Compare Claude, Google Gemini, and Grok - AI Assistant by xAI: 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 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:

• Fast text generation responses
• Quick image generation with good quality
• Smooth X platform integration
• Stable across different devices
• Good network performance

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.

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 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:

• Clean, modern chat interface
• Dark theme with X branding
• Clear visual hierarchy
• Intuitive navigation

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.

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:

• Free Tier: Limited access to basic features
• Premium ($16/month): Full access to all features
• Best For: X ecosystem users and power users
• Alternative: Free AI assistants available

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.

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:

• Familiar chat-based interface
• Straightforward onboarding
• Unified interaction system
• Seamless X platform integration

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.

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.

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:

• Standard industry security protocols
• Appropriate permission requirements
• Basic privacy controls
• Data encryption in transit

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.

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.
