AI in customer service
Cases of AI in customer and patient support: WhatsApp replies, ticket triage, knowledge bases, scheduling and after-sale follow-up. The accounts that worked started small, with well-defined frequent questions and a human ready to step in when the AI does not know. See what each business automated, what it kept with people and a prompt to build the first version of your own support.
14 cases, 8 of them from Brazil, from newest to oldest. The tools cited most here are n8n, OpenAI, and Assistente de IA no WhatsApp. People who show up most in these accounts: developer, clinic manager, and consumer.
