Snapshot Facts About Grok AI

How to Access Grok AI: Website, App, and Login

Grok AI can be accessed through several channels, each with slightly different features and availability. The primary entry point is the standalone website at grok.com, where users can sign up for a free account or log in with an existing X (formerly Twitter) account. According to a 2025 usage guide by Voiceflow, you can use Grok directly at grok.com without needing an X account, though some features may be limited.

Grok AI Website

The official website is grok.com. It provides a full chat interface with access to most features, including real-time search, image generation, and Grok Studio. The xAI official page at x.ai also offers a landing page with links to the app and API.

Mobile Apps: iOS and Android

Dedicated apps are available on the Apple App Store and Google Play Store. However, feature availability can vary by platform. For example, Grok Vision — which lets users point their phone camera at objects and ask questions — launched first on iOS and was not yet available on Android at the time of the TechCrunch report in April 2025. The apps are listed as “Grok AI” and are developed by xAI.

Login and APK

To log in, visit grok.com or open the app and sign in with your X account. If you don’t have one, you can create a free X account. For Android users, the official app is available on the Google Play Store. While APK files can be downloaded from third-party sites, the official store is recommended for security. The app is also available on the Apple App Store.

Is Grok AI Free? Features and Limitations

Grok AI offers a free tier that allows limited usage. According to multiple sources, including Voiceflow and BuiltIn, all X users can access Grok with usage caps. For heavier usage and advanced capabilities, paid plans are required. These include X Premium+, SuperGrok, and SuperGrok Heavy, though pricing details vary across sources.

Free Tier

Free users can send a limited number of messages per day, access real-time web search, and use basic image generation. The free tier is available on grok.com and the mobile apps. Voice mode and Grok Studio are also available to free users, according to a 2025 report by Bix Academy.

Paid Plans

X Premium+ subscribers get priority access to Grok 4 and extended usage limits. SuperGrok is a separate subscription that offers additional features like Grok Vision and image editing. The exact pricing for these plans is not consistently reported, and some sources list different tiers and prices.

Image Generation and Video

Grok can generate images using the Flux model, and image editing was added in 2025. Video generation is not yet publicly available, but xAI teased a feature called Grok Imagine, which was released on July 28, 2025, for creating six-second animated audiovisual clips from text prompts. This feature is still in early stages.

What Does “Unhinged” Mode Mean?

Unhinged mode is a personality setting that makes Grok less filtered, more humorous, and willing to engage in controversial topics. It can be toggled in settings. The feature is part of Grok’s “rebellious” persona, but exact moderation policies remain unclear.

Grok AI vs Alternatives: How Does It Compare?

Grok AI competes directly with ChatGPT, Claude, Gemini, and Perplexity AI. Its main differentiator is real-time access to X (Twitter) data and its “unhinged” personality, which appeals to users seeking a less censored conversational AI. However, its free tier is more limited than some competitors, and its reliance on X Premium subscription may affect adoption.
