Difference Between ChatGPT, Gemini, and Copilot: Which is Better

If you’re getting into artificial intelligence, you’ve probably wondered which is better: ChatGPT, Google Gemini, or Microsoft Copilot. All three are powerful, all three are free in their basic versions, and all three do similar things but with important differences. I’ve been testing all three for months and here’s what really matters so you can pick the one that fits you best.

Quick summary: which one to choose?

If you don’t want to read the whole article, here’s my direct recommendation:

• ChatGPT → Best for creative writing, text tasks, and general versatility.
• Gemini → Best if you use Android/Google and need up-to-date information.
• Copilot → Best if you work with Microsoft Office and Windows.

Now let’s look at the differences in depth.

Full comparison: ChatGPT vs Gemini vs Copilot

ChatGPT: the most versatile

ChatGPT is the one that started the generative AI revolution, and it remains the most complete for text tasks. From writing an essay to coding an app, ChatGPT is the most flexible of the three.

Strengths

• Writing quality: It’s the best at generating natural and creative text. Its responses sound less robotic than competitors.
• Plugin and GPT ecosystem: You can create your own custom GPTs or use community ones.
• Code analysis: It’s the preferred tool for programmers due to its ability to generate, debug, and explain code.
• Memory: It remembers previous conversations and learns your preferences.

Weaknesses

• The free version has limitations and doesn’t include unlimited web search.
• It’s not integrated into any major productivity ecosystem (like Google or Microsoft).

Pro-tip: If you’re only going to use one AI tool and want the most complete one, ChatGPT is the safe bet. Its free version already covers 90% of what you need.

Google Gemini: best for Android and Google users

Gemini is Google’s bet in the AI war, and it’s especially interesting for Android users. It’s deeply integrated with the entire Google ecosystem: Gmail, Google Drive, Maps, YouTube, etc.

Strengths

• Native web search: Being Google, it has direct access to up-to-date information. It doesn’t need a special search mode.
• Android integration: It can replace Google Assistant and control your phone by voice.
• Massive context length: Gemini 2.0 can process up to a million tokens, meaning you can feed it entire books.
• Free image generation: With Imagen 3, you can create images without paying.

Weaknesses

• Its creative writing quality is slightly below ChatGPT.
• It works worse outside the Google ecosystem.

Pro-tip: If you have an Android and use Gmail, Google Calendar, and Google Maps, Gemini is the most natural option. Its system integration is unbeatable.

Microsoft Copilot: best for office work

Copilot is Microsoft’s version, based on OpenAI’s GPT-4 but with the power of the Microsoft ecosystem behind it. If your work life revolves around Word, Excel, PowerPoint, and Teams, Copilot is your ally.

Strengths

• Office 365 integration: It can create PowerPoint presentations, analyze data in Excel, and draft documents in Word.
• GPT-4 for free: Copilot offers access to the GPT-4o model without paying, which ChatGPT only does in its paid plan.
• Image generation with DALL-E 3: Also free, which in ChatGPT is paid.
• Windows integration: You can access it directly from the taskbar.

Weaknesses

• Its interface is less intuitive than ChatGPT.
• Its responses are more conservative and less creative.

Pro-tip: If you already pay for Microsoft 365, Copilot can be an incredible addition to your workflow. Even without the paid Copilot version, the free one integrated with Bing is very useful.

Which is best for each task?

It depends on what you want to do:

My personal experience using all three

I’ve been switching between all three for months and here’s what I’ve noticed:

• ChatGPT is what I use most for writing. Its responses are the most natural and creative. When I need to draft something that sounds human, I go to ChatGPT.
• Gemini is my tool for quick searches. With native web search, when I need current data (prices, news, events), I use Gemini.
• Copilot I have built into Windows and use for quick tasks: capture a screen and ask what’s on it, summarize a PDF, or generate an image.

There’s no absolute “best” one. The ideal approach is to combine them based on the task.

FAQ: Frequently asked questions

Can I use all three at the same time?

Yes, absolutely. In fact, that’s what I do. Each one has its strengths and using them complementarily gives you the best results.

Which is the cheapest to use?

All three have very complete free versions. In paid plans, ChatGPT Plus and Copilot Pro cost $20 per month. Gemini Advanced costs the same included in Google One AI Premium.

Which respects privacy best?

All three collect data to improve their services. Google and Microsoft already had your data if you used their services. OpenAI is the newest company, but it also stores conversations. Check the privacy policies if this concerns you.

Do they work well in Spanish?

Yes, all three work well in Spanish. ChatGPT and Gemini have a slight edge in fluency, but the difference is minimal for everyday use.

Conclusion

Choosing between ChatGPT, Gemini, and Copilot depends on your ecosystem and your needs. For creative writing and versatility, ChatGPT. For search and Android, Gemini. For office work and Windows, Copilot. The good news is all three are free, so try them out and stick with the one that fits you best.
