In brief
ChatGPT and Microsoft Copilot largely rely on the same OpenAI GPT models, but they target very different audiences. ChatGPT (OpenAI) is the consumer and creative assistant par excellence, with access to the GPT store, DALL·E for images, the Code Interpreter and plugins. Microsoft Copilot embeds the same models (GPT-5, GPT-4o) directly into Microsoft 365 (Word, Excel, PowerPoint, Outlook, Teams) as well as Windows, Edge and Bing. For a company already on Microsoft 365, Copilot becomes a cross-cutting contextual copilot. For general-purpose standalone or creative use, ChatGPT remains more versatile. Our comparison reveals the real differences beyond the shared model.

Our verdict
Draw — the two tools are evenly matched
Microsoft Copilot for Microsoft 365 isessential for companies running on Office 365: its native integration into Word (drafting a document from a brief), Excel (data analysis in natural language), PowerPoint (generating slides from a Doc) and Outlook (summarising email threads, drafting replies) delivers an immediate productivity gain. ChatGPT ismore versatile: better at creation (images via DALL·E, conversational voice), more plugins, a store of custom GPTs, and more accessible consumer pricing ($20/month vs $30/user/month for Copilot M365 in B2B). For a creative freelancer or a developer, ChatGPT Plus is more than enough. For an SMB or a large account with a Microsoft 365 licence already in place, Copilot for M365 maximises ROI on the existing stack. Many companies keep both: Copilot for office productivity, ChatGPT for R&D and creative marketing.
Frequently asked questions
Does Microsoft Copilot really use the same models as ChatGPT?
Yes, Copilot relies on OpenAI models (GPT-4o, GPT-5) hosted on Azure OpenAI. Microsoft is OpenAI’s principal investor and enjoys privileged access to its models. The difference is therefore not in the underlying LLM, but in the integration (M365 versus a standalone interface) and the data grounding (Copilot accesses your M365 files — emails, OneDrive, SharePoint).
How much does Microsoft Copilot for M365 cost?
Copilot for Microsoft 365 costs $30/user/month (about €28 excl. VAT) on top of your existing M365 licence. That is roughly $360/year per user, against $240/year for ChatGPT Plus. For a team of 50, that is $18,000/year — an investment to weigh against the real ROI on office productivity.
Is there a free version of Copilot?
Yes, Copilot in Bing/Edge/Windows is free, with a reasonable quota and access to GPT-4o. The paid Copilot Pro version at $20/month gives priority access and Word/Excel/PowerPoint features for individual use. Copilot for Microsoft 365 (the B2B offer at $30/user) is a different product and requires an active M365 licence.
Is the data I send to Copilot used to train the models?
No — Microsoft guarantees that data processed by Copilot for Microsoft 365 is not used to train OpenAI’s models. That is a key advantage over consumer ChatGPT, where conversations may be used for training (an option you can disable in settings). For companies, Copilot offers stricter contractual guarantees.
Can Copilot replace ChatGPT for content creation?
For drafting a Word document or an Outlook email, yes — it is actually better because it is contextual to your file. For multimodal creation (images via DALL·E, conversational voice, video) and standalone creation not tied to an M365 file, ChatGPT remains more complete. For a content creator, ChatGPT Plus is a better fit.
