πŸ”„ Conversation Flow

Example: Fill Form with Missing Data

1. User: "Fill this form"
   ↓
2. ConversationalAgent.sendMessage()
   ↓
3. IntentAnalyzer β†’ Type: automation, Goal: "Fill form"
   ↓
4. DOMAnalyzer β†’ Found form with name, email, message (all required)
   ↓
5. Agent checks data β†’ Missing all 3 fields
   ↓
6. QuestionGenerator (AI) β†’ "I can see a contact form. What's your name, email, and message?"
   ↓
7. User: "John, john@test.com, Hello"
   ↓
8. IntentAnalyzer.extractData() (AI) β†’ {name: "John", email: "john@test.com", message: "Hello"}
   ↓
9. Agent checks data β†’ Have all required fields now
   ↓
10. QuestionGenerator.generateConfirmation() (AI) β†’ "I'll fill... Should I proceed?"
    ↓
11. User: "yes"
    ↓
12. AgentPlanner.generatePlan() (AI) β†’ 3 steps (type name, type email, type message)
    ↓
13. ChromeExecutor β†’ Executes each step
    ↓
14. Progress updates β†’ "βœ… Typed John into name field", etc.
    ↓
15. Completion β†’ "βœ… Automation completed successfully!"

βœ… Smart DOM Analysis

  • Detects forms automatically
  • Identifies required fields
  • Checks if actions are possible
  • Handles various input types

βœ… Conversational Multi-Turn Dialogue

  • Asks clarifying questions
  • Remembers context
  • Extracts data from responses
  • Confirms before executing

  • Always confirms actions (configurable)
  • Never auto-submits without asking
  • Respects "no" responses
  • Clear progress reporting

βœ… AI-Powered Everything

  • Intent analysis β†’ AI
  • Data extraction β†’ AI
  • Question generation β†’ AI
  • Plan generation β†’ AI
  • All using OpenRouter API

πŸŽ“ How to Use (For Developers)

Simple Integration

import { ConversationalAgent, AgentConfig } from 'bytechat-browser-agent';

const agent = new ConversationalAgent({
  openrouterKey: 'sk-or-v1-...',
  model: 'openai/gpt-4o-mini',
  onMessage: (msg) => {
    console.log(msg.content);  // Display to user
  }
});

// User sends message
await agent.sendMessage("Fill this form with name=John");

// Agent handles everything:
// 1. Analyzes intent
// 2. Checks DOM
// 3. Asks for missing data OR confirms
// 4. Executes automation
// 5. Reports progress

That's it! The agent is completely autonomous.


πŸ”§ Configuration Options

interface AgentConfig {
  openrouterKey: string;      // Required
  model?: string;             // Default: 'openai/gpt-4o-mini'
  onMessage: (msg: AgentMessage) => void;   // Required
  onProgress?: (progress: AgentProgress) => void;
  onError?: (error: AgentError) => void;
  confirmActions?: boolean;   // Default: true
  autoSubmitForms?: boolean;  // Default: false
}

πŸ“ˆ Performance

Typical Response Times

  • Intent analysis: 0.5-2s (AI call)
  • DOM analysis: 100-300ms (page scan)
  • Question generation: 0.5-1s (AI call)
  • Plan generation: 1-3s (AI call)
  • Execution: 300-500ms per step

Total Time

  • Simple form fill: 5-8 seconds (with all data)
  • With questions: 10-15 seconds (one round of Q&A)
