In the ChatGPT vs Copilot comparison, ChatGPT is the stronger standalone assistant for writing, reasoning, images and deep research, while Microsoft Copilot is the better fit if you work in Word, Excel, PowerPoint and Outlook every day. Both have free versions, and their main paid plans cost about $20 per month.
The real ChatGPT vs Copilot question is where you work. If your documents live in Microsoft 365, Copilot brings AI into those apps; if you want one flexible AI workspace, ChatGPT usually wins. Here is how they compare on models, Office integration, free tiers and prices.
Quick Verdict
- Choose ChatGPT for the most capable general assistant, more control over models, advanced deep research and creative work.
- Choose Copilot if you already pay for Microsoft 365 or want AI built directly into Office apps and Windows.
ChatGPT vs Copilot at a Glance
| Feature | ChatGPT | Microsoft Copilot |
|---|---|---|
| Maker | OpenAI | Microsoft |
| Models | OpenAI GPT-6 and GPT-5.6 families | OpenAI GPT models plus Microsoft’s |
| Free plan | Yes, limited usage | Yes, free Copilot app |
| Main paid plan | Plus, $20/month | Microsoft 365 Premium, $19.99/month |
| Cheaper paid option | Go, $8/month | Microsoft 365 Personal, $9.99/month |

ChatGPT vs Copilot: Models and Answer Quality
ChatGPT runs on OpenAI’s newest models. According to the ChatGPT pricing page, Free users get unlimited text chats with GPT-6, while Plus adds advanced reasoning models and Pro unlocks OpenAI’s top Pro reasoning. You can pick the model yourself on paid plans.
Copilot also uses OpenAI technology; Microsoft’s business pricing page highlights priority access to the latest GPT-5.X models, alongside a “model choice” feature for organizations. In our editorial judgment, both give strong everyday answers, but ChatGPT offers more depth and control for complex reasoning, long writing and research.
Office and Windows Integration
This is where Copilot shines in the ChatGPT vs Copilot matchup. With Microsoft 365 Personal, Family or Premium, Copilot works inside desktop Word, Excel, PowerPoint, Outlook and OneNote. You can draft a document from notes, summarize a long email thread, analyze a spreadsheet or turn a Word file into slides without leaving the app.
ChatGPT can do similar work, but usually outside Office: you upload a file, get the result and paste it back. That is fine for occasional tasks but slower for daily office work. If slide decks are your main need, our guide to converting Word to PowerPoint with AI shows both approaches.
Copilot is also built into Windows and the Edge browser, with an opt-in “Hey Copilot” wake word on Windows. ChatGPT offers desktop apps, but it is not woven into the operating system in the same way.
Free Tiers Compared
On a zero budget, ChatGPT vs Copilot is a fair fight. The free Copilot app runs on Windows, Mac, iOS, Android and the web. It offers web answers with sources, image creation with Copilot Imagine, Vision, voice, memory and group conversations. It does not include Copilot inside the Office desktop apps; that requires a Microsoft 365 subscription.
ChatGPT Free gives you GPT-6 chats, web search, limited image creation, limited voice and limited deep research. For pure chatting and writing, many people find ChatGPT Free the more capable of the two free options. You can learn the basics in our how to use ChatGPT guide.
ChatGPT vs Copilot Pricing
Prices last checked October 2026 (US). Note that Microsoft no longer sells Copilot Pro to new customers, per Microsoft Support; Microsoft 365 Premium is now the main option for heavy Copilot use.
| Tier | ChatGPT | Microsoft Copilot |
|---|---|---|
| Free | $0: GPT-6 chats, search, limited images and deep research | $0: Copilot app with chat, Imagine, Vision and voice |
| Entry paid | Go, $8/month | Microsoft 365 Personal, $9.99/month or $99.99/year (Copilot in Office apps, 1 TB) |
| Family | Not offered | Microsoft 365 Family, $12.99/month or $129.99/year (AI for the owner only) |
| Main AI plan | Plus, $20/month | Microsoft 365 Premium, $19.99/month or $199.99/year |
| Power user | Pro, from $100/month | No higher consumer tier |
| Business | Business, $25/user monthly or $20/user annually | Microsoft 365 Copilot Business add-on, $21/user/month annual commitment |
On paper, ChatGPT vs Copilot pricing looks almost identical at the $20 level. Microsoft 365 Premium also bundles the Office apps, up to 6 TB of cloud storage for up to six people and Microsoft Defender, so its value depends on whether you would pay for Microsoft 365 anyway. Copilot features have usage limits on every plan. Businesses should also know that Copilot Chat is included at no extra cost with eligible Microsoft 365 business plans, according to Microsoft’s Copilot pricing page.
