Microsoft Copilot vs. ChatGPT: What are they?

Before diving deeper into the differences between ChatGPT vs Copilot, it’s helpful to understand the core question many users have: what is Microsoft Copilot used for, and how does it compare to standalone AI tools like ChatGPT?

Microsoft Copilot is designed to enhance productivity inside Microsoft 365 apps like Word, Excel and Teams. It automates document creation, summarizes threads, analyzes spreadsheets and more. ChatGPT, on the other hand, is a conversational AI tool ideal for general-purpose brainstorming, problem-solving, and generating custom outputs.

We’ll go into more depth in a second, but at a glance, here’s how they shake out:

What is ChatGPT?

ChatGPT is a general-purpose conversational AI developed by OpenAI. Accessible from any browser or device, it handles a wide range of tasks, including writing, research, brainstorming, coding and more, without being tied to any specific platform or software suite. The ChatGPT Microsoft relationship is central to understanding both tools: Microsoft’s multi-billion-dollar investment in OpenAI means Copilot and ChatGPT often draw on the same underlying model technology, even as their delivery and use cases diverge significantly.

ChatGPT Free

The free version of ChatGPT gives you a natural language interface, to get assistance with writing brainstorming, problem solving, code development and more. ChatGPT Free users now get access to GPT-4o-mini, including basic file and image tools. It supports natural language queries, code assistance, image interpretation and limited access to tools like web browsing and file uploads. It is a solid option for casual use, but more constrained compared to paid plans.

ChatGPT Go 

ChatGPT Go launched at (and, at time of writing, is currently) $8/month and is designed for users who want expanded access to GPT-5.2 Instant at a lower price point, with 10x more messages, file uploads and image creation options than the free tier, along with a longer memory and context window.

ChatGPT Plus

ChatGPT Plus, which at time of writing is $20/month, provides priority access during high-traffic periods, offers higher GPT-5.2 limits and has access to advanced reasoning models that “think through” problems before answering. Additionally, it has access to Deep Research tools and AI generation, as well as better memory and context than lower-price tiers. There is also limited access to Sora video generation.

ChatGPT Pro

Pro, a $200/month (at time of writing) plan is for researchers, engineers, and power users. It includes unlimited access to all of OpenAI’s top models, advanced voice and the most advanced reasoning modes. You get priority access to research tools like Operator, Codex and Sora video generation. 

ChatGPT Business (formerly ChatGPT Team)

The Business subscription provides everything found in ChatGPT Plus, but includes higher message limits to GPT models and image generation tools. It allows for creating and sharing GPTs within your workspace, provides an admin console for management, includes SAML SSO, and lets you connect company docs, wikis and other tools so that responses reflect your business’ internal context. It requires a minimum of 2 users, and guarantees that OpenAI won’t train on your workspace’s data.

ChatGPT Enterprise

Enterprise offers everything in the Business plan but scaled for larger organizations with more complex needs. It includes unlimited access to OpenAI’s top models, SOC 2 compliance, advanced security and data privacy protections, analytics dashboards, directory sync and dedicated support. Pricing is custom and negotiated directly with OpenAI.

Microsoft Copilot

When comparing Microsoft Copilot vs. ChatGPT, Microsoft Copilot has many similarities to OpenAI ChatGPT. Both use natural language processing to allow users to interact with the tool in a natural way. Microsoft also uses large language models to generate responses to users’ prompts. Microsoft Copilot can also be used for a variety of different tasks from sparking creativity, doing research, generating new text writing code and more.

A common question is: does Copilot use ChatGPT? In a meaningful sense, yes – both products draw on OpenAI’s GPT model family. But Copilot is not simply ChatGPT with a Microsoft logo. It is purpose-built for productivity workflows, deeply integrated with the Microsoft 365 ecosystem and governed by enterprise-grade data protections that differ significantly from ChatGPT’s consumer offering.Microsoft Copilot

Microsoft Copilot

Microsoft Copilot is free and can be used for many things that ChatGPT is used for, such as writing emails or reports, doing research, sparking creativity and more. Copilot Chat is available at no additional cost to all Microsoft Entra ID users with an eligible Microsoft 365 subscription, and has rolled out inside Word, Excel, PowerPoint and OneNote.

Microsoft 365 Personal/Family/Premium

Replacing the former Copilot Pro tier, this is designed for individuals who want to get more out of the Microsoft Copilot product. It is a paid subscription billed monthly. Premium is for power users who want more Copilot access.

Microsoft 365 Copilot for Business

This comes in two pricing tiers. The first is a more affordable version for organizations with 300 or fewer employees (at time of writing, $21/user/month, down from the original $30); the second is for larger businesses and retains the $30/user/month price. It is comparable to ChatGPT Business, and is designed for both individuals and teams working within Microsoft 365. It includes access to the AI assistant in Excel, Teams, Outlook and Copilot agents.

Microsoft Copilot comes with many more versions. For example, there are Microsoft Copilot versions specifically for use with GitHub power platform service departments and sales organizations, to name a few. For a breakdown of all currently available Microsoft Copilots, please refer to our ebook, “Microsoft’s Copilots”.

Copilot vs. ChatGPT Pricing Comparison

Understanding the difference between Copilot and ChatGPT pricing helps organizations plan their AI investments accurately. Both platforms offer a free entry point and tiered paid plans, but their structures reflect different priorities, i.e., ChatGPT scales with individual capability and usage, while Microsoft Copilot pricing is tied to your existing Microsoft 365 licensing.

All pricing is at time of writing and subject to change. Microsoft 365 Copilot for Business requires an eligible Microsoft 365 license in addition to the Copilot add-on.

Which is Better for Business Use? 

When comparing ChatGPT versus Copilot in a business context, your choice may depend on your tech stack:

Microsoft 365 Copilot for Business is best for businesses already embedded in the Microsoft ecosystem. It integrates seamlessly with Outlook, Excel and Teams to automate repetitive workflows and boost team collaboration.

ChatGPT Business or Enterprise is more versatile across industries and platforms. It’s not tied to a specific suite of software, so it’s ideal for teams using multiple tools or needing custom GPTs for proprietary workflows.

Ultimately, ChatGPT offers more flexibility, while Copilot delivers more embedded, task-specific support.
