### Who’s it for
- Users who want an AI assistant directly on WhatsApp.  
- Businesses needing real-time FAQ and support automation.

---

### What it does
- Connects WhatsApp to **Groq’s LLaMA 4** model for AI responses.  
- Uses **SerpAPI** to fetch **real-time search results** from Google.  
- Maintains **context of the last 20 messages** for continuous conversations(you can increase in the AI agent).

### How it works
1. A user sends a message to your WhatsApp number.  
2. The workflow checks if it’s **text** (images can be added later).  
3. Text is sent to the AI Agent, which uses Groq’s LLaMA 4 for responses.  
4. If real-time info is needed, SerpAPI fetches results from Google.  
5. The reply is composed and sent back to the user via WhatsApp.
