Sparkles is a free AI girlfriend app where you create your own companion โ€” realistic or anime โ€” and build a real relationship with her, not just a chatbot you reopen.

What makes Sparkles different

  • Persistent memory โ€” she remembers your story across sessions, so the relationship grows instead of resetting.
  • She texts first โ€” proactive messages keep her present in your day.
  • Voice calls โ€” actually talk to her, not just text.
  • Image & video generation โ€” a consistent face, on demand.
  • Uncensored chat โ€” natural adult conversations between consenting adults, no filter cutting the moment.
  • Free to start โ€” daily free credits, no card required.

Built for people leaving other apps

If your companion on Character.AI, Replika, Candy.ai or Janitor AI keeps forgetting you, hits a filter, or waits passively, Sparkles fixes exactly that. Create her in minutes, share your story once, and it sticks.

Sparkles AI features and specs

  • Persistent Long-Term Memory
    Sparkles remembers your conversations, the details you share, and your history together across sessions. Your companion stays consistent and the relationship deepens over time, instead of resetting like most AI chatbots.
  • Proactive Messaging
    Your companion reaches out first with spontaneous messages, picking up an earlier thread or simply checking in. She feels present in your day rather than waiting passively for you to open the app.
  • Voice Calls
    Beyond text and voice clips, Sparkles supports real-time voice calls, so you can actually talk to your companion for a more natural, immersive connection.
  • Image & Video Generation
    Generate consistent images and videos of your AI girlfriend on demand. She keeps the same face and look across pictures, rather than becoming a different character each time.
  • Uncensored Adult Chat
    Built for natural, unfiltered conversations between consenting adults in fiction. Romantic and intimate moments flow without a content filter cutting them off mid-sentence.
  • Full Character Creation Studio
    Shape your companion's appearance, personality, voice, and backstory from scratch, realistic or anime, creating a partner tailored exactly to your preferences.
  • Free to Start
    Free daily credits and no card required to begin, so you can experience the chat, memory, and personality before paying for anything.

Nullstack features and specs

  • Full-Stack Capabilities
    Nullstack allows for the development of both client-side and server-side functionalities within a single project, providing a more unified development process.
  • Seamless SSR
    It offers built-in support for server-side rendering, improving performance and SEO without the need for complex configurations.
  • Zero tooling
    Nullstack provides a setup that requires minimal configuration and does not depend heavily on additional tools, simplifying the development workflow.
  • Component-based Architecture
    Promotes the use of components, encouraging modularity and reusability of code, which can improve maintainability and scalability of applications.
  • Hot Module Replacement
    Supports HMR, allowing developers to see immediate changes in their applications without refreshing the entire page, improving development efficiency.

Possible disadvantages of Nullstack

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

Questions & Answers

As answered by people managing Sparkles AI and Nullstack.

What makes your product unique?

Sparkles AI's answer

Sparkles treats your AI girlfriend as a real, ongoing relationship rather than a disposable chatbot. It combines persistent long-term memory (she remembers your story across sessions), proactive messages (she texts you first), real voice calls, and consistent image and video generation, all with uncensored adult chat. Most AI companions do one of these well; Sparkles brings them together so the companion actually feels present.

Why should a person choose your product over its competitors?

Sparkles AI's answer

Sparkles fixes the three things people complain about most elsewhere: companions that forget you, filters that cut off intimate moments, and apps that wait passively instead of reaching out. Versus image-first apps like Candy.ai, OurDream or DreamGF, Sparkles centers the relationship, not just the gallery. Versus Character.AI or Replika, it allows uncensored adult chat and keeps deep memory. And it's free to start, so you can judge it before paying.
