Grok 1.2.36 for Android

Grok 1.2.36 is the Android app of the generative AI chatbot from xAI. You type or speak a question and the chatbot answers in plain language, helping with explanations, writing and ideas; the app is free to download, and Grok is also available on the web at grok.com.

What is Grok?

Grok is a chatbot built on a large language model, a type of artificial intelligence trained on huge amounts of text to predict and generate language. It was first announced in November 2023, and the underlying model has since gone through several generations, from Grok 1 in 2024 to Grok 4 in July 2025. In everyday use it behaves much like other AI assistants: you ask it to explain a topic, summarise a text, draft an email, suggest names for a project or think through a problem step by step. The answers can be impressively fluent, but fluency is not the same as accuracy. Like every language model, Grok can state wrong facts with confidence, so it works best as a starting point and a sparring partner rather than as a final authority.

How do I install it?

1. Open Google Play on your phone and search for Grok by xAI; check the developer name before installing.
2. Install the app and sign in with the account you want to use.
3. Grant only the permissions you are comfortable with.
4. Start with a simple question to see how the answers look on your screen.

Key facts

Is it free?

The app is free to download and can be used without paying. Some features may depend on paid plans; check the current terms on the official site, because they change as new models appear.

Is Grok open source?

Partly in history, not in the app. The weights of the early Grok-1 model were published in the xai-org/grok-1 repository under the Apache License 2.0, while the app and the current service are proprietary. Developers can follow changes to the paid API in the xAI release notes.

How do I use it safely?

• Do not paste passwords, ID numbers, medical records or confidential work documents into the chat.
• Check important facts, figures and quotes against reliable sources.
• Treat medical, legal and financial answers as general information, not advice.
• Read the privacy policy and review the app's settings before sharing anything personal.
• Install the app only from Google Play; fake AI apps are common.
