Built a 24/7 WhatsApp AI assistant for Simana Dental Clinic in Dhaka that handles patient inquiries automatically — no human needed. Patients message the clinic on WhatsApp and get instant, accurate replies about services, pricing, working hours, appointments and more. The bot is trained on clinic-specific information and knows when to refer patients to call directly. Built using n8n, Grok AI, and the WhatsApp Business API.
