• Scraping the company's website at set intervals to update the knowledgebase.
• Integrating with GoHighLevel SMS to provide users with timely and accurate information.
• Utilizing AI to interpret user queries and fetch relevant information from the updated knowledgebase.

• An active n8n instance (self-hosted or cloud).
• A valid OpenAI API key (or any compatible AI model).
• A Bright Data account with Web Unlocker setup.
• A GoHighLevel SMS LeadConnector account.
• A GoHighLevel Marketplace App configured with the necessary scopes.
• Installed n8n-nodes-brightdata community node for Bright Data integration (if self-hosted).
