Google is bringing an ‘Agent Mode’ to the Gemini app

Google is bringing an “Agent Mode” to the Gemini app and making some updates to its Project Mariner tool, CEO Sundar Pichai announced at Google I/O 2025.

Project Mariner, Google’s AI agent tool that can search the web for you, can now oversee up to 10 simultaneous tasks, Pichai said. 

Pichai also shared details on a feature called Teach and Repeat.  “This is where you can show your task once, and it learns a plan for similar tasks in the future.” Project Mariner will be available “more broadly” this summer, he said.

With Agent Mode in the Gemini app, you’ll be able to give it a task to complete and the tool will go off and do it on your behalf, like with other AI agents. Pichai discussed an example of two people looking for an apartment in Austin, Texas. He said that the agent can find listings from sites like Zillow and use Project Mariner when needed to adjust specific filters. 

An “experimental” version of Agent Mode will be “coming soon” for subscribers, Pichai said.
