a Couple Questions

[eyupcanbilgin]

Hello everyone, I'm seeking assistance from individuals who have extensive knowledge and experience with Wiki.js. I have a few technical questions regarding scaling, permissions, gamification, and particularly about integrating an AI-supported chatbot.

Is there any user-based pricing for Wiki.js when scaling up in user count? Specifically, does hosting on our own infrastructure affect costs directly through Wiki.js, or are there indirect costs associated with scalability?
Does Wiki.js support role-based access control for managing user logins? I am interested in setting different permissions based on user roles. Can you provide details on how to configure these settings within Wiki.js?
I'm looking to implement a content creator league within Wiki.js, where contributors can be ranked based on their input. Does Wiki.js offer any native features for gamification, or would this require custom development or integration with third-party services?
Regarding the integration of an AI-supported chatbot, does Wiki.js support adding API-based extensions for such functionalities? How flexible is the platform in terms of integrating advanced technologies like AI chatbots?
