Microsoft Copilot is Microsoft’s free AI assistant, and if you use Windows, Edge, Word or Excel, you probably already have access to it without paying anything. Microsoft Copilot can answer questions, write drafts, summarise long documents, explain difficult topics and help you finish everyday work faster. In this
guide, we explain what Microsoft Copilot is, how to use it for free, where it works best, and how it compares with ChatGPT and Google Gemini. Whether you are a student writing assignments, a freelancer managing clients, or an office worker buried in emails, Microsoft Copilot is designed to sit inside the tools you already use, so you do not have to learn a completely new app to benefit from AI.
What Is Microsoft Copilot?
Microsoft Copilot is an AI-powered assistant developed by Microsoft and built on advanced language models from OpenAI. It works like a smart chatbot: you type a question or instruction, and it responds with an answer, a draft, a summary or a plan. The difference from a normal chatbot is that Microsoft Copilot is connected to Microsoft’s products. It can work inside Windows 11, the Edge browser, Bing search, Word, Excel, PowerPoint, Outlook and Teams. You can ask Microsoft Copilot to explain a topic in simple words, write an email, turn rough notes into a proper document, or summarise a long web page. It also searches the web, so its answers can include current information and sources, something that older, offline chatbots could not do. Microsoft first launched Copilot as an assistant for Windows and Microsoft 365, and it has since become the company’s main AI brand. If you have seen a colourful swirl icon on your Windows taskbar or in Edge, that is Microsoft Copilot waiting to help.
How to Use Microsoft Copilot for Free
The good news is that the basic version of Microsoft Copilot is completely free. Here is how to start: On Windows 11, press the Copilot key on your keyboard, or click the Copilot icon on the taskbar. You can also open it from the Start menu. On any device, go to copilot.microsoft.com in your browser and sign in with a free Microsoft account. In the Edge browser, click the Copilot icon in the sidebar to chat while you browse. On your phone, download the free Microsoft Copilot app for Android or iPhone. The free version gives you chat, web search, image generation and document help. There is also a paid plan called Copilot Pro, which adds faster responses, priority access to newer models, and Copilot inside Word, Excel and PowerPoint on personal accounts. But for most students and everyday users, the free version of Microsoft Copilot is more than enough to start with. If you are new to AI tools in general, our guide to free AI tools for students explains how to combine several free tools without spending anything.
Microsoft Copilot in Word, Excel, PowerPoint and Outlook
The real strength of Microsoft Copilot shows up inside Microsoft 365 apps: Word: Ask Microsoft Copilot to draft a letter, rewrite a paragraph in a formal tone, or summarise a long report into key points. Excel: Describe what you want in plain words, for example, highlight the top 5 sales, and Copilot can suggest formulas, charts and summaries. PowerPoint: Give Copilot an outline or a document, and it can build a first draft of your slides with headings and talking points. Outlook: Copilot can summarise long email threads, draft replies, and help you prioritise your inbox. Teams: During or after meetings, Copilot can summarise discussions and list action items. Note that the full in-app Copilot features in Word, Excel and PowerPoint require a Copilot Pro or Microsoft 365 Copilot licence. The free chat version still helps you prepare content that you can paste into these apps yourself, which is exactly what most students and small teams do.
Microsoft Copilot for Students
Students get some of the biggest benefits from Microsoft Copilot: Understanding difficult topics: Ask Copilot to explain physics, chemistry or economics in simple words, with examples. If one explanation does not click, ask for another one. Assignment planning: Turn a question into an outline, then write each section in your own words. Revision notes: Paste your class notes and ask Copilot to turn them into short summaries, flashcards or practice questions. Research help: Copilot searches the web and shows sources, so you can verify facts instead of blindly trusting one answer. Presentations: Draft slide content and speaker notes in minutes, then design the slides yourself. One important rule: use Microsoft Copilot as a tutor, not as a shortcut. Teachers can usually tell when work is copied from AI, and you learn nothing that way. Ask Copilot to explain, quiz you, and check your own drafts — that is how it genuinely improves your grades. Our guide on using AI for exam preparation without cheating covers this in more detail.
Microsoft Copilot for Work and Business
For professionals, Microsoft Copilot saves time on repetitive tasks. It can draft meeting agendas, write follow-up emails, summarise reports, and turn messy notes into clean documents. Small business owners can use it to write product descriptions, social media captions, customer replies and simple business plans. Because Microsoft Copilot works inside tools businesses already pay for, teams do not need to adopt yet another platform. Documents stay inside the Microsoft ecosystem, which also makes it easier for companies that care about privacy and data control. Freelancers can combine Microsoft Copilot with other tools — for example, drafting a proposal in Copilot, designing visuals in Canva, and organising delivery in Notion. The key is to let AI handle the first draft while you keep control of the final quality.
Microsoft Copilot vs ChatGPT and Gemini
How does Microsoft Copilot compare with its two biggest rivals? ChatGPT, covered in our guide to the future of ChatGPT, is the most flexible general chatbot, with a huge ecosystem of features. Google Gemini, explained in our Google Gemini guide, is deeply connected to Google Search, Gmail and Google Docs. Microsoft Copilot sits between them: it is less famous than ChatGPT, but its advantage is integration. If your work already lives in Windows, Outlook and Office, Copilot is right there where you need it, with no extra tabs or subscriptions. For web research with sources, Microsoft Copilot and Perplexity AI both cite their sources well — Perplexity is still the stronger pure research tool, while Copilot is the stronger everyday work assistant.
Limitations of Microsoft Copilot
Microsoft Copilot is powerful, but it is not perfect: It can make mistakes. Like all AI chatbots, Copilot sometimes gives confident but wrong answers. Always verify important facts, prices and dates. Free version limits. Heavy users may hit daily limits, and the newest models are reserved for paying users. In-app features cost extra. Full Copilot inside Word, Excel and PowerPoint needs a paid plan. Privacy awareness. Avoid pasting passwords, private client data or sensitive personal information into any AI chatbot. It cannot replace judgement. Copilot drafts, but you decide. Review everything before sending or submitting.
Is Microsoft Copilot Worth Using?
Yes — especially because the free version costs nothing to try. If you already use Windows or Microsoft 365, Microsoft Copilot is the easiest AI assistant to start with: no new account to learn, no new app to master, and real help with writing, studying and office work from day one. Start with the free chat at copilot.microsoft.com, try it for one week on real tasks — summaries, drafts, explanations — and judge it by the time it saves you. Then, if you want the deeper Office integration, consider Copilot Pro. For most readers of this blog, the free Microsoft Copilot will already be a genuine productivity upgrade.
