Google has announced the rollout of Project Mariner, its experimental AI agent that navigates websites and performs tasks, to a wider audience. The company has made significant updates to enhance the capabilities of Project Mariner, allowing it to multitask and handle multiple activities at once.
### Access for Subscribers
U.S. subscribers to Google’s AI Ultra plan can now access Project Mariner for $249.99 per month, with plans to expand to more countries in the near future. Additionally, Google is integrating Project Mariner’s functions with the Gemini API and Vertex AI, enabling developers to create applications powered by the AI agent.
### Redefining User Experience
First introduced in late 2024, Project Mariner marks Google’s ambitious initiative to transform user interactions with the internet through AI agents. Users can now delegate tasks such as purchasing tickets or shopping online to Project Mariner, eliminating the need to visit individual websites.

### Enhancements and Competition
Google’s Project Mariner competes with other web-browsing AI agents like OpenAI’s Operator and Amazon’s Nova Act. Feedback from early testers has driven improvements in Project Mariner’s performance, with the agent now running on virtual machines in the cloud to handle multiple tasks simultaneously.
### Future Developments
In the upcoming months, users will have access to Project Mariner in AI Mode, offering an AI-powered search experience within Google Search Labs. Furthermore, Google has introduced a preview of “Agent Mode,” combining web browsing with research features and integrations, set to launch for Ultra subscribers on desktop.
Google’s initiatives with Project Mariner, Agent Mode, and AI Mode signal a shift in how users navigate the web and how businesses engage with customers online. These web-browsing agents hold significant implications for the digital economy, and Google is poised to introduce these agents to the world.
