- Project Mariner is Google's new artificial intelligence agent designed to automate tasks on the web.
- Allows users to delegate up to ten simultaneous activities across different sites, from shopping to booking.
- Currently available to AI Ultra subscribers in the US, with expansions to other markets coming soon.
- It is integrated with the Gemini and Vertex AI platforms and will collaborate with industry-specific companies on new use cases.

A new agent powered by artificial intelligence is about to change the way we interact with the web. Google has presented Project Mariner, an experimental technology intended to automate tasks on the Internet and operate on web portals without the need for user intervention step by step. With this move, the company definitively joins the race for multitasking intelligent agents, competing with proposals from companies like OpenAI, Amazon, and Anthropic.
Project Mariner is emerging as a digital assistant capable of taking on online navigation and management tasks.This advancement could be a true revolution, as it frees users from daily internet tasks, allowing artificial intelligence to perform end-to-end tasks. All of this, according to Google, is done securely and efficiently.
What exactly is Project Mariner and how does it work?
The essence of Project Mariner is in its ability to perform up to ten tasks simultaneously on the webFor example, a user can ask Mariner to buy tickets for a show, reserve a table at a restaurant, or manage online purchases. The agent navigates pages, fills out forms, and completes transactions just like the user, but without the user having to jump from tab to tab.
To achieve this, Mariner works primarily on virtual machines in the cloud, which provides greater speed and flexibility compared to previous solutions that only worked from the browser. It can also continue working in the background, allowing you to continue using your computer without interruption while the AI takes care of the rest.
Current availability and expansion plans
At present, Project Mariner is available to those who purchase the AI Ultra plan. from Google in the United States, which costs $249,99 per month. Google has already made it clear that access will be progressively extended to more users and developers in other countries in the near future.
This technology is being integrated into key hubs of the Google ecosystem, such as the Gemini and Vertex AI APIThe goal is to enable both ordinary users and developers to incorporate intelligent agents into new applications and services.
Furthermore, Project Mariner will be part of AI Mode, Google's experimental search experience, initially available to those who participate in Search Labs, the company's testing laboratory.
Collaborations, actual uses and planned improvements
To strengthen its proposal, Google has already announced alliances with platforms such as Ticketmaster, StubHub, Resy and VagaroThese collaborations will allow AI to perform automated actions for ticket purchases, restaurant reservations, and other common online workflows, all without the user having to manually navigate multiple sites.
The company has also shown the first steps of the new Agent Modea whirlpool bath, interface that combines assisted navigation methods, improved search y capacity of Integration with other tools in the Google ecosystem. It is expected that those who have the Ultra plan can try this mode from desktop computers soon.
Challenges and the future of automated web browsing
One of Google's ambitions is Minimize the manual interaction required for everyday web operationsHowever, technical challenges remain. So far, both Mariner and its alternatives have shown speed and accuracy limitations in some actions, so evolution will be constant as AI advances.
Integration with Gemini and Vertex AI represents a fundamental step toward an environment where agents not only answer questions, but are also capable of executing complex actions and integrating into business processes.
His arrival represents a paradigm shift in the relationship between the user and the webThe automation and delegation of manual tasks are increasingly becoming an everyday reality, opening up new possibilities for developing innovative services and improving the online experience.
