If you want one AI assistant for open-ended chat, writing, research help and experiments, ChatGPT is the more flexible starting point. If you spend your day inside Word, Excel, PowerPoint, Outlook and Teams, Microsoft Copilot is the one that works where you already work. That is the short version of ChatGPT vs Copilot, and for many people the honest answer is “both, for different jobs”.
This comparison is built for people who have to decide where to spend money or which tool to approve for a team. We checked the official plan and pricing pages from OpenAI and Microsoft on October 20, 2026. We have not run lab benchmarks and we do not name a universal winner, because the products change monthly and the model lineups behind both of them change faster than any article. Where a price or limit is not shown on the vendor page, we say so rather than guess.
One naming point first. “Copilot” now covers several things: the consumer Copilot chat app, Copilot inside Microsoft 365 apps for individuals, and Microsoft 365 Copilot for organizations. Microsoft’s own FAQ separates the first two this way: the consumer app is a conversational chat experience, while Microsoft 365 Copilot brings Copilot to apps like Word, PowerPoint, Excel and Outlook.
1. ChatGPT vs Microsoft Copilot at a glance

Both tools answer questions, draft text, summarize documents and generate images. The difference is where they live and who they are built for. ChatGPT is a standalone assistant you open in a browser or app. Copilot is an assistant that Microsoft has threaded through its own software. The table gives the practical split before we go deeper.
If you only remember one thing from this article, remember the last row. The costliest mistake we see is buying one tool and expecting it to behave like the other. Our wider list of the best AI tools shows how crowded this category is, and most teams end up running two assistants anyway.
2. What ChatGPT is and who it suits

ChatGPT is OpenAI’s assistant. OpenAI lists six plan families on its ChatGPT pricing page: Free, Go, Plus, Pro, Business and Enterprise. The free plan is described as best for trying ChatGPT, with limited uploads, image creation, voice chats and deep research. Go adds more messages, uploads and image creation, and OpenAI notes that plan may include ads. Plus is positioned for advanced work, with projects, scheduled tasks and custom GPTs. Pro is aimed at research and coding with the largest limits.
Two practical points from that page. First, OpenAI says paid plans are priced per user per month and offered monthly for Go, Plus and Business, with annual billing for Business and Enterprise. Second, the page we fetched did not display the dollar amounts as text, and the model names listed on it differed between two loads of the same page. So we are not quoting a price or a model lineup here. Check the page for your country on the day you buy. If an article tells you exactly which model you get on which plan without a date, treat it with care.
ChatGPT suits people who want one place to think out loud: freelancers, students, developers, marketers and founders. It is strong when your task does not start from a Microsoft file. Drafting a proposal from scratch, planning a content calendar, debugging a script, rehearsing an interview or turning messy notes into an outline all fit. If you want to look under the hood, our guide on the trade-offs of building on OpenAI and the walkthrough for a personal assistant on the OpenAI API show what building on the same company’s technology involves, and the OpenAI entry gives the background.
3. What Microsoft Copilot is, and why the name confuses people

Microsoft sells Copilot in layers. For individuals, the Microsoft 365 Copilot plans for individuals page lists three paid plans in US dollars: Microsoft 365 Personal at $99.99 a year, Microsoft 365 Family at $129.99 a year and Microsoft 365 Premium at $199.99 a year. All three include Copilot in the Office apps. Personal is for one person. Family covers one to six people, but Microsoft’s FAQ says AI features in Word, Excel, PowerPoint, Outlook and Designer on Family and Premium are only available to the subscription owner and cannot be shared. Premium adds advanced Copilot chat with extensive usage, agentic features such as advanced research and analytics, and extensive AI image creation. Prices are as shown on the US page on the check date and Microsoft notes yearly billing saves up to 17 percent against monthly.
For organizations, the Microsoft 365 Copilot business pricing page lists Microsoft 365 Business Standard with Copilot at $23.50 per user per month, paid yearly, and Microsoft 365 Business Premium with Copilot at $32.00 per user per month, paid yearly. Both include Copilot in Word, Excel, PowerPoint, Outlook and Teams and chat connected to work data. Business Premium adds security and identity features for up to 300 users. The page also says that if you do not have Microsoft 365 Copilot licenses yet, you can try Microsoft 365 Copilot Chat by signing in with a work account.
Notice what that means. The Copilot you get is partly a function of which Microsoft plan you already pay for. That is an advantage if you are a Microsoft shop, because the assistant arrives with the software. It is a disadvantage if you wanted to compare it cleanly with ChatGPT, because you cannot buy “just Copilot” in the same way you can buy a ChatGPT plan.
4. Everyday tasks: where each one feels better

Instead of a score, here is how we would split common jobs. These are editorial judgments, not test results, and they depend on your plan and the day’s model.
Two caveats apply to both tools. First, neither one is a source of truth. Each can produce fluent text that is wrong, so anything with a number, a legal claim or a citation needs a human check. Second, the free tiers are a taster, not a workflow. OpenAI describes its free plan as best for trying ChatGPT, and Microsoft’s consumer chat is a conversational experience, not the full in-app help that a paid Microsoft 365 plan lists. If your trial feels underwhelming, check whether you tested the tier that matches your real use.
A concrete example from our own world. Say you need to turn rough notes into meeting agenda templates for a recurring meeting. In ChatGPT you paste the notes and iterate on structure. In Copilot you can do it inside the document with the formatting already applied. Both work, and the better choice is the one that saves you the copy-and-paste step. For lighter personal use, our roundups of AI apps for everyday life and AI apps for iPhone show how many options exist beyond these two.
5. Work and productivity: Office, meetings and data

This is where Copilot’s case is strongest. Microsoft describes Copilot in Word as getting you to a first draft fast, Copilot in Excel as turning raw data into insights, Copilot in PowerPoint as going from prompt to presentation and Copilot in Outlook as summarizing your inbox. Microsoft’s FAQ adds that Copilot can apply formatting to your content, using features many people rarely touch, and that people can collaborate in real time on content generated in those apps. That last point matters on a team. A document drafted in a separate chat tool has to be pasted back before anyone else can edit it.
ChatGPT’s work case is different. OpenAI lists ChatGPT Work access on desktop for plans that include it, plus projects, scheduled tasks and custom GPTs on Plus. It suits roles where tasks do not start from a single file: analysts pulling several sources together, product people drafting user story mapping, or sales and operations staff tidying notes after a call tracking. If you work with numbers, remember that any AI-generated figure needs a check. A model can produce a confident but wrong formula, so test it against a known case such as one from our guide to calculating variance.
Meetings are a quieter difference. Microsoft’s individual plan page lists Copilot in Teams alongside all-day video calling, and its business plans list Teams with Copilot. If your team already meets in Teams, that integration reduces the number of tools in the room. ChatGPT can still help before and after a meeting, for example turning a rough agenda into talking points or a transcript you paste in into action items. The trade-off is manual transfer. Anything you paste in came from somewhere else, and the output has to be pasted back.
For finance and operations teams, the more relevant question is often not which general assistant to pick, but whether a specialist tool does the job better. Our overview of AI accounting software and AI forecasting tools covers narrower tools, and the view on enterprise AI agents shows where assistants are heading when they take actions instead of only answering.
6. Pricing and plan structure: how to compare fairly

Comparing price is awkward because the two companies sell different bundles. ChatGPT sells an assistant. Microsoft sells an Office subscription that includes an assistant. The fair way to compare is to ask what you would pay anyway.
- If you already pay for Microsoft 365: check what your current plan includes. Personal, Family and Premium all list Copilot in the Office apps, so the extra cost may be zero or only a step up to Premium for heavier use. Microsoft 365 Personal costs $99.99 a year in the US on the date we checked.
- If you do not use Microsoft 365: a ChatGPT plan is the cleaner standalone purchase. Start on the free plan, because its limits are shown on the OpenAI page and cost nothing to test.
- If you run a business: compare per-user totals. Business Standard with Copilot is $23.50 per user a month on yearly billing and Business Premium with Copilot is $32.00. ChatGPT Business is priced per user per month too, but we could not read the figure from the page, so get the quote for your region.
- Watch for ads and limits. OpenAI states the Go plan may include ads. Free plans on both sides have usage caps. Heavy users hit limits sooner than they expect.
Our advice: test the free tiers for two weeks on your real tasks before paying for either. If you want a rough cost model for building your own assistant instead, the estimates in our guide to the cost of building an AI agent give a sense of what custom work involves.
7. Privacy, security and admin control

The privacy question has two parts: what the vendor does with your data, and what your own staff do with the tool. We cannot summarize each vendor’s data terms in a paragraph without risking errors, so read the current policy for the plan you buy. What we can say is how the plan structure helps.
Both vendors separate individual plans from business plans. Microsoft markets its business plans with identity and access management, and Business Premium adds enhanced protection against viruses and phishing and discovery and classification of sensitive data. OpenAI’s comparison table lists enhanced support, dedicated onboarding and custom security review as business-tier features, not included in Free, Go, Plus or Pro. For a company, a consumer account used for work is the weak point whichever vendor you choose. Staff paste client data into whatever is easy, and a sensible policy decides which tool is allowed for which kind of data. Our guides on endpoint security and cybersecurity in digital transformation cover the wider habits, and our piece on what AI knows about you is a useful read for anyone deciding what to paste into an assistant at all.
Image generation raises its own questions. Both vendors list image creation on their plans, with limits that rise on paid tiers: OpenAI lists limited image creation on Free and more on Go, Plus and Pro, and Microsoft lists higher usage for AI images on Personal and extensive usage on Premium. Before you use generated images commercially, read the vendor’s current terms for your plan and keep a note of which tool and date produced each image. If a rights question matters to your business, ask the vendor in writing rather than relying on a blog summary, including this one.
A short checklist before approving either tool for a team:
- Decide which data types are never allowed in an assistant, such as customer records or unreleased financials.
- Use work accounts, not personal ones, for anything business related.
- Confirm who can see shared chats, files and history on your plan.
- Name an owner who reviews the vendor’s terms when plans change.
8. Which should you choose? A decision guide

Here is the practical path we would give a friend.
The point of a pilot is to replace opinion with evidence. Give five people two weeks, give them the same ten real tasks and ask them which tool saved time and which needed more cleanup. Count the corrections, not the impressions.
9. ChatGPT vs Copilot FAQs

Is Microsoft Copilot the same as ChatGPT?
No. They are separate products from different companies. Copilot is Microsoft’s assistant, available as a chat app and inside Microsoft 365 apps. ChatGPT is OpenAI’s assistant, sold through its own plans. Users sometimes notice similar behavior, but the apps, plans, limits and admin controls are different. Always judge each by its current plan page rather than by reputation.
Is Copilot free?
There is a free way to chat with Copilot, and Microsoft says organizations without Copilot licenses can try Microsoft 365 Copilot Chat by signing in with a work account. Copilot inside Word, Excel, PowerPoint and Outlook comes with paid Microsoft 365 plans. For individuals, the page we checked lists Personal at $99.99, Family at $129.99 and Premium at $199.99 a year in the US. Prices vary by region, so check yours.
Is ChatGPT free?
Yes. OpenAI says the free version is available to everyone. It limits messages with uploads, image creation, voice chats and deep research, and ranks response times as limited on bandwidth and availability. Go, Plus, Pro, Business and Enterprise add more access. OpenAI also says Go may include ads.
Which is better for Excel and spreadsheets?
If your data already sits in Excel, Copilot in Excel is the natural first test because it works on the sheet itself and Microsoft lists insight generation from raw numbers as a feature. ChatGPT is useful for explaining a formula or planning an analysis, and you can paste in a small data sample. In both cases, verify the output before using it in a report. A wrong total that looks confident is worse than a blank cell.
Can I use both?
Yes, and many people do. A common pattern is Copilot for tasks inside Office files and email, and ChatGPT for open-ended thinking, coding help and research. The cost of running both is two subscriptions or one subscription plus a free plan, so decide by tracking which one you actually open each day. Our AI image search apps roundup is one example of how many specialist AI tools can sit alongside either of them.
How often should I recheck this comparison?
At least every quarter. Plans, limits and model lineups change quickly for both products, and the OpenAI page we fetched showed different model names on two loads. Look at the dates on the vendor pages, test the free tier and compare the current plan lists before you commit money for a year.
