Google’s Gemini AI app now has more than 400 million monthly active users, CEO Sundar Pichai said during a press briefing ahead of Google I/O 2025.
Google’s AI chatbot app is now approaching a similar scale to OpenAI’s ChatGPT app. According to recent court filings, Google estimated in March that ChatGPT had around 600 million MAUs, whereas Gemini only had 350 million MAUs.
The rise of ChatGPT presents a significant threat to Google’s Search business, offering users a new, more interactive way to access information on the web. The Gemini app is Google’s most direct challenge to compete with OpenAI in the chatbot era, and it seems to be working out so far — the Gemini app seems to be successfully pulling users away from ChatGPT.
In recent months, Google has shaken up the ranks behind Gemini. The Google leader behind the viral NotebookLM app, Josh Woodward, is now in charge of Gemini, part of an effort to generate some buzz around Google’s AI chatbot.
Of course, the Gemini app is just one way Google puts its AI in front of users. Pichai also said during the call that Google’s AI overviews now reach more than 1.5 billion users every month. The company also announced during Google I/O 2025 that it’s putting AI mode in front of more users, as Google tries to update Search with more conversational experiences powered by generative AI.
While OpenAI and Google have the most widely used AI chatbot apps, Meta is trying to break into the space as well. CEO Mark Zuckerberg recently said Meta’s AI products have more than a billion monthly active users across Facebook, Instagram, and WhatsApp, and it recently launched an AI chatbot app to compete with ChatGPT and Gemini.
While the ChatGPT app was the only game in town a few years ago, it’s now got a healthy dose of competition from Big Tech’s largest players.
