Review

8.3

In our review of Merlin AI - All-in-One AI Chat Assistant, we considered the categories Features, Design, Ease of Use, Security & Privacy, Value for Money and Performance. Each category was given equal importance and we'll dive into the details of each in the following section.

Features
9.0

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.

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.

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.

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.

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.

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.

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.
