefit.
• The trust gap: According to an analysis from Workativ, “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.”
• Output consistency: User reviews flag variability in output quality consistently across prompts and applications. Complex Excel analysis and technical tasks regularly require manual verification.
• Privacy defaults: Training on user conversations is now opt-out rather than opt-in.

What are Copilot’s competitors?

The AI assistant market has consolidated around a small number of major players, each with distinct strengths.

Product	Made by	Standout strength
ChatGPT	OpenAI	Market leader by usage; strong image generation and versatility; GPT-5 family
Claude	Anthropic	Long-context document handling, coding, and constitutional AI safety focus
Gemini	Google	Deeply embedded in Google Workspace and Android; strong multimodal performance
Perplexity AI	Perplexity	Always cites sources; best for current-events research
Grok	xAI	Real-time social intelligence; bundled with X Premium
Meta AI	Meta	Open-weight model across Facebook, Instagram, WhatsApp; popular for self-hosting
DeepSeek	DeepSeek (China)	Strong reasoning at low cost; raises data privacy concerns

For coding tasks specifically, GitHub Copilot — a separate Microsoft product — competes directly with Cursor, Claude Code, and other agentic coding tools. GitHub Copilot pricing varies by plan and is distinct from the Microsoft 365 Copilot tiers above.

Is Copilot worth the money?

The answer depends entirely on how you work.

Worth it if:

• Your company is already covering Microsoft 365 licenses; adding Copilot is a no-brainer.
• You basically live in Microsoft apps. If your daily routine means hopping between Word, Excel, Outlook, and Teams from 9 to 5, Copilot saves you real minutes every hour.
• Meeting-heavy professionals. People who sit through back-to-back meetings all week will find the automatic summarization and action-item tracking genuinely useful.

Not worth it if:

• You’re budget-conscious freelancers and solopreneurs.
• Your team uses Google Workspace, Slack, Notion, or Asana alongside Microsoft tools; Copilot loses much of its magic. 
• You do creative or deeply technical work. Writers, designers, and developers often find standalone tools like ChatGPT or Claude more flexible for their actual needs.
• You don’t want to go all-in on one ecosystem. Some folks prefer to keep their options open rather than deepen their dependence on Microsoft. 

How to get started with Copilot

• Sign In: Visit m365.cloud.microsoft and sign in with your Microsoft, Apple, or Google account.
• Choose a mode: Use the drop-down menu to select from options such as “Think Deeper” for complex science/math, or “Quick Response” for simple queries.
