Merlin AI has everything you'd want in an AI assistant. It brings together seven different AI models - ChatGPT, Grok AI, DeepSeek, Gemini, Claude, and Perplexity AI - all in one place. This means you don't need separate subscriptions for each one.

We really liked the 70+ AI tools it comes with:

  • PDF summarizer
  • YouTube video summarizer
  • Image generator
  • Language translation
  • Email composition with Gmail integration

The best part is how easy it is to switch between different AI models - just one tap and you're using a different AI. Plus, everything syncs across your devices so you can start a conversation on your phone and continue it on your computer.

9.5

ChatGPT has a lot of cool features that make it useful for pretty much anyone. It's not just a chat app - it can do a bunch of different things.

What ChatGPT Does Best

1. Smart Chatting:

This is where ChatGPT really shines. It's better at having natural conversations than any other AI app we've tried. You can ask it anything from "What's the weather like?" to "Help me plan a trip to Japan" and it just gets it.

It remembers what you talked about earlier in the conversation, so it feels like talking to someone who's actually listening. You can have long conversations and it keeps track of everything.

2. Voice Chat:

This feature is really cool. You just tap the microphone button and start talking. The app shows a little wave animation so you know it's listening. It's like talking on the phone, but with an AI.

We tested this a lot and it works really well. It understands what you're saying most of the time, and responds quickly. Great for when you're driving or cooking and can't type.

3. Making Pictures:

You can tell ChatGPT to make pictures for you. Just describe what you want to see, and it creates an image. This costs money though - it's only in the paid version.

We tried asking it to make pictures of things like:

  • "a cat wearing a hat"
  • "a sunset over the ocean"
  • "a robot playing guitar"

The results were pretty good. Not perfect, but definitely usable.

4. Works Everywhere:

The best part is that your conversations follow you around. Start a chat on your phone, then open it on your computer and it's all there. Really handy when you switch between devices.

5. Photo Help:

You can take a picture of something and ask ChatGPT what it is. We tried this with:

  • Food and recipes
  • Landmarks and buildings
  • Handwritten notes

It's pretty good at figuring things out.

The main downside is that the free version is pretty limited. You only get the older AI model, which isn't as smart as the paid version. A lot of users complained about this - they want the good stuff without paying.

Performance
8.0

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.

8.0

The app runs smoothly most of the time. You can chat with the AI without any delays or problems, and it loads quickly.

The voice chat works really well too. There's almost no delay between when you speak and when the AI responds. The voice recognition is accurate, and the conversation feels natural and smooth.

However, we did run into some problems during busy times. The app can get slow or even stop working when lots of people are using it at once. This mostly affects free users since paid users get priority access.

The sync feature works great - your conversations show up quickly on all your devices. Even with long chat histories, the app stays responsive and doesn't slow down.

One area that could be better is the image generation. It can take a while to create images, especially for complicated requests. This makes sense given how much work it takes, but it can be frustrating if you're in a hurry.

The app doesn't drain your battery too much, though using voice chat will use more power than just typing. Overall, it runs well and doesn't cause problems with your phone.

Design
8.0

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.

9.0

The app looks clean and simple, which makes it easy to use right away. We really like how it focuses on the conversation instead of trying to look fancy.

What we love most is how easy it is to tell who said what:

  • Your messages show up on the right in blue bubbles
  • AI responses are on the left in gray bubbles

Simple, but it works really well.

The voice chat interface is really nice too. When you're talking, you see a little wave animation that moves with your voice. It's a small thing, but it makes you feel like the app is actually listening.

Getting around the app is straightforward. There's a simple menu button that gives you access to settings and your chat history without cluttering up the main screen.

Some people said the app looks a bit plain compared to other AI apps. We get that - it's not flashy, but that's actually what makes it work so well. You can focus on talking to the AI without getting distracted by fancy graphics.

Value for Money
9.0

Merlin AI offers great value. You can use it for free without creating an account, and you get 102 queries per day across all the major AI models.

This free access to ChatGPT, Grok AI, DeepSeek, Gemini, Claude, and Perplexity AI in one app saves you from needing multiple expensive subscriptions. The premium plan adds useful features like voice chat, advanced AI tools, and team collaboration.

The pricing is reasonable, making it a good choice for students, professionals, and anyone who wants to boost their productivity. When we compared it to individual subscriptions for these AI services, Merlin AI saves you money while offering more convenience.

You really can't find another tool that gives you this much value for so little cost.

6.0

ChatGPT has a free version that you can use without paying anything. It gives you basic chat features with the older AI model, which is fine for simple questions and casual conversations.

But the $20/month price for the good features is pretty steep. The paid version gives you:

  • The better AI model (GPT-4)
  • Image generation features
  • Priority access during busy times

That's a lot of money for an app that many people think should be free.

Some users in the reviews were really frustrated about this. They got used to the free features and then found out the good stuff costs money.

The paid version is worth it if you use AI a lot for work, school, or creative projects. The better AI model gives much more detailed and helpful responses, and the image generation can be really useful.

We think it's most valuable for people who need AI help regularly. If you just want to ask the occasional question, the free version is probably fine. But if you want to do serious work with AI, the paid features are actually worth the money.

The voice features and syncing work on both free and paid versions, which is nice. But the way they limit the free version to push people toward paying feels a bit aggressive.

Ease of Use
9.0

Merlin AI is one of the easiest AI assistants we've tried. You can start using it right away without any complicated setup. The free tier gives you 102 queries per day, which is plenty to test everything out.

Installing it is simple, and it works great on both Android and iOS. Switching between AI models is super easy - just tap to change from ChatGPT to Grok AI to Claude, and so on.

The integration with Gmail and LinkedIn works smoothly. You don't need to configure anything complicated. The free tier lets you explore all the features without committing to anything, which makes it easy to learn at your own pace.

We give it a 9 out of 10 because it's really user-friendly, though some of the more advanced features might take a bit of time to figure out.

9.0

This might be the easiest AI app to use. It works right away - no complicated setup or learning curve.

Downloading it is simple, and it works on both iPhones and Android phones. Once you open it, you can just start typing or tap the microphone to talk. That's it.

The voice feature is really easy to use:

  • Just tap the microphone and start talking
  • The app shows you when it's listening
  • It's so natural that you forget you're talking to a computer

The chat interface looks like any other messaging app you've used - WhatsApp, Facebook Messenger, etc. So it feels familiar right away. Your conversations are organized clearly, and you can easily find old chats.

Even though it has lots of features, nothing feels overwhelming. The advanced stuff like making images is there if you want it, but it doesn't get in the way of basic chatting.

The only confusing part is figuring out what's free and what costs money. The app could do a better job of showing you what you're missing out on with the free version.

That's why we gave it a 9 out of 10. It's super easy to use, though some of the fancier features take a little time to figure out.

Security & Privacy
7.0

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.

7.0

We gave ChatGPT a 7 out of 10 for security and privacy. It uses standard security practices, which is good, but there are some things to be aware of.

The good news is that OpenAI is pretty open about how they handle your data. You can easily find their privacy policy in the app, and they explain what they do with your information.

However, there are some concerns. The app collects a lot of your personal data:

  • Everything you say in conversations
  • Your voice recordings
  • Your conversation history

OpenAI says they use this to make their AI better, but that means they're storing and potentially using your private conversations.

We noticed that some users were worried about the sync feature. Since your conversations are stored on OpenAI's servers (not just on your phone), they can access everything you've said. This is what makes the cross-device sync work, but it also means your chats aren't really private.

The voice chat feature is convenient, but it also means your voice is being recorded and stored. You should know that your voice conversations could be used to train the AI.

OpenAI does give you some control - you can delete your chat history and opt out of some data collection. But these options are kind of hidden and not easy to find.

Conclusion
Merlin AI stands out as an exceptional all-in-one AI assistant that successfully combines multiple AI models with practical tools. The generous free tier makes it accessible to everyone, while the premium features offer significant value for power users. For anyone looking to consolidate their AI tools into one powerful platform, Merlin AI delivers an impressive and well-rounded experience.

ChatGPT is still the best AI chat app out there. It's really good at conversations and has lots of useful features. The free version is okay for basic stuff, but if you want the good features, you'll need to pay for the premium version.
