+# Browser component
+
+A component that autonomously navigates web pages and extracts specific content using standard formats or custom selectors.
+
+---
+
+A **Browser** component is usually the downstream of an input component or a search API component that provides URLs, and the upstream of an LLM component for summarization or analysis.
+
+## Scenarios
+
+A **Browser** component is essential when you need the agent workflow to fetch real-time data from external websites, scrape specific dynamic elements, or navigate web pages before passing the extracted content to an LLM.
+
+## Configurations
+
+### Action type
+
+Select the primary operation the browser will perform. For example, selecting **Get page content** instructs the component to retrieve the text and structure of the target webpage.
+
+### URL input
+
+*Mandatory*
+
+Specify the web address the browser should navigate to. This field accepts dynamic variables from upstream components. For instance, you can reference a variable like `{{search_results_url}}` generated by a previous search component.
+
+### Selectors
+
+Define the specific data points to extract from the loaded web page. You can add multiple selectors to extract different pieces of information simultaneously.
+
+- **HTML**: Allows you to extract broad page elements, such as the full HTML of the document.
+- **CSS selector**: Allows you to pinpoint exact data using standard CSS selectors (e.g., `.product-title` or `.product-price`). This is highly useful for targeting specific text blocks, tables, or item attributes within a structured webpage.
+
+### JavaScript enabled
+
+A toggle to determine if the browser should execute JavaScript on the target page. Setting this to **True** is highly recommended for scraping modern websites where content is dynamically rendered after the initial page load.
+
+### Wait for
+
+Configure delay conditions to ensure the page has fully loaded before the component attempts to extract data.
+
+- **Wait for element**: Pauses the extraction until a specific CSS class or ID (e.g., `results-container`) becomes visible on the page.
+- **Input (seconds)**: Imposes a strict time delay (e.g., `5 seconds`) to give the browser ample time to load all assets and execute background scripts.
+
+### Output variables
+
+The **Browser** component provides three distinct outputs that can be referenced by downstream components in the workflow:
+
+- **Full text**: The raw text content extracted from the page or the targeted selectors.
+- **JSON data**: A structured representation of the extracted elements.
+- **Error code**: Captures and outputs any HTTP errors or navigation failures encountered during the process.
