Soulkyn is an adult-oriented AI companion platform that lets users create custom AI girlfriends, boyfriends, or original characters ("Kyns") and engage them in unfiltered text roleplay. The product emphasizes long-term memory so companions remember past conversations and evolve over time, alongside voice chat and on-demand image and video generation tied to the conversation. Users can also browse a large library of community-created characters spanning romance, fantasy, and RPG-style worlds. Soulkyn is explicitly NSFW: it permits uncensored adult conversations behind age gating. It is offered primarily as a web app, with subscription tiers scaling from chat-only access to unlimited multimedia generation. The platform reports surpassing one million registered users. Funding, ownership, and headquarters are not publicly disclosed.
