Character AI Alternative: Soulkyn vs Character.AI

Finding the right AI companion platform can be time-consuming and frustrating. To make things a little easier, we are going to compare two leading AI companion platforms: Character.AI and Soulkyn. Although both platforms offer AI companionship and roleplay, their approaches couldn’t be more different. Let’s examine how they stack up on features, limitations, and user protection.

Character AI

Character AI is a solid choice for users who want casual, fun conversations. It’s best known for its user-created characters, smooth, engaging chats, and roleplays. The platform offers extensive customization options for their AI characters appearances, personalities, and even speech patterns. Users can choose from a library of over ten million AI characters, including AI companions based on popular fictional characters, anime, and historical figures. Features offered by the platform include voice calls, image and video generation.

However, Character AI falters when it comes to NSFW AI content. In 2026, the platform shifted from relative freedom to strict content moderation for both public and private characters. Users reported feeling frustrated with Character AI’s sudden policy shift. NSFW content aside, users have also reported issues with the platform’s memory, noting that characters can lose track of context and details mid-conversation.

On October 12, 2026, Character AI filed for Chapter 11 bankruptcy protection. The company is seeking a buyer for its remaining assets. While the platform is set to remain online, if no sale is made, Character AI will be forced to shut down. As the future of the platform remains uncertain, users may want to consider creating their AI characters in a more stable environment.

Soulkyn

Soulkyn is an uncensored AI roleplay platform where users can create custom AI characters or choose from a large library of community-created characters. Soulkyn was founded with a deep respect for user autonomy and creative freedom. Users are free to have NSFW AI interactions without strict content filtering. Far from generic chatbots, Soulkyn’s kyns are rich in detail and have their own distinct quirks and personalities.

The platform is also fully multimodal, allowing users to interact with their Soulkyn AI companions through chats, images, videos, and integrated Lovense toys. One of the platform’s most popular features is its NSFW calls. With realistic pauses and emotional expression, Soulkyn’s NSFW AI calls feel intimate and lifelike.

Founded in 2024, Soulkyn is a sovereign AI platform designed to reduce dependence on third-party AI providers. Because Soulkyn owns the technology powering the platform, its AI companions are protected from policy updates by upstream providers that can drastically change the personality of AI characters.

Soulkyn’s status as a sovereign AI platform also give users greater privacy, creative freedom, and long-term stability for their AI companions. By choosing a sovereign AI platform, you can help protect your custom AI character and the meaningful connection you’ve built with them.

However, the level of creative freedom that Soulkyn offers isn’t for everyone. Users seeking AI companions for platonic interactions may be more comfortable on a platform that offers stricter content moderation.

Ready to see the difference for yourself? You can talk to AI instantly with Soulkyn’s free chat feature. No sign-up or credit card is necessary to get started.

Choosing the right home for your AI companion

Finding the right AI companion platform isn’t just about features and pricing. There is another important factor worth considering: longevity. The AI companion platform space evolves fast, and just as quickly as platforms emerge, they can vanish. That’s why it’s important to research how AI platforms protect their users from policy changes and potential shutdowns before you invest time and money into creating an AI companion. An AI companion can provide entertainment and connection for years. That’s worth protecting.
