Hello @Dina3, I hope you are doing well!
Yes, it is possible to use a chat-bot with Shopify. Chatbots in your business save time. For instance, when used on your website they can provide fast, automated answers to most questions. This will engage your customers and prevent customers from waiting for a day or longer to receive responses as they would have in the past.
You can try the all-in-one Shopify app AiTrillion.
Hope this helps!
