If you've seen the little "Try Copilot" button pop up in Word or Outlook and wondered whether it's worth clicking, you're not alone. Microsoft has been quietly upgrading the AI model (the brain that writes the text and looks at your data) that sits behind Microsoft 365 Copilot. The pitch is simple: let the AI handle the boring first draft so you can spend your time on the thinking part.
But what does that actually look like day-to-day? And is it worth the extra cost on top of your Microsoft 365 subscription? Let's walk through it honestly — no hype, just what it is, where it shows up, and who gets the most out of it.
Honest note before we start: I can't promise you the exact menu name or button label for every step on every version of Word, Excel, Outlook, and PowerPoint, because Microsoft moves these around. So instead of fake-precise steps, this guide tells you where Copilot shows up, what it can do, and how to find it on your version. If you want exact clicks, the official Microsoft support pages are the safest source.
What the "new AI model" actually means
Microsoft doesn't always publish the technical details, but the gist is this: Copilot runs on top of large language models (LLMs — think of them as the same family of technology that powers ChatGPT). The "new model" generally refers to a newer generation that's better at:
- Following longer, more specific instructions
- Reading and writing across longer documents
- Working with your own files (emails, documents, spreadsheets) rather than just general knowledge
- Producing more natural-sounding drafts
In plain English: it gets closer to "give it a rough idea and it does the first pass well" than older versions did.
Where Copilot shows up across Microsoft 365
You'll find Copilot as a button, a sidebar, or a chat box in the main Microsoft 365 apps. The exact look depends on your version (desktop app, web app, or Mac) and how recently it was updated.
Word
In Word, Copilot can:
- Draft a document from a short prompt (e.g. "Write a project update based on these notes")
- Rewrite or tidy up selected text ("Make this more professional" / "Shorten this paragraph")
- Summarize a long document into key points
You'll usually see Copilot as a sidebar on the right, or as options that appear when you highlight text.
Excel
In Excel, Copilot works on your spreadsheet data:
- Explain what's in a sheet ("What are the top 5 customers by revenue?")
- Create formulas in plain English ("Add a column that flags orders over $500")
- Suggest charts based on your data
- Summarize trends without you building pivot tables (pivot tables are Excel's built-in tool for slicing and summarizing data)
You'll find Copilot prompts in the home ribbon, often near the top-right of the sheet.
Outlook
In Outlook (newer versions especially), Copilot helps with email:
- Summarize a long email thread so you can catch up quickly
- Draft replies in a tone you choose (friendly, formal, short)
- Coach you on tone before you send ("Is this email too blunt?")
Look for the Copilot icon near the reply box, or in the email's top toolbar.
PowerPoint
In PowerPoint, Copilot can:
- Build a first draft of a deck from a Word document or outline
- Add speaker notes to existing slides
- Restyle a messy deck into a cleaner layout
- Generate images to support your slides
You'll usually find a Copilot option in the Home ribbon, or by right-clicking on the slide background.
What you need before you start
Before you click anything, make sure you have:
- A Microsoft 365 subscription (the personal or family plan, or a business plan via your employer)
- A Copilot license — this is a paid add-on on top of Microsoft 365. It's not included in the standard subscription. Pricing varies by region and plan; check Microsoft's site for current pricing.
- The latest version of Word, Excel, Outlook, and PowerPoint — Copilot features roll out gradually, so older versions may not show them
- Your data in OneDrive or SharePoint if you want Copilot to read your files (instead of just working on a blank document)
If your workplace manages your Microsoft 365 account, your IT team controls whether Copilot is available to you — it may be turned off.
Five realistic ways to use it
Here are five everyday tasks where Copilot genuinely saves time, based on what users commonly report. Treat these as starting points — your real prompts will depend on your actual work.
1. Drafting an email from a few rough points
Open Outlook, click the Copilot option when composing, and type something like:
💬 "Draft a friendly reply confirming the meeting on Thursday at 2pm and asking them to bring the latest figures."
Copilot produces a first draft. You tweak the wording and send.
2. Summarizing a long email chain
In a long thread, look for a Copilot "Summarize" option. It'll give you a short paragraph covering the main points, decisions, and open questions — useful when you're catching up after a day off.
3. Turning notes into a slide deck
In PowerPoint, start a new presentation and use the Copilot "Create from draft" or "Create from outline" option. Paste in bullet points or a Word doc, and ask for:
💬 "Turn these notes into a 6-slide deck with a title slide, three content slides, and a closing summary slide."
You'll get a starting deck to refine, not a finished presentation.
4. Explaining a spreadsheet
In Excel, ask Copilot a plain-English question about your data:
💬 "Which product category had the highest sales last quarter, and by how much?"
Copilot will answer in text and often suggest a chart to visualise it.
5. Rewriting your own writing
In Word, highlight a paragraph and look for a Copilot "Rewrite" option. You can ask it to:
💬 "Make this clearer and cut it by a third."
It's a quick way to tighten up your own draft without starting over.
Common mistakes to avoid
- Mistake: Expecting it to read your whole computer. Copilot can only see files you give it access to (usually through OneDrive, SharePoint, or the open document). If a file isn't shared with it, Copilot can't read it. Fix: Make sure the documents you want Copilot to use are saved in OneDrive or SharePoint, not just on your local desktop.
- Mistake: Trusting the first draft without checking. Copilot can confidently make things up — wrong numbers, invented client names, fake meeting times. Fix: Always read the output before sending or sharing, especially anything with specific facts, dates, or figures.
- Mistake: Using vague prompts. "Help me with this email" gives you generic results. Fix: Be specific — say what the email is about, what tone you want, and what outcome you need.
- Mistake: Assuming it's free. Copilot is an extra paid license on top of Microsoft 365. Fix: Check your subscription before you spend an hour setting it up, only to find it's not included.
- Mistake: Letting it handle sensitive data without thinking. If you work in healthcare, law, or finance, anything you paste into Copilot may be processed by Microsoft's AI systems. Fix: Check your workplace's AI and data-handling policy before using Copilot on confidential material.
Wrap-up
The new AI model behind Microsoft 365 Copilot is genuinely useful for one thing: cutting the time you spend on first drafts and routine cleanup. It's not magic, it's not free, and it's not a replacement for thinking — but for the right person, doing the right kind of work, it can give you back a meaningful chunk of your week.
Start small: pick one task you do often (an email, a meeting summary, a slide deck) and try Copilot on it once. If it saves you ten minutes, great. If it doesn't, you haven't lost much.
