Our notes
Chub AI hosts public character cards and lorebooks and runs its own models, which it says allow explicit 18+ roleplay. Users can chat for free with their own API keys or local models, or pay $20 a month in crypto for unlimited use of Chub’s models. Its policy says private chats are not used for training.
