At Google I/O 2026, Google presents what it describes as the biggest changes to Google Search in more than 25 years, focusing on how users move between its AI features. The company shows a redesigned search box intended to make it easier to transition between AI Overviews—AI-generated summaries shown at the top of results—and AI Mode, a chatbot-like search experience. Google also discusses expanding the way users interact with AI assistance inside Search, including features framed as always-available “information agents” and additional personalization capabilities. According to reports, Google expands “Personal Intelligence” availability across nearly 200 countries. Google says AI Mode is now powered by Gemini 3.5 Flash and reports that AI Mode has reached one billion monthly users. The new Search interface is presented as part of a broader “next phase” in Google’s AI evolution for Search, with the goal of providing more integrated, conversational help while keeping it connected to standard search results. Google does not change the fundamental idea of searching, but emphasizes tighter integration between AI summaries, chat-based exploration, and interactive tools surfaced from the search experience.
