AI Agent Web Automation Browser Extension Research Preview Google DeepMind Gemini Productivity

1 / 4

概览

Project Mariner 是 Google DeepMind 的实验性网页浏览 AI 代理，能够理解屏幕内容并在浏览器中执行相应动作，为用户完成各类任务。它基于 Gemini，能够将自然语言目标转化为一系列点击、滚动、表单填写以及跨实时网站的导航步骤。该代理设计用于多步骤工作流程，例如研究产品、收集信息、填写表单或组装购物车。它在 Chrome 扩展中运行，并让用户始终了解进程，展示其推理过程并在执行诸如购买等敏感操作前请求确认。作为研究原型，Mariner 正在与一小部分受信任用户进行测试，同时 Google 正在研究安全性、可靠性以及在开放网络上自主运行的代理的更广泛影响。

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on autonomous web navigation and clicking, and automates tedious multi-step browser tasks caught me off guard. Can be slow on complex pages is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Years in this space

I've evaluated a lot of these over the years. What stands out here is step-by-step action transparency — handled better than most — and powered by Gemini's reasoning capabilities. Worth the time if this is your use case.

Compared a few options

Evaluated this against two competitors. Where it wins: built on Google's Gemini model and powered by Gemini's reasoning capabilities. Where it lags: may struggle with dynamic or unusual site layouts. On balance the feature set — especially step-by-step action transparency — justifies the 4 stars for our use case.

Years in this space

I've evaluated a lot of these over the years. What stands out here is natural language task instructions — handled better than most — and automates tedious multi-step browser tasks. Requires user supervision for reliability is my one real gripe. Worth the time if this is your use case.

问答

Can Mariner handle complex or dynamic website layouts?

Mariner may be slower on complex pages and can struggle with highly dynamic or unusual site layouts, so it works best on standard, well‑structured web pages and still requires user supervision for reliability.

How does Mariner handle sensitive actions like purchases?

The agent surfaces its reasoning step‑by‑step and asks for your explicit confirmation before performing any key actions such as purchases, keeping you in the loop for safety and reliability.

Asked by Zeynep Aydin · Aug 12, 2025

What browsers does Mariner work with, and how is it installed?

Mariner runs as a Chrome extension, so you need the Google Chrome browser. Install the extension from the provided preview link, and it will appear in your browser toolbar for use.

How can I get access to Project Mariner and is there a cost?

Project Mariner is currently a research prototype available only to a limited group of trusted users. Google has not published public pricing, and access is granted by invitation during the preview phase.
