FunFun AI review
FunFun AI builds its companion experience around chat and pictures. Its FAQ describes ways to shape a character, and its terms give more detail about what private chat means on the service.
Building a companion around the chat
The public FAQ lists personality, interests and conversation style among the settings. It also describes companions that can send pictures. The terms say chats and prompts sit inside the private account and explain that a moderation system can review content for policy compliance.
Private conversation or public character
SpicyChat has published controls for who can open a character and who can see its definition. That is useful if you want to build something to share. FunFun’s terms address a different question by explaining how inputs in a private conversation can still be subject to moderation.
Anabel’s take
I'd start with a character whose conversation style I can describe in a sentence. If I’m mostly interested in writing and sharing a detailed character sheet, I'd choose the service with documented controls for the sheet itself.
