Google recently launched its first actionable AI agent on the web, named Project Mariner. Powered by Gemini, this agent can control your Chrome browser, move the cursor on your mobile screen, click buttons, and fill out forms, allowing it to use and browse websites like a human. Project Mariner can perform tasks such as 'create a shopping cart from this list at the grocery store.' The agent navigates to the grocery store's website, searches for, and adds items.
