No NSFW content whatsoever. Character.AI has strict content filters that block any romantic, sexual, or violent content. This makes it safe for all ages but unsuitable if you want adult interactions. The filters cannot be bypassed.
Replika
Limited NSFW with Pro. Replika Pro unlocks "Romantic Partner" mode with intimate conversations and ERP (erotic roleplay). However, it's more restrained than dedicated NSFW platforms. Good for light romantic content, not explicit.
