Google is completely flipping the script on what a search engine actually does. Instead of just serving up lists of links or summarizing paragraphs of text, Google Search will now build entirely custom, interactive user interfaces and mini-apps on the fly, tailored precisely to your specific questions.
The feature is powered by the combined forces of Google’s new Antigravity agent platform and the agentic coding speed of Gemini 3.5 Flash. Best of all? Google announced it will be available to everyone free of charge.
The Evolution of Search: From Text to Living Interfaces
Instead of forcing users to click through multiple websites to piece together an answer, Search is transforming into a dynamic software engineer. If you ask a highly specific, complex question, Google won’t just look for a webpage that answers it—it will write the code to create an interactive tool or simulation that allows you to explore the answer yourself.
When you look closely at the upcoming layout changes shown above, you can see how Search shifts away from standard rows of text. Depending on your query, it automatically structures independent blocks—assembling real-time comparison tables, custom graphing widgets, or personalized data streams right into the interface.
For ongoing tasks, like planning a wedding or managing a move, Search can code entire custom experiences with Google @Antigravity. Think: mini apps, dashboards or trackers you can come back to again and again. #GoogleIO pic.twitter.com/adoRMqms5o

How It Works Under the Hood
The underlying technology relies on agentic workflows—systems where the AI doesn’t just predict the next word, but operates autonomously as a software engineer to execute multi-step tasks. Google Search leverages the high-velocity execution of Gemini 3.5 Flash alongside the Antigravity orchestration environment to complete a complex pipeline in seconds.
Beyond the One-Off Answer: Custom Mini-Apps
The capabilities of Generative UI go far beyond simple diagrams. Google is enabling searchers to build persistent, functional tools—essentially creating personalized mini-applications within the search engine that you can return to over time.
Custom Fitness & Diet Trackers: You can instruct Search to build a health dashboard that pulls from local data sources, syncs with map routes, and updates based on the daily weather forecast in your neighborhood.
Logistics & Planning Hubs: For long-running, multi-layered tasks like managing a cross-country home relocation or organizing a wedding, Search can assemble dedicated progress trackers that save your state across sessions.
Scientific Simulations: If you are trying to understand complex mechanical physics or astronomical ratios, the engine will spin up a canvas-based sandbox where you can adjust variables (like gravity or velocity friction) to see outcomes in real time.
The Technical Advantage: According to Google DeepMind engineering data, the Gemini 3.5 Flash model underpinning this architecture is engineered specifically for speed, executing agentic coding tasks up to four times faster than previous models. This performance leap is what makes real-time, on-the-fly interface generation usable at consumer scale.
Availability
The initial rollout of basic Generative UI layouts will hit Google Search for all users over the coming summer months entirely free of charge. More advanced, persistent mini-apps powered by the Antigravity platform will begin testing shortly after, launching first for Google AI Pro and Ultra subscribers in the United States before expanding globally.
