ChatGPT vs Microsoft Copilot: pricing and free tier side by side

ChatGPT vs Microsoft Copilot

Amo and Pimi: Which one to choose between these two

Amo

Let's nail down the timeline first, so we don't get confused again — Microsoft's grace period for legacy Copilot Pro subscribers ran through August 1st, and that date has already passed. The site has now pulled this plan entirely — nobody will be a Copilot Pro subscriber anymore.

Pimi

Let me confirm — don't be so fierce. Yes, standalone Copilot Pro has been discontinued and the grace period has ended; to use advanced Copilot features now you need Microsoft 365 Premium, US$19.99/month or US$199.99/year — nearly the same price as ChatGPT Plus's US$20, see, not that different.

Amo

The prices are close, sure, but don't deliberately conflate them – Microsoft 365 Premium also includes the full Office apps and up to 6TB of cloud storage, not just an AI chat feature on its own.

Pimi

This is actually a great deal for people who already use Word, Excel, and Outlook — the AI features basically come bundled free with Office, no extra subscription needed. Why do you always have to find fault?

Amo

I'm not nitpicking, I'm telling the truth. If you don't use Office at all and just want an AI assistant, for the same money ChatGPT gives you a product purpose-built for conversation, image generation, and voice — far more concentrated in features than a bundled model like Copilot.

Pimi

Fine, I'll grant you that point. Chinese support is labeled "full" on both sides' data — that's a tie. The free plans on both sides also give basic text chat you can use right away without paying immediately — finally, one thing we don't have to argue about.

Amo

The main difference is use case, not which one is better or worse – Copilot's whole reason for existing is explicitly written as 'office integration'; step outside the Office ecosystem and it loses most of its edge. You can't really argue with that.

Pimi

I'm not disagreeing, I'm adding to it! In the same category you could also look at DeepSeek, which goes the free-web-plus-super-cheap-API route, or Comet, which focuses on browser integration. The four tools each fit a different use case, so there's no clear winner — see, we ended up agreeing after all.

So the conclusion is

ChatGPT and Microsoft Copilot have similar pricing for their personal editions: ChatGPT Plus costs US$20/month, while Copilot's main plan, Microsoft 365 Premium, costs US$19.99/month (or US$199.99/year), making them almost identical in price. However, Copilot's paid plan is bundled with Office applications and up to 6TB of cloud storage. The standalone version, Copilot Pro, was discontinued at the end of 2025, and the subscription buffer period for existing subscribers ended on August 1, 2026, meaning there are no more Copilot Pro subscriptions available (the plan has been completely removed from the website). In contrast, ChatGPT Plus is a pure AI conversation, Image generation, and voice subscription that does not include office software. Both websites indicate complete support for Chinese. Simply put, for those already using Office, choosing Copilot means AI is an added value, while for those who only need an AI assistant, ChatGPT's features are more concentrated, and there is no difference in quality - it just depends on the usage scenario.
