Microsoft Copilot is an AI assistant built into Windows, Microsoft 365, and the Edge browser. It can write emails, summarise documents, create presentations, answer questions, and help you get work done faster, all from a chat box that sits beside the program you are already using. If you have used ChatGPT or another AI chat tool, Copilot will feel familiar. The difference is that Copilot works inside the Microsoft apps many people already use every day, and it can use your own files, emails, and meetings as context.
This beginner’s guide explains Microsoft Copilot in plain English. You will learn what Copilot is, where you can find it, what it can and cannot do, how much it costs, and whether it is worth using. You do not need to be a Microsoft expert to follow along, and by the end you will know how to try Copilot for free and how to use it safely at work.
What Is Microsoft Copilot?
Microsoft Copilot is a family of AI assistants made by Microsoft, all built on the same idea: you describe what you want in plain words, and the AI helps you do it. The name comes from the idea of a co-pilot in an aeroplane. You are still in charge, and the AI sits beside you, helping with the routine work so you can focus on the decisions that matter. It can draft text, find information, summarise long documents, and carry out small tasks, but it does not replace your judgement.
Copilot is powered by large AI models, including models from OpenAI, the company behind ChatGPT, combined with Microsoft’s own technology. When you ask Copilot a question, it uses those models to work out a helpful answer, and when you are using it inside Microsoft 365, it can also look at your documents, emails, and calendar to give answers that fit your work. For example, it can summarise a meeting you missed, draft a reply to an email thread, or turn a Word document into a short presentation.
There are several versions of Copilot, and the names can be confusing. The free version is built into Windows 11 and the Edge browser, and anyone with a Microsoft account can try it. Microsoft 365 Copilot is the paid version for work, built into Word, Excel, PowerPoint, Outlook, and Teams. There is also Copilot in the Microsoft 365 app on your phone, and a version for developers inside GitHub, called GitHub Copilot, which helps programmers write code. This guide focuses on the versions most people will meet: Copilot in Windows and Copilot in Microsoft 365.
Where Can You Find Copilot?
In Windows 11, Copilot is the small icon on the taskbar, and you can also open it with the Copilot key on newer keyboards. Click it, and a chat panel opens on the side of your screen. You can ask it questions, ask it to change a setting, or ask it to help with a file you have open. It works like a chat assistant that is always available, without opening a separate website.
In Microsoft 365 apps, Copilot appears inside the app itself. In Word, you will see a Copilot button that can draft text, rewrite a paragraph, or summarise a document. In Excel, it can explain a formula, find patterns in your data, or create a chart from a table. In PowerPoint, it can turn a document into slides, or suggest a design for a slide you have written. In Outlook, it can summarise a long email thread and draft a reply. In Teams, it can summarise a meeting and list the decisions that were made.
Copilot is also available on the web at copilot.microsoft.com and in the Copilot app for iPhone and Android. The free version works with a Microsoft account, and you can use it for general questions, writing, and image generation. The paid work version needs a Microsoft 365 subscription and a Copilot licence, which your employer usually provides if your workplace uses it.
What Can Copilot Do?
Copilot is most useful for writing and summarising. It can draft an email in a polite tone, rewrite a message to be shorter or more formal, or turn bullet points into a proper paragraph. It can summarise a long report into five key points, or a meeting into a list of actions. It can also help you start a document when you are facing a blank page, by suggesting an outline or a first draft you can edit.
In Excel, Copilot can help people who are not confident with spreadsheets. You can ask it in plain English, such as show me the total sales by month, and it will suggest a formula or a chart. In PowerPoint, it can create a first draft of a presentation from a Word document, saving hours of copying and pasting. In Outlook, it can help you catch up on a long email thread in seconds, and draft a reply that covers the main points.
Copilot can also create images from a text description, answer general knowledge questions, and help with everyday tasks such as planning a trip, writing a shopping list, or explaining a difficult idea in simple words. Like other generative AI tools, it creates new text and images from your instructions, rather than just searching for existing ones. The quality of the result depends on how clearly you describe what you want, which is why learning to write good prompts helps so much with Copilot.
What Copilot Cannot Do
Copilot is not perfect, and it is important to know its limits. It can make mistakes, invent facts, and give answers that sound confident but are wrong. Always check important facts, numbers, and names before you use a Copilot answer at work or share it with anyone else. It also cannot do things that need real human judgement, such as deciding what is fair, understanding office politics, or knowing what a customer really needs when they have not said it clearly.
Copilot cannot access files or information it has not been given permission to see, and it cannot replace a person for sensitive conversations. It should not be used to make decisions about hiring, health, or money without a person checking the result. It also cannot keep a secret perfectly: anything you type into a public AI tool could be stored or used to improve the service, so you should not put passwords, private customer data, or confidential business information into Copilot unless your workplace has a business version with clear privacy rules.
How Much Does Microsoft Copilot Cost?
The basic version of Copilot in Windows and on the web is free with a Microsoft account. You can ask questions, get help with writing, and create images without paying. There are limits on how many messages you can send in a row, and some advanced features are only available in the paid version, but for trying Copilot out, the free version is enough.
Microsoft 365 Copilot, the work version built into Word, Excel, PowerPoint, Outlook, and Teams, is a paid add-on. In 2026 it typically costs around 30 dollars per user per month on top of a Microsoft 365 subscription, although prices and plans change, and many employers pay for it for their staff. There is also a Copilot Pro version for individuals, which costs around 20 dollars per month and adds Copilot to the Microsoft 365 apps you already use at home. Before you pay, try the free version first, and check whether your workplace already provides the work version, because many people pay for something they already have access to through work or school.
How to Use Copilot Well
Getting good results from Copilot is mostly about writing clear prompts. Tell it who you are writing for, how long the answer should be, and what tone you want. Give it the details it needs, such as the key points to include, and tell it what to leave out. If the first answer is not quite right, ask it to try again with a small change, such as make it shorter, or use simpler words. Copilot works best as a first draft, not a final answer: use it to start, then edit the result in your own voice.
- Be specific: say what you want, who it is for, and how long it should be.
- Give context: paste in the document, email, or notes Copilot should use.
- Ask for a format: a list, a table, a short email, or step-by-step instructions.
- Check the answer: read it, check facts, and fix anything that sounds wrong.
- Keep private data out: do not paste passwords or confidential information into a public AI tool.
It also helps to learn the Copilot features inside the apps you use most. In Word, try asking Copilot to summarise a long document before you read it. In Outlook, try asking it to draft a reply to a difficult email, then edit the draft before you send it. In Excel, try asking it to explain a formula you do not understand. Small experiments like these are the fastest way to learn what Copilot is good at, and where you still need to do the work yourself. If you need a refresher on the basics of AI chat tools, read our guide to what ChatGPT is and how it works, because many of the same ideas apply to Copilot.
Should You Use Microsoft Copilot?
Copilot is worth trying if you already use Windows and Microsoft 365, because it is built in and the free version costs nothing to test. It can save time on writing, summarising, and routine office tasks, especially if you deal with a lot of emails and documents. It is less useful if you rarely use Microsoft apps, or if you need an AI tool for a very specialised job, such as coding or image design, where a dedicated tool may do a better job.
For workplaces, Copilot can help a whole team work faster, but it works best when everyone is trained to use it well and when there are clear rules about what data can be shared with it. For students, it can help with studying and planning, but it should not be used to write essays or assignments for you, because that can break school rules and stop you learning. Like any tool, Copilot is most useful when you understand what it does well, what it does badly, and when to trust your own judgement instead.
Conclusion
Microsoft Copilot is an AI assistant built into Windows and Microsoft 365 that helps you write, summarise, plan, and create, using plain English instructions. The free version is a good place to start, and the paid work version adds Copilot to Word, Excel, PowerPoint, Outlook, and Teams. It can save you a lot of time, but it can also make mistakes, so always check its answers and keep private information out of your prompts. Try it for a few everyday tasks, learn what it does well, and use it as a helper, not a replacement for your own thinking.
