| Features Prod Apps's expert score for the 'Features' aspect of each app. | 9.0 Microsoft Copilot has a lot of useful features. The main thing it does really well is chat with you like a helpful friend. You can ask it questions, get help with writing, or just have a conversation. You don't even need to sign up to start using it. What we really liked:
Winner in this category | 8.5 DeepSeek AI has a solid set of features that make it a great alternative to paid AI assistants. It does more than just answer questions - it's like having a smart friend who can help with pretty much anything. Here's what we really liked: 1. The AI is really smart This thing is powered by a massive AI model with over 600 billion parameters. That's a lot of brainpower! It can handle complex questions, coding problems, and analytical tasks really well. 2. It shows its work Unlike most AI assistants, DeepSeek actually shows you how it thinks through problems. This is especially helpful when you're learning something new or debugging code. It breaks everything down step by step. 3. It's completely free No catch, no hidden fees, no premium tiers. You get unlimited access to this powerful AI without paying anything. That's pretty rare these days. 4. It works everywhere Whether you're on Android or iOS, the experience is the same. No need to worry about compatibility issues. The main downsides:
But for basic AI chat and coding help, it's really solid. We give features an 8.5 - it does the core stuff really well, but could use some extra bells and whistles. | 8.0 Grok's feature set is impressive and comprehensive. The real-time information access is what really sets it apart - you can ask about current events and get up-to-the-minute answers that other AI assistants simply can't provide. The multimodal capabilities are particularly strong, with image generation that produces striking visuals and the ability to analyze uploaded images providing valuable insights. The integration with X platform is seamless and adds significant value for users already invested in that ecosystem. Grok's personality features, including its witty responses and rebellious tone, make interactions more engaging than typical AI assistants. Key Features:
However, we noticed that some advanced features are locked behind the X Premium+ subscription, which may limit accessibility for casual users. | ||||||||
| Performance Prod Apps's expert score for the 'Performance' aspect of each app. | 9.0 Microsoft Copilot works really well. The chat responses come back quickly, and the AI usually understands what you're asking for. We didn't experience any lag or crashes while using it. The image creation feature is surprisingly fast. You describe what you want, and within a few seconds, you get a picture. The quality is usually pretty good too. The voice feature works smoothly. It understands what you're saying most of the time, and the responses are clear and natural-sounding. If you use it with Microsoft Office apps, the integration works seamlessly. You can switch between Copilot and your documents without any problems. The app doesn't drain your battery too much, and it doesn't take up a lot of storage space. Overall, it performs really well for an AI assistant. Winner in this category | 6.5 Performance is a bit hit or miss with DeepSeek AI. When it's working well, it's great. When it's not, it can be frustrating. When everything is running smoothly, the app responds quickly and works without any lag. The AI processes your questions fast and gives good answers. It works consistently across different devices, so you get the same experience whether you're on Android or iOS. What works well:
The problem is that the servers seem to get overloaded a lot. You'll often see "server busy" messages, and sometimes the app just doesn't work at all. The recent drop in ratings from 4.2 to 3.98 stars suggests this is an ongoing issue. Common issues users report:
It's not the app's fault - it's more about server capacity and infrastructure. But it definitely affects how useful the app is. We give performance a 6.5 - good when it works, but the reliability issues are a real problem. | 8.0 The extension performs seamlessly, allowing you to interact with Grok without any lag or interruptions. The app handles text generation efficiently, and the image generation feature produces results quickly while maintaining good quality. The integration with X platform works smoothly, with minimal latency when accessing real-time information. Performance Highlights:
We did notice occasional performance variations, particularly during peak usage times, but these were infrequent and didn't significantly impact the user experience. The app maintains good stability across different devices and network conditions. The multimodal features, including image analysis and generation, perform consistently well, though some users have reported occasional delays with complex requests. Overall, the performance meets expectations for a modern AI assistant application. | ||||||||
| Design Prod Apps's expert score for the 'Design' aspect of each app. | 8.0 The app looks clean and modern. It's easy to figure out how to use it, even if you've never used an AI assistant before. The chat interface is simple - just type and hit send, like texting a friend. We liked how the image creation feature works. You just type what you want to see, and the app shows you the picture. It's straightforward and doesn't require any special knowledge. The voice feature has nice visual feedback - you can see when it's listening and when it's processing what you said. This makes it feel more natural to use. Overall, the design is good but not perfect. Some parts could use a bit more polish, but it gets the job done without being confusing. Winner in this category | 7.5 The design is clean and straightforward. Nothing fancy, but it gets the job done without getting in your way. We like how simple it is to use. The chat interface looks familiar - just like any messaging app you've used before. The text is easy to read, and the buttons are where you'd expect them to be. It works well on both phones and tablets, and the layout adjusts nicely to different screen sizes. The app doesn't try to be flashy, which is actually kind of refreshing. What we liked:
The downside? It's pretty basic looking. No cool animations or fancy themes. Some people might find it boring, but we think it's actually better this way - less distraction, more focus on the AI responses. We give design a 7.5 - it's functional and clean, but could use a bit more personality. | 7.0 The design is clean and functional, following modern mobile app conventions. The interface is intuitive with a familiar chat-based layout that users will find immediately recognizable. The dark theme with X's signature styling creates a cohesive brand experience that feels premium and polished. The app's visual hierarchy is well-structured, making it easy to distinguish between different types of content - text responses, generated images, and interface elements. Design Highlights:
However, we found that the design could benefit from more customization options and that the interface occasionally feels somewhat basic compared to more feature-rich competitors. The minimalist approach works well for the core functionality but may leave power users wanting more advanced interface options. | ||||||||
| Value for Money Prod Apps's expert score for the 'Value for Money' aspect of each app. | 8.0 Microsoft Copilot offers good value. You can use it for free, which gives you access to chat with AI and create images. This is actually pretty generous compared to some other AI apps. The free version is good enough for most people. You can ask questions, get help with writing, and create images without paying anything. If you want more features, there's Copilot Pro for $20 per month. This gives you:
It's worth it if you use Office a lot for work. The pricing is reasonable compared to other AI assistants. The free tier is quite good, and the Pro version offers real value for people who need the extra features. | 9.5 This is where DeepSeek AI really shines. It's completely free, and we mean completely free. No ads, no premium features, no hidden costs. What you get for free:
Compare this to ChatGPT Plus at $20/month or other paid AI services, and it's pretty amazing. You're getting similar quality for zero cost.
The only reason it's not a perfect 10 is that some people might want extra features like voice input, image generation, or plugins that you'd get with paid services. But for basic AI chat and coding help, you can't beat the value. We give value for money a 9.5 - it's basically free AI assistance that works really well. Winner in this category | 6.0 Grok's value proposition is somewhat mixed. The requirement for X Premium+ subscription ($16/month) creates a significant barrier to entry, especially when compared to free alternatives like ChatGPT or other AI assistants. However, for users already invested in the X ecosystem, Grok provides unique value through its real-time information access and distinctive personality. Value Breakdown:
The premium features, including advanced image generation and priority access, do offer tangible benefits, but the cost may be prohibitive for casual users. We found that the value is most apparent for power users who can leverage the real-time information capabilities and advanced features regularly. For occasional users or those primarily interested in basic AI assistance, the subscription requirement may not justify the cost compared to free alternatives. | ||||||||
| Ease of Use Prod Apps's expert score for the 'Ease of Use' aspect of each app. | 9.0 This is probably one of the easiest AI assistants to use. You can start chatting right away without any complicated setup. No account needed for basic features, which is nice. Getting started is simple:
We didn't need to read any instructions to figure out how to use it. The voice feature is really well done. You just tap the microphone button and start talking. It understands what you're saying most of the time, and the responses are clear. Creating images is also super easy. You just describe what you want, and the AI makes it for you. No need to learn complicated settings or options. We give it a 9 out of 10 because it's so easy to use. Even people who aren't tech-savvy should be able to figure it out quickly. Winner in this category | 8.0 This might be the easiest AI assistant we've ever used. Seriously, you can start using it right away without any setup. Download the app, open it, and start typing. That's it. No account needed, no complicated settings to figure out. It works the same way on both Android and iOS, so if you switch phones, you won't have to relearn anything. What makes it so easy:
The only annoying thing is that sometimes you get "server busy" messages when the app is overloaded. And there's not much guidance for new users on how to get the best results. But overall, it's really user-friendly. We give ease of use an 8.0 - it's super simple to use, though the occasional server issues can be frustrating. | 8.0 Grok is remarkably easy to use, especially for users already familiar with chat-based AI interfaces. The onboarding process is straightforward, and the app's core functionality is immediately accessible. The chat interface is intuitive, with clear input areas and well-organized response layouts. We particularly loved how the app handles different types of interactions - text conversations, image generation, and image analysis - all through a unified interface that doesn't overwhelm users. The integration with X platform is seamless, making it easy for existing X users to access Grok. What Makes It Easy:
However, we did notice that some advanced features might not be immediately discoverable for new users, and the subscription requirement could be clearer during the initial setup process. | ||||||||
| Security & Privacy Prod Apps's expert score for the 'Security & Privacy' aspect of each app. | 8.0 Microsoft Copilot gets an 8 out of 10 for security and privacy. Since it's made by Microsoft, it uses the same security measures that protect their other products like Office and Windows. Your conversations and the images you create are encrypted, which means they're protected from hackers. Microsoft has a good track record with keeping user data safe. If you sign in with your Microsoft account, you get extra security features like two-factor authentication. This adds another layer of protection to your account. Microsoft is pretty clear about how they handle your data. They don't sell your information to other companies, and you can control what data they collect. Just remember - like with any AI app, don't share really personal or sensitive information. While Microsoft keeps things secure, it's always better to be careful about what you share. Winner in this category | 7.0 Privacy is a mixed bag with DeepSeek AI. On the plus side, you don't need an account to use it, which means they're not collecting your email or personal info. What we liked:
The downside? It's an AI assistant, so it has to process and store your conversations to work. They probably use your chats to improve their AI model, which is pretty standard for these apps. They don't sell your data to third parties, which is good. But you should know that your conversations are being processed and stored somewhere. It's more private than apps that require accounts and collect lots of personal info, but less private than apps that keep everything on your device. We give privacy a 7.0 - reasonable for an AI assistant, but not perfect. | 7.0 Grok's security and privacy practices are generally solid, with xAI implementing standard industry practices for data protection. The app requires appropriate permissions and follows modern security protocols for user authentication and data transmission. However, we noted some concerns about data sharing practices, particularly regarding the integration with X platform and potential data usage for training purposes. Security & Privacy Features:
Users should be aware that conversations and interactions may be used to improve the AI model, which is common practice but worth noting for privacy-conscious users. The app does provide basic privacy controls, but we found the privacy policy could be more transparent about specific data usage and retention policies. Overall, the security measures appear adequate for typical use cases, though users with high privacy requirements may want to review the detailed privacy terms. | ||||||||
