One year since launching in the United States, Google's AI Mode has crossed a billion monthly active users globally. That's a significant milestone, but the more interesting story is what those users are actually doing differently inside it.
Google shared a set of behavioral insights at I/O 2026 that paint a clear picture of how AI search is changing user habits.
How People Are Searching Differently
The most striking data point is query length. The average AI Mode search is three times longer than a traditional Search query, suggesting people are shifting from keyword shorthand to genuine natural-language questions. Volume is up too: AI Mode queries have more than doubled every quarter since launch, and overall queries are at an all-time high — something Google credits directly to AI Mode's presence.
Voice and image inputs are also growing fast. More than one in six US searches now use voice or images, with image searches growing by more than 40% month-over-month. That's a significant indicator that people are treating Search less like a text box and more like a conversational interface.
Planning and Decision-Making Are the Breakout Use Cases
Trends data shows that planning-related queries in AI Mode grew 80% faster than AI Mode queries overall in the past six months. Brainstorming queries — searches framed around ideas, options, and decisions rather than specific lookups — grew 30% faster than the overall AI Mode query mix since launch.
Searches starting with phrases like “where to,” “where should I,” and “ideas for” are growing, suggesting AI Mode is becoming a genuine decision-making tool rather than just a faster way to look things up. The data indicates people are asking the questions they actually have, not the stripped-down keyword versions they'd previously settled for.
What This Means for Search
For all the noise about AI threatening traditional search, Google's own numbers tell a different story: more queries, longer queries, more modalities. AI Mode isn't cannibalizing search so much as expanding what people think search is for. Whether that holds long-term is another question, but one year in, the trajectory is upward in every direction that matters to Google.
