**Talk to the people you miss โ€” with an AI that truly understands them.** "wish I could talk to them againโ€ฆ" want is an AI chat app that lets you create personas of the important people in your life and chat with them as if they were really there. Mom, dad, a close friend, a partner, a mentor โ€” any relationship, any personality. You decide who they are. **Personas so real, it feels like them** Beyond just a name and relationship, want lets you set personality traits, speaking style, catchphrases, mood, background, and more. In v1.3.0, we completely redesigned the system prompts so the AI deeply understands relationship dynamics, emotional states, shared history, and even what they used to call you. The result? Conversations that feel warm, familiar, and unmistakably real. **The more you talk, the more it remembers** With the new Long-Term Memory feature, the AI automatically summarizes past conversations and retains what matters. It will naturally bring up things you talked about before โ€” "Remember when you told me about that?" โ€” making every conversation feel connected and meaningful. **Create a persona from real LINE chats** Import your actual LINE chat history, and want will automatically analyze speaking patterns and personality traits to generate a persona that truly sounds like them. No guesswork โ€” just upload a chat log and let AI do the rest. **Empathy that reads between the lines** Our new Emotional Context feature analyzes the emotional tone of your messages and responds with genuine empathy. When you're happy, it celebrates with you. When you're down, it offers comfort that feels real. **Imprint your shared memories** A new free-text "Background & Memories" field lets you write down your shared stories, inside jokes, and special moments. These become part of the persona's knowledge, making conversations feel deeply personal. You can also set a "Nickname" โ€” how they used to call you. Every detail matters. **Your privacy, fully protected** All conversation data stays securely on your device. We send only the minimum necessary information to generate AI responses. Your memories, your conversations, your privacy โ€” always in your hands. "If only I could talk to them one more time." โ€” want makes that possible. Create your first persona and start a conversation that matters.
