Google Unveils Enhanced Project Mariner AI Agent for Delegating Tasks

Google has announced that it’s rolling out its experimental AI agent, Project Mariner, to more users and developers as part of a broader effort to revamp user experience through AI-powered tools. The company says the updated Project Mariner can handle nearly a dozen tasks simultaneously, making it significantly more useful compared to its predecessor.

Available to US subscribers on Google’s new $249.99-per-month AI Ultra plan, Project Mariner allows users to delegate tasks such as purchasing tickets or buying groceries online without visiting third-party websites. The agent works with Google Search and integrates with other apps to enable seamless task completion.

Google says it’s taken feedback from early testers to improve Project Mariner’s capabilities, allowing it to run on virtual machines in the cloud, similar to agents from OpenAI and Amazon. This update enables users to work on other projects while the AI agent completes tasks in the background.

Project Mariner competes with other web-browsing AI agents, but Google’s update has improved its performance compared to earlier versions. The company plans to expand access to Project Mariner in the coming months, including a new feature called AI Mode, which will be available in Search Labs and other platforms soon.

This development has significant implications for the internet economy, with web-browsing agents poised to change how users navigate online and vendors interact with customers. As Google prepares to ship its agentic experiences, it’s clear that Project Mariner is a key part of this effort.
