Hello!
I am helping a friend out with a wordpress site. He wants to build a chat bot in WordPress, and I haven't used WordPress before. So I was curious what would be the easiest way forward. When you arrive to the main site there is some information regarding the chat bot, and you can create an account in order to access the chat. We want to store chat data from conversations for the user.
My main questions are:
1. What framework is easiest to use when developing a web app in WordPress? Or should I build the web app outside of WordPress and just use the WordPress API to send data to the web app?
2. Is the WordPress database easy to work with, or should I use a separate database to handle logins and chat history data?
If you have any advice, or resources to get started I would love to hear your thoughts!

I’m no expert but WordPress doesn’t seem like the best tool for the job. Is there a reason you want to use WordPress for this?
