Soulkyn AI is an AI companion platform built around uncensored, morally-neutral interaction across web and mobile. Users can create deeply customizable companions, adjusting appearance, voice tones, backstories, behaviors and quirks, with NSFW elements fully tailorable within user-set boundaries. The experience spans conversational chat, roleplay with dynamic state tracking (location, clothing, narrator mode), image sharing and voice or audio chat.
What most distinguishes Soulkyn is its infrastructure stance. The company states it owns its entire technology stack, including the models, infrastructure and safety systems, and explicitly does not rent AI from providers like OpenAI or Anthropic. Its team frames this as meaning the platform cannot be shut down by a third-party policy change and can offer creative freedom that API-dependent competitors cannot, a positioning summarized in its own writing as a companion platform that can't be shut down.
The product is tiered by model capability. The freemium plan provides unlimited basic chat on an 8B model with basic memory and no restrictions. Premium upgrades to an unlimited 70B model with superior intelligence, complex dynamic outputs, memory control, image sharing and voice chat. The deluxe tier adds unlimited contextual image generation, group chats with up to three AIs, linked personas and enhanced roleplay with hyperparameter customization.
Soulkyn is the work of a small team. Reporting describes two founders building the platform over roughly 20 months, with a developer known as Nyx central to its engineering. As a bootstrapped, independent operation it discloses no external funding or investors. Pricing is freemium with paid plans starting around $13.96 and a deluxe plan reported near €49.90 per month.
For users prioritizing creative freedom, persistence and independence from third-party model policies, Soulkyn's self-owned stack and deep customization are its core selling points, balanced against premium feature costs that reviewers note run relatively high.
