AI Chat Online - FAQs
Are my conversations private?
Will the AI character stay in role the whole time?
Yes. Characters are designed to maintain their personality consistently throughout the conversation - no random tone shifts, no breaking character mid-chat. The User Profile Card helps the character respond in a way that fits your dynamic specifically.
What if I want to switch between a character and an assistant mid-session?
You can do that within the same platform. Character chats and assistant-type AI characters are both accessible without switching apps or logging in again. Finish your task with the assistant and jump back to your character - your chat history for each stays separate and intact.
