Google is shutting down its experimental AI browser agent that could browse the web, fill forms, search listings, and book trips for you.
The tool relied on screenshots and visual recognition to interact with websites like a human.
Google isn’t abandoning the tech entirely, as many of the tool’s features are being folded into the Gemini API and Gemini Agent.
Google is reportedly pulling the plug on Project Mariner, the experimental AI browser agent it once positioned as the future of how people interact with the web.
If you didn’t follow the buzz, Project Mariner (introduced during I/O 2025) was Google DeepMind’s effort to create an AI that could use the internet much like a person. However, in March, there were signs that the project was going to bite the dust after Google moved staffers off the Project Mariner team, as reported by Wired‘s Maxwell Zeff.
