Grok is a generative AI chatbot built by xAI, the artificial intelligence company founded by Elon Musk. It uses advanced large‑language models (LLMs) such as Grok 3 and Grok 4 to deliver helpful conversational responses across a range of tasks — from answering general knowledge questions and explaining concepts to assisting with coding, writing, summarization, and reasoning. Users can interact with Grok via its web interface at Grok.com, mobile apps for iOS and Android, and integrations with platforms like X (formerly Twitter). It aims to combine broad general knowledge with real‑time data access and a distinctive personality in its responses.
