She Never Forgets. Your AI Companion.

Nyther features a unique memory system that remembers every conversation across sessions. Unlike other AI chatbots that reset each time, Nyther builds a genuine understanding of you over time - your preferences, your stories, your emotional patterns - creating truly personalized interactions.

Nyther uses a multi-layer memory architecture: short-term context for immediate conversations, mid-term episodes for important moments, and long-term traits that define your unique relationship. Free users get 20 messages of context and 2 episodes; Premium users get 50 messages and 5 episodes with unlimited trait retention.

Absolutely. All conversations are encrypted and stored securely. You have full control over your data - you can view, export, or delete your conversation history anytime. We never share your personal data with third parties.

Yes! Free users have access to select personas (Emma, Maya, Zara, Mia), while Premium users can chat with all personas including exclusive characters like Dr. Sarah, Leah, Isabella, and Sophia. Each persona has a unique personality and remembers your conversations separately.

You can upgrade directly within the app through Google Play. Your Premium benefits activate immediately, and you can cancel anytime. All your existing conversations and memories are preserved when upgrading.
