For years, a browser’s job was simple: help you search, open links, and read webpages. In 2026, that definition is changing. On April 16, Google added an AI Mode shortcut to Chrome on iOS and Android in the U.S., so users could ask longer, more complex questions directly from a new tab. Then, on May 12, Google announced Gemini in Chrome for Android, built on Gemini 3.1, along with “auto browse.” Google says this assistant can summarize the page you are reading, answer questions about it, connect with apps like Calendar, Keep, and Gmail, and even help with chores such as reserving parking or updating an online order. The rollout starts in the U.S. on select Android 12+ devices with at least 4GB of RAM, and sensitive actions still require user confirmation. (blog.google)

This shift is important because the browser is moving from search to delegation. Instead of only showing links, an AI browser tries to understand your goal and do part of the work for you. Google is not alone. Opera announced Opera Neon on May 28, 2025, calling it an “agentic browser” that can search, fill in forms, make bookings, shop, and even create projects such as games, reports, code, or websites with cloud-based agents. Perplexity launched Comet on July 9, 2025, and presented it as a browser for a web where people ask questions everywhere, not only in a search box. Perplexity says Comet can navigate sites, summarize pages, answer questions in context, respond to email, and send calendar invites. (press.opera.com)

What makes this especially interesting is the mobile angle. Google’s recent Chrome updates on Android and iPhone suggest that companies now see the smartphone browser as the next major AI battleground. If these tools work well, they could reduce tab-hopping and save users time. But they also raise a harder question: will people trust a browser that does more than search? Google is emphasizing protections against prompt injection and confirmation before sensitive actions, while Perplexity is also promoting admin controls, telemetry, and data policies for enterprise use. In other words, the future of browsing may depend not only on intelligence, but also on trust. (blog.google)
