AI Chatbots in Sinhala and Tamil for Sri Lankan Businesses (WhatsApp, Website and Voice)
Modern AI models can understand and reply in Sinhala, Tamil and English, including mixed "Singlish" and transliterated messages, which makes WhatsApp, website and phone assistants practical for Sri Lankan businesses. A good chatbot is trained on your own products, prices and policies, hands over to a human when unsure, and connects to your bookings or orders. Calcus AI builds these chatbots and voice assistants for businesses across Sri Lanka.

- Answering questions about products, prices, opening hours and delivery 24/7
- Taking orders, bookings and appointments, and sending confirmations
- Qualifying leads and passing them to your sales team with a summary
- Order status and delivery tracking
