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

Claude has a lot of useful features:

• Quick answers to questions
• Step-by-step help for complex tasks
• Upload and analyze images or files
• Works on phone and computer, always in sync

It’s great for writing, research, or just getting things done. We liked how Claude could give both short and detailed answers. The file and image tools were handy, and we felt safe using it because of the privacy focus. The main downsides: chat limits can be annoying, and you need to pay for some extras. We also wish it remembered more between chats.

Overall, Claude has most of what you need for work or personal use. We give features an 8.0.

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.

ChatOn AI has a really impressive set of features that goes way beyond just chatting with AI. We found it can handle text generation, image creation, document analysis, and lots more - basically everything you'd want from an AI assistant.

Here's what we liked most:

• Multiple AI Models: You get access to GPT-4o, Claude 3.7, DeepSeek-R1, and others, so you can pick the one that works best for your needs
• AI Image Generation: You can create custom pictures and artwork right in the app, which is pretty cool
• Photo Effects: Transform your photos with fun styles like Japanese Cartoon, Plushy, and Cyberpunk looks
• Document Analysis: Upload documents and get summaries, translations, and answers to questions about the content
• YouTube Help: Paste a YouTube link and get summaries or ask questions about the video
• 100+ Ready Prompts: Lots of pre-written prompts to help you get started quickly
• Writing Help: Get assistance with emails, social media posts, speeches, and creative writing
• Code Generation: Write and debug programming code with AI help

But we did run into some issues. Recent updates seem to have caused performance problems - the app sometimes freezes up or needs to be restarted to work properly. Also, the image generation feature, while cool in theory, doesn't always give you what you ask for.

The free version is pretty limited, which makes sense but might be frustrating if you want to test everything before paying. We give features an 8.0 - great variety and innovation, but the reliability could be better.

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.

ChatOn AI's performance is the biggest problem we found. Recent user feedback shows serious reliability issues that make the app frustrating to use, and these problems seem to have gotten worse after recent updates.

What works well when it's running:

• Fast Responses: When it's working, the AI responds quickly
• Multiple Models: The app handles different AI models without conflicts
• Image Processing: Photo effects and image generation work efficiently when they work
• Document Handling: File uploads and analysis work fine under normal conditions

But there are major performance issues:

• Frequent Crashes: The app often freezes up and needs to be restarted
• Response Problems: Users get stuck on "thinking" status and never get responses
• Update Issues: Problems seem to have increased after recent app updates
• Inconsistent Reliability: The app works differently from one session to the next
• Affects Everyone: Both free and paid users are experiencing these problems

These performance problems have been going on for weeks, and some users say the app has become basically unusable. The developers don't seem to be responding quickly to fix these issues.

While ChatOn AI has the potential to perform well based on its features and user base, the current reliability problems make it hard to use. We give performance a 5.5 - below average due to persistent stability issues.

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.

ChatOn AI has a clean, modern look that does a good job organizing all its features. The interface is easy to navigate and looks professional, though there are a few areas that could be improved.

What we liked about the design:

• Clean Layout: The chat interface is straightforward and easy to use, with clear separation between different AI models and features
• Good Organization: Important features are easy to find, and the 100+ ready prompts are prominently displayed
• Works on Different Screens: The app adapts well to different phone sizes and orientations
• Nice Colors: The black theme looks professional and is easy on the eyes
• Logical Grouping: Tools are organized in a way that makes sense - image generation, document analysis, etc.

Some things could be better though. The interface can feel a bit crowded when you're using advanced features, and some users say the image generation interface could be more intuitive. The transitions between different AI models and features could be smoother too.

Overall, the design is solid and functional, though not particularly groundbreaking compared to other AI apps. We give design a 7.5 - it works well and looks good, but could use some polish.

Claude’s free version is really good. You can do a lot without paying, and there are no hidden costs or ads. If you want more—like longer chats or extra features—you’ll need to pay, and it can get expensive.

If you use Claude a lot, the paid plans are worth it. But if you just need it now and then, the free version is enough. Some people might find the price high, and chat limits in the free version can be a pain. We give value for money a 7.8.

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.

ChatOn AI's value is complicated and really depends on your experience with the app. Some users get great value, while others feel ripped off due to performance issues and subscription problems.

What makes it good value:

• Lots of Features: You get text generation, image creation, document analysis, and more in one app
• Multiple AI Models: Access to GPT-4o, Claude 3.7, and other advanced models in one place
• Free Trial: You can test basic features before paying
• Regular Updates: The app gets new features and improvements regularly

But there are some real problems:

• Subscription Issues: Many users report trouble unsubscribing and unexpected charges
• Performance Problems: Recent updates have made the app less reliable, which hurts the value of paid features
• Limited Free Version: The free tier is pretty basic, so you have to pay to really test it
• Inconsistent Image Generation: The AI image feature, which is a key selling point, doesn't always work well
• Confusing Pricing: While prices are shown ($4.99-$59.99), the subscription model can be confusing

The value really depends on whether you run into the performance issues. If everything works smoothly, the features justify the cost. But the combination of reliability problems and subscription issues really hurts the overall value.

We give value for money a 6.0 - potentially good value when it works, but the problems make it hard to recommend confidently.

Claude is super easy to start with. We were chatting in seconds, and everything was where we expected. Adding files or switching devices was simple.

We liked how easy it was to pick up a conversation or start something new. The only thing that got in the way was having to repeat ourselves sometimes, since Claude doesn’t remember past chats. Chat limits can also stop longer talks. Still, for most things, Claude is smooth and easy. We give ease of use an 8.5.

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.

ChatOn AI is generally pretty easy to use, especially for an app with so many features. It does a good job making advanced AI capabilities accessible to everyone, though recent performance issues have made it less reliable.

What makes it easy to use:

• Familiar Chat Interface: The chat-based design makes it easy to talk to AI without a steep learning curve
• Ready-Made Prompts: The 100+ pre-written prompts help you get started quickly and discover new features
• Easy to Find Features: Important tools like image generation and document analysis are easy to access
• Simple Model Switching: You can easily switch between different AI models to find the best one for your needs
• Quick Setup: Getting started takes almost no time at all

But we ran into some problems during testing. Recent updates seem to have made the app less reliable - it often freezes up or needs to be restarted to work properly. This really hurts the ease of use since you can't count on it to work consistently.

Some of the more advanced features like image generation and document analysis have interfaces that could use better tutorials or guides. The free vs premium feature split can also be confusing.

When it's working properly, ChatOn is very easy to use. But the current reliability issues make it frustrating. We give ease of use a 7.0 - good when it works, but the performance problems really get in the way.

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.

Gemini uses Google’s usual privacy and security rules.

• Your data is handled by Google’s privacy policy
• You can check the details in the app
• No privacy problems or weird permissions in our tests

Like other Google apps, some data is collected to make things work better. If you care a lot about privacy, it’s worth reading the policy. We like that you can change some privacy settings, but this isn’t an offline or anonymous tool.

ChatOn AI's approach to security and privacy is a mixed bag, which is pretty typical for AI assistant apps. There are some good things, but also some concerns you should know about.

The good stuff:

• Reputable Company: It's made by AIBY Inc., a real company based in Miami, Florida, which gives some accountability
• Clear Support: You can contact them at support@aiby.com with questions or concerns
• Transparent Pricing: The costs are clearly shown, ranging from $4.99 to $59.99
• Age Appropriate: It's rated "Teen" which means it has content filtering

But there are some privacy concerns to be aware of:

• Data Processing: Since it's an AI assistant, it has to process your conversations, documents, and images to work - this means your info goes to AI models
• Multiple AI Providers: Your data gets processed by different AI companies (GPT-4o, Claude 3.7, etc.), each with their own privacy policies
• Document Analysis: When you upload documents for analysis, that content gets processed
• Image Generation: Your prompts and uploaded images are used to create content

The app could be more transparent about its privacy policy and how it handles data. You should be careful about what sensitive information you share, since your conversations and files get processed by third-party AI services.

We give security and privacy a 6.5 - okay for an AI assistant, but be careful with sensitive information.
