*Chatbase helps companies companies build AI agents that are trained on their data to chat with users and perform tasks. These include integrations with tools like WhatsApp and Slack, advanced analytics that track chat topics and sentiment, a ticketing system to escalate complex queries to a human, and AI actions that allow the chatbot to perform tasks like adding items to a cart or booking meetings on behalf of the user or any action specific to your business.
