It's a split decision.
Choose Microsoft Copilot if you want web-grounded answers and work features tied to Microsoft accounts. Choose OpenAI if you want ChatGPT or an API platform, and a lower-priced paid entry point: ChatGPT Go is $8/month, while Microsoft 365 Premium works out to $16.67/month on annual billing. Both offer free plans, but exact Copilot message caps are unpublished and ChatGPT Free has limited daily quotas for several tools. Check business license requirements and seat minimums before buying.

02Pricing compared
Both offer free plans, but the paid entry points differ. OpenAI lists ChatGPT Go at $8 per month and ChatGPT Plus at $20 per month. Microsoft lists Copilot Pro at $20 per user per month; Microsoft 365 Premium is $19.99 monthly or $16.67 per month with annual billing. Premium includes Copilot, but its Copilot features apply to the subscription owner only.
For teams, Microsoft 365 Copilot Business lists an annual rate of $21 per user per month and a monthly rate of $25.20. It requires a qualifying Microsoft 365 Business license and supports up to 300 seats. ChatGPT Business Standard lists $20 per user per month annually or $25 monthly, with a two-user minimum and 200-user maximum. Check the underlying license costs: they are not included in these listed Copilot prices.
03Features and depth
Copilot is positioned around everyday assistance and Microsoft workflows. Its listed features include conversational answers, web search with grounded answers, drafting, image generation, summaries, and finding work files and insights. Microsoft also says work and personal chats, files, and protections stay tied to the appropriate account. The free plan includes 15 Designer image boosts per day; exact message caps are not published.
OpenAI’s offering spans ChatGPT, ChatGPT Business, and an API Platform, alongside AI research. Its plan details list tools such as uploads, image generation, voice, browsing, Codex, and deep research, though availability and quotas vary by plan. Plus includes advanced reasoning, deep research, and custom GPTs; Free has limited daily quotas for several tools. The API Platform gives OpenAI a distinct option for teams building with its services, but API pricing is not included on the vendor's site. For Microsoft-connected work, Copilot’s account and file features are the clearer fit; for ChatGPT tools or API access, OpenAI covers more ground.
04Ease of use and learning curve
Copilot’s free tier requires a signed-in Microsoft account. Its separate work and personal accounts may help keep chats and files in the right context, but paid work access can mean checking license eligibility first. Microsoft 365 Copilot Business requires a qualifying Business base license, and Enterprise Copilot also requires a qualifying base license.
ChatGPT offers individual plans as well as Business, Enterprise, and Edu options. The Business plan has a two-user minimum; Enterprise and Edu pricing is custom. OpenAI also lists an API Platform, which is a different route from using ChatGPT and may require a separate buying decision. For an individual, ChatGPT Go is the lowest listed paid plan. For a team already using eligible Microsoft 365 licenses, Copilot may involve fewer new account decisions, but the published details do not establish which product is easier to learn.
Questions people ask
Which is better, AI Copilot or ChatGPT?
It depends on the job. Copilot lists web-grounded answers, image creation, summaries, and Microsoft work features. ChatGPT offers several individual tiers, business plans, and an API Platform. Compare the tools and limits you need: Copilot’s exact message caps are unpublished, while ChatGPT Free has limited daily quotas for several tools.
Are there other apps like Copilot?
ChatGPT is one alternative in this comparison, and OpenAI also lists an API Platform for building with its services. The published product information does not establish which other apps match Copilot’s features, so we would compare specific needs—such as web answers, Microsoft account workflows, or API access—before choosing.
What are the drawbacks of Copilot?
The main buying uncertainty is usage: Microsoft does not publish exact message caps for the listed Copilot plans, and the free tier’s model access may be limited at peak hours. Business and Enterprise plans also require qualifying Microsoft 365 licenses, whose costs are not included here.
Which is better than ChatGPT?
There is no single winner in the published details. Copilot is a stronger fit to consider for Microsoft account and work-file features; ChatGPT is the option to consider for its listed reasoning tools, custom GPTs, and API Platform. Check plan limits and required licenses before deciding.
