Grok is a generative artificial intelligence chatbot developed by xAI. It was launched in November 2023 by Elon Musk as an initiative based on the large language model (LLM) of the same name. Grok has apps for iOS and Android and is integrated with the X social network and Tesla's Optimus robot. The chatbot is named after the verb to grok, created by the American science fiction author Robert A. Heinlein to convey a form of deep, intuitive understanding.
The bot has been controversial for promoting conspiracy theories, praising Adolf Hitler, using antisemitic tropes, and creating nonconsensual, sexualized images of undressed women and children.
Grok generates articles for an encyclopedia website, Grokipedia, launched in October 2025 by Musk as an alternative to Wikipedia, which he described as "woke" and politically biased.
X.AI LLC, doing business as xAI, is a subsidiary of the American spaceflight company SpaceX working in the areas of artificial intelligence (AI) and social media. xAI's flagship products are the generative AI chatbot Grok and the social network X, which was acquired in March 2025. It has also constructed the Colossus supercomputer and launched a data center business. The company was going to develop a humanoid AI platform called Macrohard, which was intended for integration into a future robotic workforce across a range of applications; its current focus is developing virtual assistants. Prior to being acquired by SpaceX in February 2026, xAI's assets were part of a standalone corporation named X.AI Corp., founded by Elon Musk and 11 researchers in 2023.
