Compare Microsoft Copilot, Merlin AI, and Google Gemini: Which App is the Best?

Gemini is packed with things you can do:

• Get help with homework
• Make images
• Plan trips
• Connects with Google services like Search and Maps

If you pay for Pro or Ultra, you get even more, like video generation and deep research.

But not everything works everywhere. Some features, like video-to-talk, didn’t show up on all our devices. And if you’re used to the old Google Assistant, you might miss a few things. Still, the basics work well and Gemini keeps getting better. Just check if the features you want are available for your phone.

We think Gemini’s features are strong, but we’d like to see them work the same for everyone.

The app runs smoothly without lag or interruptions when chatting with multiple AI models. The search function works quickly and accurately, so you can easily find your conversations.

We tested it on different devices and platforms, and it performed well everywhere. The chat responses are fast, even when switching between different AI models. The cross-device sync works reliably, so you can start a conversation on your phone and pick it up later on your computer.

The integration with Gmail and LinkedIn works well without delays. We did notice some occasional loading times when processing complex requests or large documents, but overall the performance is consistent and reliable for everyday use.

The best part is that basic features work offline, so you can access your conversations even without an internet connection.

Gemini runs smoothly.

• App opens fast
• Answers come quickly
• No crashes or slowdowns in our tests

Some features aren’t on every device yet, but that’s not a speed issue. For what’s there, everything works as it should.

The app looks clean and modern. It's easy to find what you need without getting lost in menus. The chat interface is well-designed with clear differences between responses from different AI models.

We liked how the app works the same way whether you're on Android, iOS, or desktop. It adapts nicely to different screen sizes. The dark and light theme options are a nice touch, and you can customize the interface to your liking.

The mobile version works really well too - you can easily access your AI conversations on your phone without any issues.

Gemini gives you a lot for free:

• Main features work without paying
• Extras like video generation need Pro or Ultra
• Most people won’t need to upgrade right away

The free version is generous, and the paid plans are fair for what you get. There are no hidden fees.

Gemini is easy to get started with.

• Menus are clear
• Main features are easy to find
• No manual needed

Some features only work on certain phones or in some countries, which can be confusing. We also wish you could talk to Gemini without always opening the app. But for most things, it’s simple and quick.

For security and privacy, we give Merlin AI a 7 out of 10. The app uses standard encryption for your conversations and personal data, which is good.

However, since it connects to multiple AI providers, your data might be shared with these third-party services. This is mentioned in their privacy policy, but it's something to be aware of. The app doesn't ask for unnecessary permissions, but remember that your conversations and any documents you upload are processed by external AI services.

While the company is transparent about how they use data, we would have liked more control over what gets shared with which AI providers. They do a good job of being upfront about it, but some users might want more control over their data.
