The Bottom Line#
ChatGPT is the better standalone assistant. It gives you projects, scheduled tasks, custom GPTs, deep research, Codex, and ChatGPT Work, with no Office subscription needed.
Copilot is the better choice if you already pay for Microsoft 365. It works inside Word, Excel, PowerPoint, Outlook, and Teams, and its business plans can ground answers in your company's data. ChatGPT cannot replace that without extra setup.
The decision is simple: if your documents and email are in Microsoft 365, pick Copilot. If they are not, pick ChatGPT.

How We Built This Comparison#
We read the official plan pages from OpenAI and Microsoft on November 9, 2026. We did not run our own tests. OpenAI's pricing page shows amounts by region and does not expose them in a form we could verify, so we link to chatgpt.com/pricing instead of quoting ChatGPT subscription prices.
Is Copilot Better Than ChatGPT?#
Only inside Microsoft 365. Copilot's advantage is that it sits in the apps where your documents and email already are. For anything outside that environment, ChatGPT offers more tools.
Which Copilot Are We Talking About?#
Microsoft uses the name for several products, which causes most of the confusion:
- Free Copilot is the chat app anyone can use.
- Microsoft 365 Personal, Family, Premium, and Pro are consumer subscriptions that include Copilot with rising usage limits.
- Microsoft 365 Copilot Business is an add-on for companies that also grounds answers in work data.
GitHub Copilot is a separate product for developers. For that one, see Cursor vs GitHub Copilot.
Who Should Choose Which?#
Choose ChatGPT if you do not use Microsoft 365, want scheduled tasks and custom GPTs, or want Codex and ChatGPT Work included.
Choose Copilot if you already need Word, Excel, and Outlook. Microsoft 365 Personal includes those apps and Copilot in one subscription, so the AI feature costs less than a separate subscription would.
Choose Copilot Business if your team needs answers based on its own SharePoint files, email, and meetings.
Choose both if you use Microsoft 365 at work and want a separate assistant for writing and research outside it.
Feature-by-Feature#
Everyday Assistant Features#
ChatGPT offers projects, scheduled tasks, custom GPTs, deep research, memory, voice chats, and image creation. Free users get limited access to most of these, and Plus and Pro expand them.
Copilot offers advanced chat, visual assistance from your screen or camera, AI-generated audio in English, and AI image creation, with usage rising from Personal to Premium.
Winner: ChatGPT. More of its features are designed around ongoing work, such as projects and scheduled tasks.
Office and Document Work#
ChatGPT can work with files you upload and connected apps, but it does not sit inside Office.
Copilot is built into Word, Excel, PowerPoint, Outlook, and Teams. On consumer plans, you can use Copilot in select apps with work files. Business plans add AI chat grounded in your work data, along with a choice of models.
Winner: Copilot. This is the reason to buy it.
Agents and Automation#
ChatGPT includes ChatGPT Work, with expanded access on Plus and longer sessions on Pro. Pro also includes Dot, an always-on agent.
Copilot offers limited agentic usage on Microsoft 365 Premium and the highest usage on Microsoft 365 Pro. Business plans list Cowork, Autopilot, and pre-built agents for research and data analysis, with usage-based billing for select advanced features.
Winner: ChatGPT for individuals. Copilot for companies that already run on Microsoft 365.
Models#
ChatGPT uses OpenAI's GPT-6 family. Plus includes GPT-6.1 Sol and GPT-6 Astra.
Copilot business plans offer AI chat grounded in your work data with a choice of large language models, according to Microsoft's plan page. Microsoft's consumer plan pages do not name the models.
Winner: ChatGPT for transparency. OpenAI tells you which models each plan includes.
