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。

主要功能

  • 独立地进行网页导航和点击
  • 自然语言任务指令
  • Chrome插件接口
  • 逐步行动的透明度
  • 在关键操作前发出确认提示
  • 基于Google的Gemini模型

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.
