ChatGPT Remains Most Popular AI Chatbot, But Competitors See Their Audiences Grow, Too

The OpenAI ChatGPT artificial intelligence chatbot remains the most popular service of this type in the world. But competing platforms are also actively increasing their audience, according to statistics from analytics companies SimilarWeb and Sensor Tower.

SimilarWeb specializes in assessing website traffic, including web versions of chatbots, and, according to the company, Google Gemini increased its audience by 7.4% in March compared to February — the figure reached 10.9 million visitors per day; Microsoft Copilot increased its audience by 2.1 million in a month to 2.4 million; Anthropic Claude reached 3.3 million visitors in March; the chatbot of Chinese DeepSeek exceeded the mark of 16.5 million users per day — the same result was shown by xAI Grok. ChatGPT had 500 million visitors per day as of the end of March.

The OpenAI platform remains ahead by a huge margin, but there is a serious battle for second place. DeepSeek, which took second place in March, lost 25% of its February audience, xAI Grok showed an increase of almost 800% compared to the previous month, and this is the largest positive dynamics in the ranking, according to SimilarWeb.

The dynamics of visits to mobile chatbot apps is associated with the release of new AI models. During the week of February 24, when Anthropic released Claude 3.7 Sonnet, the audience of the Claude app grew by 21%, according to statistics from Sensor Tower. Two weeks earlier, shortly after the release of Google Gemini 2.0 Flash, the audience of the Gemini app showed a weekly growth of 42%. In addition to the release of updated models, users are also interested in new features of the services: the Canvas function in Gemini, which allows you to run program code; or new features of Claude, which Anthropic is constantly adding.

But OpenAI has no reason to panic here either. As of March, the number of active users of the ChatGPT mobile app was ten times greater than the audience of Gemini and Claude combined.
