- Image generation with DALL-E 3 — free image generation with 15 boosts/day, unlimited slower generation
- No usage caps on free tier — unlike ChatGPT Free, Copilot doesn’t throttle you after heavy use
- Windows 11 native — built into the taskbar, accessible via Copilot key on new keyboards
- Voice mode — natural voice conversations built in
- Free with no hard usage limits
- Always has current web data
- Deep Microsoft 365 integration
- Excellent for research with citations
- Image generation included free
- Less customizable than ChatGPT
- No persistent memory (yet)
- Can feel more conservative/filtered
- Plugin ecosystem less mature
- Microsoft 365 features require Copilot Pro
What Is ChatGPT?
ChatGPT from OpenAI is the original AI assistant that kicked off the modern AI revolution in late 2022. It remains the most capable and flexible AI chatbot available, with access to multiple models, memory features, custom GPTs, and an advanced code interpreter.
ChatGPT’s key advantages:
- Multiple model access — GPT-4o for everyday tasks, o1 and o3-mini for deep reasoning and math
- Persistent memory — ChatGPT remembers things across conversations (toggleable)
- Advanced Data Analysis — upload CSVs, spreadsheets, PDFs and get real analysis, charts, and insights
- Custom GPTs — thousands of community-built AI agents for specific tasks
- DALL-E 3 image generation — included in Plus, with more monthly credits
- ChatGPT API access — developers can integrate ChatGPT into their own apps
- Voice mode with vision — advanced audio features, can analyze what it “sees” via camera
- Access to reasoning models (o1, o3)
- Persistent memory across sessions
- Best code interpreter available
- Huge custom GPT ecosystem
- More customizable and flexible
- Free tier has usage limits
- Web search less seamless than Copilot
- Knowledge cutoff (without browsing enabled)
- No native app ecosystem integration
- More expensive for Pro features

Use Case Breakdown
For Research and Fact-Checking
Winner: Microsoft Copilot. Copilot’s always-on Bing integration means it cites sources by default, shows you where information came from, and pulls current data. For research tasks, this beats ChatGPT’s sporadic web browsing mode. You get a more Wikipedia-style, sourced response.
For Writing and Content Creation
Winner: ChatGPT. ChatGPT’s outputs tend to be longer, more nuanced, and more stylistically flexible. Memory means it can learn your preferences over time. Custom GPTs like “Humanizer” or specialized writing tools add extra capability. For serious content work, ChatGPT Plus is the better tool.
For Coding
Winner: ChatGPT — by a wide margin. ChatGPT’s Advanced Data Analysis (formerly Code Interpreter) can execute Python, analyze data, create charts, and debug code in a sandboxed environment. The reasoning models (o1, o3) are dramatically better at complex programming problems. For developers, also check out our comparison of Cursor vs GitHub Copilot — dedicated AI coding tools often beat general AI assistants for in-editor work.
For Microsoft Office Users
Winner: Microsoft Copilot Pro. If you live in Word, Excel, Outlook, and Teams, Copilot Pro’s $20/month delivers AI that works inside your actual apps. Draft emails in Outlook, summarize meetings in Teams, generate charts in Excel from natural language — nothing ChatGPT can match natively.
For Data Analysis
Winner: ChatGPT Plus. Upload a CSV, ask ChatGPT to analyze trends, create visualizations, and export cleaned data. The code interpreter is genuinely impressive. Copilot can do some of this inside Excel with Copilot Pro, but the ChatGPT standalone experience is more flexible.
For Image Generation
Winner: Tie (slight edge to Copilot for free users). Both use DALL-E 3. Copilot gives free users 15 fast-generation “boosts” per day plus unlimited slower generation — more generous than ChatGPT’s gated approach. For volume image generation, Copilot’s free tier wins.
Pricing Deep Dive
Microsoft Copilot Pricing
- Free: Copilot.microsoft.com — unlimited, GPT-4o, web search, image generation
- Copilot Pro ($20/month): Priority access to the latest models, Microsoft 365 integration (Word, Excel, PowerPoint, Outlook, Teams), faster image generation
ChatGPT Pricing
- Free: GPT-4o access (limited), basic features, no memory, limited messages
- ChatGPT Plus ($20/month): Unlimited GPT-4o, access to o1 reasoning model, DALL-E 3 image generation, Advanced Data Analysis, custom GPTs, memory
- ChatGPT Pro ($200/month): Unlimited o1 access, o3-mini, unlimited voice, priority compute — for power users only
Value assessment: At $20/month, ChatGPT Plus delivers more raw capability for power users. Copilot Pro delivers more practical value if you use Microsoft 365 daily.
The Underlying Tech: Are They Really Different?
Both products use GPT-4o from OpenAI as their base model. So why do they feel different?
- System prompts: Microsoft has customized Copilot’s behavior — it’s more conservative, citation-focused, and search-integrated
- Access to models: ChatGPT has o1 and o3 reasoning models that Copilot doesn’t expose to users
- Context windows: ChatGPT Plus users get larger context windows for longer documents
- Memory: OpenAI has built persistent memory into ChatGPT; Copilot currently lacks this
- Tooling: ChatGPT’s sandbox environment for code execution is more mature
For AI coding assistants specifically, neither Copilot nor ChatGPT is optimized for in-editor coding workflows. See our roundup of Best AI Coding Assistants 2026 for tools purpose-built for developers.
Final Verdict
- Choose Microsoft Copilot if you’re a Windows/Microsoft 365 user who wants AI assistance built into your existing tools, without paying anything extra. The free tier is exceptionally generous.
- Choose ChatGPT Plus if you’re a power user, developer, content creator, or researcher who needs the most capable AI models, persistent memory, and advanced data analysis. The $20/month investment pays for itself quickly for heavy users.
- Use both free tiers and see which fits your workflow — there’s no cost to try.
The short answer for most users: start with Copilot’s free tier (it’s more generous and zero cost), and upgrade to ChatGPT Plus if you find yourself wanting more power, memory, or coding capabilities.
FAQ
Is Microsoft Copilot free?
Yes — Microsoft Copilot is completely free at copilot.microsoft.com. It includes unlimited GPT-4o chats and image generation with no hard usage limits. Copilot Pro ($20/month) unlocks Microsoft 365 integration and priority model access.
Is Copilot better than ChatGPT?
For casual use and Microsoft 365 integration, Copilot is arguably better (and free). For power use — complex reasoning, coding, data analysis, and customization — ChatGPT Plus is superior. They’re not head-to-head competitors so much as tools with different strengths.
Does Microsoft Copilot use GPT-4?
Yes — Microsoft Copilot uses GPT-4o, the same base model as ChatGPT. Microsoft is a major OpenAI investor and licensee. The differences are in how each company has tuned and deployed the model.
Which AI is better for coding?
ChatGPT Plus is better for coding tasks due to its Advanced Data Analysis (code execution sandbox) and access to reasoning models (o1, o3) that are significantly better at complex programming. For in-editor AI coding, consider dedicated tools like Cursor or GitHub Copilot.
Can I use both Copilot and ChatGPT?
Absolutely — many power users use both. Copilot for quick research with citations, ChatGPT for deep work, coding, and content creation. With both free tiers, there’s no reason not to have access to both.
