─── AI / BETA FEATURES ─────────────────────────────

🤖 RAG Smart Replies Upload your product catalog, FAQ, or pricing sheet as PDF/TXT/CSV. When a customer messages you, Grok-3 reads your documents and replies accurately — automatically. No human needed.

📅 Campaign Scheduler Queue campaigns to send at any future date and time. Powered by BullMQ — reliable even after server restarts.

📧 Email Fallback When a WhatsApp message fails to deliver, the system automatically re-sends it via email using Resend. Zero missed leads.

🌍 Multi-Language Auto-Replies Detects the language of every incoming message and responds in the same language — Hindi, Marathi, Tamil, Gujarati, Telugu, and more.
