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.

Questions & Answers

As answered by people managing Sparkles AI and Hypervector.

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.
