Microsoft Copilot is Microsoft's unified AI assistant, rolling out across Windows 11, Microsoft 365, Edge browser, Teams, and mobile apps since late 2023. Built on OpenAI's GPT-4 models through Microsoft's multi-billion dollar partnership with OpenAI, Copilot represents Microsoft's strategic bet that AI assistance should be embedded into every product, not just a standalone tool users opt into separately.
The free version of Copilot (at copilot.microsoft.com or the Windows 11 taskbar) provides GPT-4-powered conversational AI with real-time web search enabled by default — a significant advantage over ChatGPT's free tier, which uses a less capable model. This makes Copilot one of the most capable free AI assistants available, with current web knowledge built in rather than requiring a paid tier. The free version also includes image generation via DALL-E through Bing Image Creator with daily boost allocations.
Copilot Pro at $20/month unlocks priority access to the latest GPT-4 models and activates Copilot features within Microsoft 365 desktop apps for personal subscribers. In Word, this means AI drafting and rewriting. In Excel, it means natural language data analysis and formula generation. In PowerPoint, it creates presentation slides from prompts or existing documents. In Outlook, it summarizes email threads and drafts replies matching your communication style.
For enterprises, Microsoft 365 Copilot at $30/user/month adds business-grade security, compliance controls, and a unified enterprise AI experience across all Microsoft 365 apps with organizational data access. This tier is designed for companies that need Copilot to work with internal documents, SharePoint content, and Teams meeting recordings while maintaining data sovereignty and audit trails.
Key Features
Real-Time Web Search
Copilot searches the web by default, providing up-to-date answers with cited sources — no knowledge cutoff. Ask about current events, stock prices, weather, or recent news and get current results.
Microsoft 365 Integration
Draft Word documents, analyze Excel data, create PowerPoint presentations, summarize email threads in Outlook, and generate meeting notes from Teams calls — all via natural language prompts.
AI Image Generation

Enterprise Security (Business Tier)
Microsoft 365 Copilot for business enforces your organization's data boundaries. Copilot only accesses content your employees are permitted to see, with full audit trails and compliance controls.
Mobile App
Available on iOS and Android with voice input support. Ask questions, generate images, and access Office features on the go with the same GPT-4-powered experience as the desktop version.

Is Microsoft Copilot free?
Yes — the base Microsoft Copilot is free.

What is the difference between Microsoft Copilot and ChatGPT?
Both use OpenAI's models, but they're distinct products. Copilot is Microsoft's product integrated throughout Windows and Microsoft 365, with real-time web search included in the free tier. ChatGPT is OpenAI's standalone product with a broader plugin ecosystem, more advanced reasoning in the Plus tier, and code interpreter for data analysis. Copilot is the better choice if you're already in the Microsoft ecosystem; ChatGPT Plus is better for complex coding, analysis, and reasoning tasks outside of Office productivity.
What can Microsoft Copilot do in Word and Excel?
In Word, Copilot can draft documents from text prompts, rewrite and summarize selected passages, improve clarity and tone, generate tables, and transform bullet points into prose. In Excel, it analyzes data in plain English ("show me the top 5 products by revenue last quarter"), generates formulas while explaining what they do, creates PivotTables from natural language, highlights anomalies, and charts selected data. These features require Copilot Pro for personal Microsoft 365 or Microsoft 365 Copilot for business accounts.
Does Microsoft Copilot have image generation?
Yes. Copilot includes image generation powered by DALL-E via Bing Image Creator. You can generate images directly in the chat interface by describing what you want. Free users get a limited number of "boosted" fast generations per day — after daily boosts are used, generation slows rather than stops. Copilot Pro adds 100 boosted image generations per day. You can also access image generation directly at bing.com/images/create.
Is Microsoft Copilot available on mobile?
Yes. Microsoft Copilot is available as a dedicated app on iOS and Android, providing conversational AI, web search, and image generation on mobile. The app supports voice input so you can speak your prompts. Microsoft 365 mobile apps (Word, Excel, Teams, Outlook) also surface Copilot features for subscribers with active Copilot Pro or Microsoft 365 Copilot licenses. The mobile experience mirrors the web version with the same GPT-4 capabilities.
