Grok
Grok is an AI chatbot by xAI, known for its 'rebellious streak' and real-time information access, integrated with the X social network.
Grok is a generative AI chatbot developed by xAI, founded by Elon Musk. It is designed to answer questions, generate content including text, images, and video, and engage in conversations with a distinctive, often witty and sarcastic, personality. It leverages real-time data from the X social network and the web, and is accessible via a standalone website, mobile apps, and through X subscriptions.
Grok achieved notable market penetration with 17.8% U.S. chatbot market share and strong traffic (314M monthly), backed by massive funding ($42B) from xAI. However, the declining usership between March-April 2026 and fall to fifth place among chatbots, combined with limited free tier access, prevents it from reaching top-tier status.
