Simple chat bot for someone that doesn’t code.

So I’ve been looking to make a chat bot that answers messages. Very simple one, just to start the process with my clients. Like

– Greeting

– Explanation of company select a number

1 option

2 option

3 option

And so on, just so that the simple information that most people need is automated. I don’t want to send messages to people that haven’t sent messages to me, I don’t want an IA answering questions, I don’t want any fancy buttons or animations. Just give me a simple and cheap option that doesn’t require that much coding.

edit: I’m from Brazil if that matters.
