How do I make a website for chatbots? (Mostly roleplay)

Due to everyone leaving character ai I kind of want to make a website like character but without the filter and more stuff (because I’m extra)

despite taking a coding class for years I am really dumb and don’t know what to do

google was not helpful

(for clarification I have older friends who would do the none filtered stuff for me since I don’t like gore BUT there would be a button to turn off violence and nsfw plus an age check so minors don’t see nsfw)
