Most buyers should pick ChatGPT.
Pick ChatGPT if price is the deciding factor: its Go plan is $8/month, while Copilot’s listed paid entry is $16.67/month on annual Microsoft 365 Premium billing. Choose Copilot if your work already centers on Microsoft accounts, files, and workflows; it also offers a work/personal account split. ChatGPT has a broader plan ladder and a lower-cost paid option, but both products leave important usage caps unpublished. For teams, compare required base licenses and seat minimums, not just per-user rates.

02Pricing compared
ChatGPT is cheaper if you want a paid plan without a Microsoft 365 bundle: its Go plan is $8 per month. Copilot’s Microsoft 365 Premium works out to $16.67 per month with annual billing, or costs $19.99 month to month; Copilot Pro is $20 per user per month. Premium and Pro are different subscriptions, and Pro needs a separate qualifying Microsoft 365 Personal or Family subscription for Copilot in desktop Office apps.
For teams, ChatGPT Business is $20 per user per month with annual billing or $25 month to month, with a two-seat minimum. Microsoft 365 Copilot Business is $21 per user per month annually or $25.20 monthly, and requires a qualifying Microsoft 365 Business license. Both products leave important usage caps unpublished, so compare the required licenses and limits, not just the headline rate.
03Features and depth
Both assistants handle conversational questions and content creation. Copilot also lists web search with grounded answers, information summaries, image generation, and separate work and personal accounts. That split is useful if you want work chats and files kept with the appropriate account. Microsoft’s pricing details add another consideration: Copilot features in Microsoft 365 Premium apply to the subscription owner, even when the plan covers up to six people.
ChatGPT lists image generation, file and image uploads for tailored responses, saved chat history, and a separate Deep research option. Its paid plans add features such as advanced reasoning models, projects, scheduled tasks, and custom GPTs on Plus. The homepage lists a Plugins tab but does not detail which plugins are available. Neither product publishes exact caps for several key features, including everyday message limits on free plans. ChatGPT offers more plan tiers; Copilot’s feature case is clearest when Microsoft accounts, files, and workflows matter.
04Ease of use and learning curve
Both products are designed for natural-language interaction: ChatGPT’s core workflow is typing a question and getting a conversational answer, while Copilot describes its chat as a place to ask questions and work through projects. The published product details do not publish setup steps or learning-time comparisons, so we would not claim one is objectively easier to learn.
The more practical difference is where your work lives. Copilot offers separate work and personal accounts, and its work features depend on qualifying Microsoft licenses. ChatGPT’s logged-in users can upload files and images and use saved chat history. If you only want to ask questions, either starts with a chat interface; if you need work files or team controls, check the account and license requirements before switching.
