  • Grok now nears 20 million monthly active users after a roughly 40% jump following the July release of Grok 4, placing fourth on the web and 23rd on mobile.
  • Google appears with four distinct products for the first time, as AI Studio enters the web top 10, NotebookLM lands at No. 13, and Google Labs ranks No. 39.
  • DeepSeek usage has fallen sharply, down about 22% from its mobile peak and more than 40% on the web since February, while Perplexity and Claude continue to grow.
