I've evaluated Microsoft Copilot for a handful of enterprise clients over the past year. And every single time, the first question isn't "how does it work?" It's "wait, which Copilot are we talking about?"
Microsoft's branding here is a genuine mess. There are at least four distinct Copilot products, they're all called Copilot, and they do different things at different price points. Before you can learn how to use it, you need to know which "it" you're actually dealing with.
Let me fix that.
1. What Microsoft Copilot Actually Is (The Name Confusion)
Microsoft slapped the "Copilot" name on several products that share little more than a brand. Here's the breakdown:
Copilot Free -- The consumer-facing AI chatbot available at copilot.microsoft.com and built into Windows 11. Powered by GPT-4o (via Microsoft's OpenAI partnership). Free with any Microsoft account. This is what most people mean when they say "Microsoft Copilot."
Copilot Pro -- The $20/month upgrade to Copilot Free. Gives you priority access to GPT-4o, image generation via Designer (DALL-E), and Copilot integration in Microsoft 365 apps if you have a personal Microsoft 365 subscription.
Microsoft 365 Copilot -- The enterprise product. $30/user/month on top of an existing Microsoft 365 E3 or E5 license. This is Copilot integrated into Word, Excel, Outlook, PowerPoint, and Teams at scale, with your organization's data. This is what your IT department talks about in board presentations.
Copilot in Windows -- Copilot built into the Windows 11 taskbar. Technically separate from the web version. Can control some Windows settings, summarize open documents, answer questions. Uses the same underlying model.
When someone says "Copilot isn't that impressive," they're usually talking about Copilot Free. When someone says "Copilot changed how our team works," they're almost certainly talking about Microsoft 365 Copilot with a full M365 E3 deployment.
These are not the same product.
2. Copilot Free vs Copilot Pro ($20/mo) -- What You Actually Get
For most personal users, the decision is between Free and Pro.
Copilot Free gives you:
- GPT-4o access (slower, throttled during peak hours)
- Web search integration
- Image generation (limited -- 15 boosts/day via Designer)
- Access via copilot.microsoft.com, Windows 11, the mobile app, and Edge sidebar
Copilot Pro ($20/mo) adds:
- Priority access to GPT-4o -- faster responses, less throttling
- Unlimited image generation boosts
- Copilot in Word, Excel, Outlook, and OneNote (if you have a personal Microsoft 365 subscription -- Microsoft 365 Personal is $70/year or $7/mo)
- Access to GPT-4o with vision for image analysis
Honest take: if you already pay for Microsoft 365 Personal and you're a heavy Word/Outlook user, Copilot Pro might be worth it. The M365 integration is genuinely useful. If you're not a Word power user, Copilot Pro is a harder sell against ChatGPT Plus at the same $20/month -- ChatGPT is more capable as a general assistant even if it's more complicated to set up for document work.
3. Copilot in Windows 11 -- How to Access It
If you're on Windows 11 (version 23H2 or later), Copilot is built in.
How to open it:
- Click the Copilot icon in the taskbar (looks like a stylized C)
- Or press
Win + C - Or right-click the desktop and select "Open Copilot"
If you don't see the icon: right-click the taskbar → Taskbar settings → make sure Copilot is toggled on. On some enterprise machines, IT has disabled it via Group Policy.
What Copilot in Windows can do:
- Answer questions (general AI chat)
- Summarize open documents if you give it permission
- Control Windows settings -- "Turn on dark mode," "Connect to Bluetooth," "Take a screenshot"
- Open apps: "Open Spotify" or "Open Settings"
- Explain what's on your screen (with vision enabled)
What it can't do well: anything requiring deep file access, running code, or working with your local files beyond basic summaries. For that you need Microsoft 365 Copilot or a third-party tool.
The Windows integration is convenient but it's not transformative. It's a side panel you'll use for quick questions and occasionally for toggling settings.
4. Copilot in Microsoft 365 -- Real Use Cases
This is where Copilot gets genuinely interesting. If your org has Microsoft 365 Copilot deployed, these are the workflows worth using:
Word:
- Draft entire documents from a brief prompt: "Draft a project proposal for a website redesign based on this outline" (paste outline)
- Summarize long documents: open a 40-page report, ask "Summarize the key findings and action items"
- Rewrite sections: highlight a paragraph, ask "Make this more concise" or "Rewrite this in a more formal tone"
Excel:
- Generate formulas from plain English: "Create a formula that calculates the percentage change between column B and column C"
- Analyze data: "What are the top 5 products by revenue this quarter?" (works with your actual spreadsheet data)
- Build charts: "Create a bar chart showing monthly sales trends"
The Excel integration is my favorite -- typing out complex formulas is one of those tasks that's annoying disproportionately to how hard it actually is, and Copilot handles it well.
Outlook:
- Draft email replies: open an email thread, click Copilot → "Draft a reply" → it reads the thread and drafts a response
- Summarize long email threads: "Summarize this thread and list any action items for me"
- "Coaching" on emails you've drafted -- it'll flag tone, length, and clarity issues
Teams:
- After a meeting, ask "Summarize what was decided and list follow-up actions"
- "Who said they'd handle the Q3 budget review?" -- it searches the meeting transcript
- "Recap any topics I missed" if you joined late
I've seen the Teams integration save 15-20 minutes per meeting for teams that actually use it. The meeting summary alone is worth the cost for heavy Teams users.
5. Copilot.microsoft.com -- The Standalone Web Interface
The web interface at copilot.microsoft.com is your best option if:
- You don't have Copilot Pro or M365 Copilot
- You want to use Copilot without opening Edge or Windows 11's sidebar
- You're on a Mac or a machine without Windows Copilot access
The web version is clean. You get the chat interface, the option to switch conversation styles (Creative, Balanced, Precise -- a legacy feature from Bing AI, mostly irrelevant now), and access to image generation.
One thing the web version handles better than the mobile app: long conversations with document context. You can paste in large amounts of text and it handles it reasonably well.
Log in with your Microsoft account. Free users get the full experience; Pro subscribers get priority access and more image generation.
6. Copilot Mobile App
Available for iOS and Android. Download "Microsoft Copilot" from the App Store or Play Store -- not "Bing," which is a different app.
The mobile app is competent. Use it for:
- Quick questions on the go
- Image analysis (take a photo, ask "what is this?")
- Voice input -- tap the microphone icon for voice conversations
- On iOS, you can set it as a widget or access it from the share sheet
What doesn't work as well on mobile: anything document-heavy. Pasting a long document into the mobile chat interface is awkward. Stick to the desktop for that.
The app requires a Microsoft account to use. Sign in with the same account you use for Copilot on the web.
7. Best Prompts and Use Cases
A few prompts that actually work well:
Document summaries:
"Summarize the attached document in bullet points. Highlight any decisions that need to be made."
Email drafts:
"Draft a professional but warm response to this email declining the meeting request but offering to connect in Q2."
Data analysis (Excel/M365):
"What trends do you see in this data? Highlight any anomalies."
Research:
"What are the key differences between zero-based budgeting and traditional budgeting? Give me a balanced view."
Writing assistance:
"Rewrite this paragraph to be more direct. The current version is too passive."
General tip: be specific about format. "Give me a bullet list" or "Write this as a short paragraph" or "Format this as an email" gets better results than open-ended prompts.
8. Copilot vs ChatGPT vs Gemini -- Honest Comparison
Blunt version:
Use Copilot if: You're deeply embedded in Microsoft 365, particularly Word, Outlook, and Teams. The M365 integration is legitimately good and there's no direct equivalent from OpenAI or Google. If you're managing a team on Microsoft 365, the $30/user/month for M365 Copilot is defensible.
Use ChatGPT if: You want the best general-purpose AI assistant. GPT-4o is still the most capable model for a wide range of tasks, Perplexity-style research aside. ChatGPT Plus is better than Copilot Pro for most people who aren't Microsoft 365 power users.
Use Gemini if: You're in the Google ecosystem. Google Gemini integrates with Gmail, Docs, and Drive the same way Copilot integrates with Microsoft 365. If your team uses Google Workspace, Gemini is the equivalent product.
For coding specifically, I'd look at Cursor or GitHub Copilot over the consumer Copilot -- they're different products built for development workflows.
Copilot's weakness: it's not consistently better than ChatGPT as a general AI assistant. It's competitive. But outside the M365 ecosystem, there's no compelling reason to choose Copilot over ChatGPT for everyday use. Microsoft's real moat is the Office integration, not the underlying model.
9. Tips for Getting Better Results
A few things I've learned:
Don't use Balanced mode for creative tasks. Switch to Creative in the conversation style selector if you want more expansive, interesting outputs. Balanced defaults to conservative responses that are technically accurate but often bland.
Use the "Precise" style for research. When you need factual, citation-backed responses, Precise mode is more likely to give you that without drift.
Iterate, don't restart. Copilot holds conversation context well. Instead of starting over when a response is wrong, correct it in-thread: "That's not quite right -- the project timeline is 6 months, not 3. Please revise."
Reference documents explicitly. In M365 apps, you can tag files with @filename. Don't assume it knows which document you mean. Be explicit: "Based on the Q4 report I just opened..."
For image generation: Use Designer (formerly Bing Image Creator) from within Copilot for best results. It runs on DALL-E 3. The prompt style is similar to Midjourney -- describe the scene, style, and mood in a single prompt. For prompting guidance, check our image prompting guide.
Copilot is a solid product with a genuinely confusing brand that Microsoft has done a poor job explaining. The free tier is fine for casual use. The M365 Copilot integration is where the real value is -- if your organization is already paying for Microsoft 365 Enterprise, it's worth piloting seriously. If you're a freelancer or small team not in the Microsoft ecosystem, ChatGPT or Gemini will probably serve you better.
The branding confusion isn't going away anytime soon. Just remember: there are four Copilots, and which one you're using determines almost everything about whether it's worth your time.
