Implementation
The browser automation agent is built using the browser-use library with Nebius AI:How It Works
The agent operates in several phases:Task Understanding
The LLM analyzes the natural language instruction and breaks it down into actionable steps
Element Interaction
Interacts with page elements (search boxes, buttons, dropdowns) to complete the task
Usage
Example Tasks
Here are example tasks you can perform with the browser automation agent:Configuration Options
