ChatGPT has solidified its position as the leading AI platform in terms of user numbers and engagement. It remains the most popular AI tool, largely due to its early impact with GPT-4 and its human-like interaction style. In April 2025, ChatGPT recorded 780 million visits from American users alone, breaking its own traffic records each month this year. It is now ranked as the fifth most used website globally. Over the past year, ChatGPT's daily active user base has grown more than fourfold, with message volume increasing even more significantly. The engineering team has also improved the platform's reliability and speed. ChatGPT's rapid adoption is replacing legacy technologies at an accelerated pace, and it continues to generate innovative hypotheses, maintaining its strong appeal among users.
