On May 19, 2026, Google published its Search announcements from I/O 2026.

What Google announced

  • Intelligent search box. Described as the first major upgrade in more than 25 years, with AI-powered suggestions and multimodal input: text, images, files, videos and Chrome tabs.
  • Information agents. AI agents that monitor the web around the clock for updates matching a person’s criteria. Available to Google AI Pro and Ultra subscribers this summer.
  • Agentic booking. Expanded to local experiences, services and some categories such as home repair, with a US rollout this summer.
  • Agentic coding. Custom generative interfaces such as dashboards and trackers, due in summer 2026.
  • Personal Intelligence. Expanded to nearly 200 countries and 98 languages, with secure connections to Gmail, Google Photos and Google Calendar.
  • Model. Gemini 3.5 Flash is the default in AI Mode globally.

Google says AI Mode passed one billion monthly users within a year of launch, with queries more than doubling every quarter.

Our read

Two changes affect marketers most. A box that accepts files and images means queries will not always be words you can target. Agents that watch the web and act mean the first audience for a page may be software working for a person. Because most items were scheduled for summer, check which have shipped before making plans, and test how your content is cited in AI Mode answers.
