Hi Product Hunt community! 👋 I’m Cristian, the solo creator behind Opendria. I’ve always believed that learning history and philosophy should feel like an active journey, not a dry lecture. That’s why I spent the last year building Opendria—an interactive library where you can converse directly with 80 of history's greatest minds, including Albert Einstein, Leonardo da Vinci, Aristotle, and Isaac Newton. What makes Opendria different? Conversational Continuity: The mentors aren't transient chatbots. They have a custom memory layer that remembers your past interactions. Emotional & Somatic Vectors: Their mood, vocabulary, and response style change dynamically based on the relationship state you build with them. Intellectual Accuracy: They speak strictly within their era's knowledge boundaries and dialect. I've designed a generous free tier so everyone can start chatting right away. I’d love to hear your thoughts, feedback, and advice on the interface, the dialogue flow, or characters you’d like to see added. Thank you so much for your support! 🚀
