Instead of writing code to click buttons or parse HTML, you describe the task and TinyFish Web Agent figures out how to do it. ## The Mental Model Think of TinyFish Web Agent as a capable assistant sitting in front of a browser. It can see what's on the screen, click, type, scroll, and navigate, but it needs clear instructions. **What it can do:** * See exactly what you would see on the screen * Click, type, scroll, and navigate * Wait for dynamic content to load * Follow instructions precisely * Return structured data * Navigate multi-page PDFs and extract content * Remember information across workflow steps * Parse natural language into form fields **What it cannot do:** * Read your mind about what you meant * Guess what to do when something unexpected happens * Know your business context unless you tell it * Decide on output format without explicit instructions Your job is to remove ambiguity. The more explicit your goal, the higher your success rate. *** ## Quick Examples **Data extraction:** ``` Extract product name, price, and stock status. Return as JSON. ``` **Form filling:** ``` Fill the contact form with name "John Doe" and email "john@example.com", then click Submit. ``` **Multi-step workflow:** ``` 1. Login with email "user@example.com" and password "pass123" 2. Navigate to the dashboard 3. Extract account balance ``` *** ## Learn More Learn how to write goals that succeed on the first try with our Goal Prompting Guide.
