What is Lisa?
An assistant that knows your business, not just the internet.
Lisa sits on your website or WhatsApp and answers customers the way your best staff member would — in Hindi, Tamil, Hinglish or whatever they type in.
It learns your menu, catalogue, prices and policies from one link, and every reply is checked against those facts before it is sent. When a question needs a person, or Lisa doesn't know, it says so and hands over.
