- Autonomous web navigation and interaction
- Form filling and data extraction
- Set-of-Marks visual annotation
- End-to-end task completion
- Cross-site workflow automation
Technical Stack
- Browsers: Playwright, Puppeteer, Selenium, CDP
- Vision: GPT-4V, Claude Vision, LLaVA, Qwen-VL
- Analysis: DOM parsing, A11y trees, HTML structure
- Annotation: Set-of-Marks, bounding boxes, element highlighting
- Actions: Click, type, scroll, drag, hover, screenshot
- Frameworks: LangChain, AutoGPT, BrowserGym

Perception Modes
1. Text-Based (DOM/A11y)
- HTML DOM parsing
- Accessibility tree extraction
- Faster but may miss visual context
2. Image-Based (Vision)
- Screenshot analysis
- Visual element recognition
- Better for complex UIs
3. Multimodal (Recommended)
- Combined text + visual
- Set-of-Marks annotation
- Best accuracy
Action Space
| Action | Description | Parameters |
|---|---|---|
| click | Click element | target (mark/selector) |
| type | Enter text | target, value |
| scroll | Scroll page | direction (up/down) |
| navigate | Go to URL | url |
| select | Choose option | target, value |
| wait | Wait for element | target, timeout |
| extract | Get data | target, format |
Best Practices
- Annotate Before Acting: Always use Set-of-Marks for clarity
- Verify Actions: Check state after each action
- Handle Failures: Retry with alternative approaches
- Track History: Maintain action history for debugging
- Wait for Stability: Allow pages to load fully
- Respect Rate Limits: Don't overwhelm target sites
Use Cases
- E-commerce automation (price monitoring, checkout)
- Form filling and submission
- Data extraction and scraping
- UI testing and verification
- Web research and aggregation
- Social media automation
Output Format
- Step-by-step action log
- Screenshots at each step
- Success/failure status
- Extracted data (if applicable)
- Performance metrics
- Error diagnostics
