HEAD-TO-HEAD COMPARISON
Two AI assistants, one question: should you use ChatGPT or Microsoft Copilot? The short answer — pick Copilot if your work lives inside Microsoft 365 and you want AI built into Word, Excel, and Outlook; pick ChatGPT if you want a standalone assistant with the broadest toolkit and no Microsoft subscription required. Both have genuinely useful free tiers, so the real test costs nothing.

ChatGPT in Detail
ChatGPT is OpenAI’s AI assistant — the product that defined the category. In 2026 it runs on the GPT-5 and GPT-6 model family: the free tier uses GPT-5.6 Luna, paid plans default to GPT-5.6 Sol, and Pro and Business tiers get GPT-6 Astra, OpenAI’s reasoning flagship. Beyond chat, a Plus subscription bundles a genuine toolkit: Codex (a coding agent), Deep Research, custom GPTs you can build and share, Projects, scheduled tasks, and memory. It works everywhere — web, iOS, Android, Windows, macOS — with no other subscription required. OpenAI is currently testing ads on the Free and Go tiers; Plus, Pro, and Business remain ad-free.

Microsoft Copilot in Detail
Microsoft Copilot is Microsoft’s AI assistant, and its defining trait is placement: it lives inside the apps where millions already work. On a paid Microsoft 365 plan, Copilot drafts and edits directly in Word, analyzes data in Excel, builds slides in PowerPoint, and summarizes threads in Outlook and Teams — without switching tabs. The free tier is a capable web-grounded chatbot (Bing-powered answers, image creation, voice, and Edge integration). Microsoft does not publish the specific model names behind Copilot, describing them only as leading models selected by Microsoft with an automatic mode that balances accuracy, speed, and cost. Note that the old standalone Copilot Pro ($20/month) is no longer listed on Microsoft’s site — paid Copilot now comes through Microsoft 365 plans.

OUR VERDICT
Editorial opinion based on publicly available information.
Copilot wins for Microsoft 365 users; ChatGPT wins as the standalone all-rounder. If your day happens in Word, Excel, Outlook, and Teams, Copilot’s in-app integration is something ChatGPT simply cannot match — the AI works where your documents already are. If you want one assistant for everything — writing, coding help, research, planning — with no Microsoft subscription and the widest built-in toolkit (coding agent, deep research, custom GPTs), ChatGPT remains the safer default. Both offer capable free tiers, so most people can simply use both and keep the one they open more.
Choose ChatGPT if you want the most versatile standalone assistant with the broadest toolkit and no Microsoft subscription required.
Choose Copilot if your work lives in Microsoft 365 and you want AI built into Word, Excel, PowerPoint, Outlook, and Teams.
Why the verdict holds
Ask where your work lives. If the answer is everywhere — mixed tasks, third-party tools, custom GPTs, no Microsoft subscription — ChatGPT is the stronger standalone pick. If your work already lives in Word, Excel, PowerPoint, Outlook, and Teams, Copilot’s built-in placement is the deciding factor.
Copilot’s advantage is placement. Drafting a document with AI inside Word — where formatting, comments, and track changes already live — beats copying text between a chatbot tab and your document. The same holds for Excel analysis, PowerPoint outlines, and Outlook summaries. For anyone whose workflow is already Microsoft-shaped, that integration is the deciding factor, and no feature list on ChatGPT’s side replicates it.
ChatGPT’s advantage is range without prerequisites. A $20 Plus subscription is complete on its own: advanced reasoning, a coding agent, deep research, image generation, voice, custom GPTs, and memory — on any device, with no Microsoft 365 plan attached. Copilot’s best features sit behind Microsoft 365 subscriptions, so a non-Microsoft user pays for an ecosystem they don’t otherwise need.
Who should pick which
- Students and casual users: try both free tiers — they’re genuinely useful, and your preference will be obvious within a week.
- Office workers on Microsoft 365: Copilot — the in-app integration pays for itself in saved tab-switching.
- Freelancers and creators on mixed tools: ChatGPT — no ecosystem lock-in, broader toolkit.
- Developers and researchers: ChatGPT — Codex and Deep Research have no equivalent on Copilot’s consumer plans.
- Companies standardized on Microsoft 365: Microsoft 365 Copilot — work-data grounding across emails, files, and Teams with enterprise controls.

ChatGPT
THE STANDALONE ALL-ROUNDER
Copilot
THE MICROSOFT-NATIVE PICK
Bottom Line
The choice is simpler than the feature lists make it look. If you already pay for Microsoft 365 — or your employer does — Copilot is the obvious companion: it meets you inside Word, Excel, Outlook, and Teams, and the free tier covers everything else. If you don’t live in Microsoft’s world, ChatGPT gives you more AI for the money as a standalone subscription, with the deepest toolkit of any assistant at $20 a month. Either way, start free: both free tiers are good enough to reveal which one you’ll actually open every day.

Frequently Asked Questions
Which is better: ChatGPT or Microsoft Copilot?
It depends on your workflow. Copilot is better if you work inside Microsoft 365 apps (Word, Excel, Outlook, Teams) and want AI built into them. ChatGPT is better as a standalone assistant with the broadest built-in toolkit — coding agent, deep research, and custom GPTs — and it requires no Microsoft subscription.
Is Microsoft Copilot free?
Yes. Microsoft Copilot has a free tier with web-grounded chat, image creation, voice interactions, and Copilot in Edge when you sign in with a Microsoft account. Paid features — like Copilot inside Word, Excel, PowerPoint, and Outlook — require a Microsoft 365 subscription (Personal starts at $9.99/month).
How much does ChatGPT Plus cost in 2026?
ChatGPT Plus costs $20/month with monthly billing (OpenAI does not offer annual billing for Plus). It includes advanced reasoning models, Deep Research, voice conversations, image generation, custom GPTs, and priority access. A cheaper Go plan ($8/month) offers higher limits than free, and Pro tiers ($100–$500/month) offer the highest usage allowances.
Does Copilot work inside Word and Excel?
Yes, but only on a paid Microsoft 365 plan (Personal, Premium, Pro, or a Microsoft 365 Copilot business license). On those plans, Copilot can draft and edit in Word, analyze data in Excel, build presentations in PowerPoint, and summarize emails in Outlook. Note that on Family plans, in-app Copilot features are available only to the subscription owner.
Which AI models do ChatGPT and Copilot use?
OpenAI names its models: the free tier uses GPT-5.6 Luna, paid plans default to GPT-5.6 Sol, and Pro/Business tiers get GPT-6 Astra. Microsoft does not publish specific model names for Copilot, describing them only as leading models selected by Microsoft with automatic per-request selection.
Can I use ChatGPT and Copilot together?
Absolutely — many people do. Use Copilot inside your Microsoft 365 documents and ChatGPT as your general-purpose assistant for research, coding help, and brainstorming. Both free tiers cost nothing, so there’s no reason to choose just one until you know which you open more.
