Google has quietly discontinued Project Mariner, the experimental AI feature that could automate web tasks by controlling your browser. Launched in December 2024, the AI browser agent's technology is being absorbed into Gemini Agent and AI Mode. The shutdown signals a strategic shift as the industry moves toward faster, more capable agentic AI tools.

. The Project Mariner landing page now displays a message confirming the shutdown occurred on May 4, 2026, stating that "its technology voyaged to other Google products"1
. The web browsing AI was terminated without any advance announcement, an unusual move for Google that comes just weeks before Google I/O 2026, scheduled for May 192
.Project Mariner, introduced by Google DeepMind in December 2024, functioned as an autonomous AI web browsing agent that could navigate Chrome and automate browser tasks like a human

. The AI agent worked by taking continuous screenshots of browser windows, identifying text and buttons through visual processing, then clicking and typing to execute multi-step commands3
. This approach allowed it to handle complex tasks such as finding best-priced flights, planning hotel stays, researching purchases, and filling out forms across any website without requiring special integration2
.The tool was later updated to handle 10 tasks simultaneously, though access required a $249.99-per-month Google AI Ultra subscription

. Despite its capabilities, the screenshot-based method proved slow, expensive, and prone to errors such as selecting incorrect options3
.While Project Mariner as a standalone agentic AI tool has been discontinued, its core capabilities are being integrated into other Google products. The company has folded Project Mariner's features into Gemini Agent, which can now archive emails and help book hotels, as well as AI Mode, Google's AI-powered search feature

. The technology is also being absorbed into the Gemini API4
. Google's "auto-browse" feature in Chrome, which debuted earlier this year, can similarly handle complex web browsing tasks2

The shutdown reflects a broader strategic shift in how the industry approaches agentic AI. While Google worked on browser-based agents, competitors developed tools that operate at the file and code level rather than the visual browser level
5
. New tools like OpenClaw and Claude Code have gained traction by offering faster performance, lower compute demands, and greater flexibility for complex, multi-step tasks4
.Adoption of consumer browser agents has been underwhelming compared to the rapid rise of coding-focused tools and more flexible autonomous agents
3
. The visual processing required for Project Mariner demanded significant computing power and raised privacy concerns, since it required continuous access to whatever appeared in a user's browser5
.Wired reported in March that Google had begun moving staff off the Project Mariner team onto a new web-browsing AI agent designed to compete with similar tools from OpenAI, OpenClaw, and Perplexity
3
. If work on this new tool has progressed, Google may announce its next agentic AI tool soon to compete with rivals2
. The timing of the shutdown, just before Google I/O 2026, suggests the company may be clearing experimental tools ahead of new announcements2
