24/7 WhatsApp AI Support Bot with Google Docs Integration

Transform your WhatsApp Business into an intelligent 24/7 customer support powerhouse that automatically answers questions using your company's Google Docs knowledge base. This smart AI assistant reads your internal documents in real-time to provide accurate, contextual responses to customer inquiries without any manual intervention.

What this workflow does

When customers send free-form questions to your WhatsApp Business number like "What are the gym rules?" or "Are you open today?", the bot instantly retrieves content from your designated Google Doc containing policies, schedules, or FAQ information. It intelligently merges the document content with today's date and the customer's specific question to create a custom AI prompt. Your chosen AI model (ChatGPT/OpenAI or Gemini) then generates natural, helpful responses sent directly back through WhatsApp. All conversations are automatically logged to Google Sheets for comprehensive reporting and audit trails.

The AI assistant features advanced date intelligence — if your Google Doc states "Closed May 25 for 30 days," it will automatically calculate and respond "We're currently closed until June 24" based on today's date.
