Grokipedia is an AI-generated online encyclopedia operated by the American company xAI, founded by Elon Musk. The site was launched on October 27, 2025. Some entries are generated by Grok, a large language model owned by the same company (xAI), while others were forked from Wikipedia, with some altered and some used nearly verbatim. Articles cannot be directly edited, though logged-in visitors to the encyclopedia can suggest new articles or corrections via a pop-up form, which are reviewed by Grok, and Grok makes autonomous changes to articles.
