The short version: Microsoft Copilot is a solid AI assistant for people already living in the Microsoft ecosystem. If you're in Word and Outlook all day, the integration genuinely saves time. If you're not, ChatGPT does most of this better.
OK, let's get into it.
First: The Naming Is a Disaster
Before I review Microsoft Copilot, I need to spend a minute on the naming situation, because it's genuinely confusing and it's caused real reader headaches. I've seen people pay for the wrong tier because they didn't understand what they were buying. So let's clear it up.
There are three "Copilots" you'll run into:
Microsoft Copilot (free) — The consumer-facing AI assistant at copilot.microsoft.com. Powered by GPT-4o. Available to anyone with a Microsoft account. This is what this review is mostly about.
Copilot Pro — A $20/month upgrade that gives you priority GPT-4o access, image generation via DALL-E 3, and the ability to use Copilot inside Microsoft 365 apps (Word, Excel, Outlook, OneNote, PowerPoint).
Microsoft 365 Copilot — The enterprise version. This is a separate add-on for business Microsoft 365 subscriptions, priced at $30/user/month (sometimes called "M365 Copilot"). It's not the same thing as Copilot Pro, even though they sound identical.
If you're a regular person evaluating AI assistants, you're dealing with the first two. If your IT department deployed something at work and called it "Copilot," that's probably the third one.
I'm reviewing the consumer product (free tier and Copilot Pro) here. The enterprise M365 Copilot is a different conversation for a different article.
The Free Tier Is Actually Pretty Good
I was skeptical going in. Free tiers from big companies are usually hamstrung just enough to be annoying.
Microsoft's free Copilot is different. It runs on GPT-4o, it doesn't throttle you aggressively, and it handles most casual use cases without nagging you to upgrade every five minutes. You get web search integration baked in -- which ChatGPT's free tier only gives you intermittently -- and it works across Windows, the web, and mobile.
The catch? No image generation on the free tier (that's locked behind Pro), and you don't get the Microsoft 365 app integrations. For most people, that's fine.
For general Q&A, research, summarization, drafting emails -- the free version holds up. I tested it against some of the same prompts I used in my ChatGPT review, and the output quality was comparable more often than I expected. Not always. But often.
Copilot Pro: Who's It For?
$20/month, same as ChatGPT Plus. And that pricing comparison is basically the whole decision tree.
If you live in Microsoft 365 -- Word documents, Excel spreadsheets, Outlook inbox -- Copilot Pro adds real value. The in-app integrations aren't just novelty features. I used Copilot in Word to summarize a 40-page contract document, and it pulled out the key clauses accurately. I used it in Outlook to draft replies to a thread I'd been ignoring for two weeks. Both worked well.
Excel is interesting. Copilot can write formulas, explain what existing formulas do, and analyze data in tables. It's not going to replace an analyst. But if you're a regular knowledge worker who's always Googling Excel formulas at 4pm, it'll save you twenty minutes a day.
PowerPoint is the one that impressed me least. "Create a presentation about X" produces something serviceable but generic. You'd still spend an hour actually making it yours.
The image generation through DALL-E 3 is... fine. It works. I've seen sharper outputs from Midjourney, but for quick visuals in a document or a presentation, it does the job.
The honest comparison: If you're paying $20/month and you're NOT in the Microsoft 365 ecosystem, ChatGPT Plus is the better buy. More customization options, Custom GPTs, more consistent output quality for general tasks. We did a full breakdown in our ChatGPT vs Microsoft Copilot comparison if you want the deep dive.
How It Actually Performs in Microsoft 365
Let me walk through the main apps.
Word
This is Copilot's strongest showing. You can ask it to draft content from scratch, rewrite selected text in a different tone, summarize long documents, or ask questions about a document you have open. The summarization is genuinely useful -- I regularly deal with long legal and technical documents, and having Copilot pull out the core points saves real time.
The drafting is decent but not great. You get serviceable first drafts, but you're still going to rewrite them. Which is fine -- that's how AI writing works in practice.
Excel
Formula assistance is the star feature. Type in plain English what you want a formula to do, Copilot writes it. This works well about 80% of the time. The other 20%, it produces something plausible-looking that's subtly wrong -- so you still need to understand what you're doing. Don't trust it blindly.
Data analysis via natural language -- "which month had the highest sales?" asked as a prompt -- works well on clean, well-structured tables. On messy real-world spreadsheets, your mileage varies.
Outlook
Summarizing email threads is the feature I use most. Long back-and-forth chains where I need the current state fast? Copilot does this well. Drafting replies is helpful for routine emails -- the ones where you're basically filling out a template anyway.
It doesn't read my personal tone well enough to replace actual writing for anything that matters. I wouldn't let it send anything important without heavy edits. But for "please reschedule our meeting" or "here's the agenda for tomorrow" -- it's fine.
OneNote and Teams
OneNote integration is useful for summarizing meeting notes. Teams integration lets you summarize meeting transcripts and get action items. These are solid enterprise features, though more relevant to the M365 Copilot tier than to individual Copilot Pro subscribers.
The Standalone Web Experience
At copilot.microsoft.com, Copilot functions as a general-purpose chatbot. And this is where it gets weaker.
It's good. It's not great. Compared to ChatGPT's full feature set -- Custom GPTs, memory across conversations, voice mode, code interpreter, deeper plugin ecosystem -- Copilot feels like it's still catching up. The web experience is clean and functional but sparse.
Web search integration is a genuine differentiator against the free ChatGPT tier. Copilot searches the web by default and shows you sources. For research questions, this matters -- you can verify where the information is coming from.
But for complex reasoning tasks, nuanced writing, coding challenges? I consistently got better results from ChatGPT. It's not dramatic. And on any given prompt the gap might flip. But across a week of testing, ChatGPT won more often.
How does it compare to Gemini? Gemini is the better choice if you live in Google Workspace the way Copilot is better for Microsoft 365. For general use, Gemini and Copilot are roughly equivalent -- different enough in specific areas that I'd test both on the types of tasks you actually care about before committing.

What I Like
The free tier generosity is real. Getting GPT-4o for free with web search built in is a legitimately good deal. Most people comparing AI assistants should at least try Copilot before paying for anything.
The Microsoft 365 integration, when you're inside Word or Outlook, feels natural. It's not a bolt-on. Someone at Microsoft actually thought through where AI could slot into these workflows without getting in the way.
If you already pay for Microsoft 365 Personal or Family, adding Copilot Pro is only $20/month and you don't need to maintain a separate ChatGPT subscription unless you need GPT's specific features. Consolidating is reasonable.
What I Don't Like
The inconsistency outside of Microsoft apps bothers me. The product feels like it was designed backward -- start with Office integration, then figure out the general AI assistant piece later. The result is an AI that's genuinely useful in some contexts and noticeably weaker in others.
The naming confusion is a real problem. When readers email me asking why their "Copilot" isn't working, half the time it's because they have the wrong tier or they're running into a Microsoft account configuration issue. If you hit that kind of problem, our Microsoft Copilot troubleshooting guide covers the most common issues.
And the customization gap is real. ChatGPT lets you configure Custom GPTs for specific use cases, adjust system prompts, and dig into memory settings. Copilot is more of a sealed appliance. You get what you get.
Pricing Summary
| Plan | Price | What You Get |
|---|---|---|
| Microsoft Copilot (free) | $0 | GPT-4o, web search, basic chat |
| Copilot Pro | $20/month | Priority GPT-4o, DALL-E 3 images, Microsoft 365 app integration |
| Microsoft 365 Copilot | $30/user/month (enterprise add-on) | Full M365 integration, Teams, enterprise controls |
The Verdict
Microsoft Copilot is a 4.1 out of 5 for the right person, and maybe a 3.2 for the wrong one.
If you're a Microsoft 365 user spending serious time in Word, Excel, or Outlook -- Copilot Pro at $20/month is money well spent. The integrations are real and the time savings are real.
If you're comparing it to ChatGPT as a general AI assistant and you don't have much of a stake in the Microsoft ecosystem, ChatGPT wins on features and consistency. Same price, more to work with.
The free tier is genuinely worth trying regardless of where you land. It's not a crippled demo -- it's a real product, and it handles everyday AI tasks competently. Start there. See if it covers 80% of what you need before you pay for anything.
And if you do run into problems, Microsoft's configuration and account requirements can be annoying. Bookmark the troubleshooting article before you need it.
