# Hallo Zetta > Hallo Zetta is an AI-first WhatsApp CRM for teams. It combines contacts, conversations, and AI-assisted replies in one workspace—automating routine messages from your knowledge base, supporting human handoff, and working in WhatsApp direct chats and groups. Operated by Incredible Zetta in partnership with Ciptadusa (CDS), part of the Zetta CRM family. An AI-first WhatsApp CRM keeps customer chats, team workflows, and AI automation in the channel your customers already use. Hallo Zetta is built for that: publish docs to a knowledge base, let AI handle routine replies, and let staff take over any thread. In WhatsApp groups, the AI only responds when @mentioned or quoted. ## Product - [Homepage](https://hallo.zettacrm.com/): Overview, features, use cases, enterprise capabilities, and FAQ - [Indonesian homepage](https://hallo.zettacrm.com/id/): Bahasa Indonesia version of the landing page - [Book a demo](https://cal.com/hallo-zetta): Schedule a live product walkthrough - [WhatsApp contact](https://wa.me/6285792071380): Message the team on WhatsApp (+62 857-9207-1380) ## How it works 1.
