Hello Product Hunt community! 👋 I’m the founder of HeritageValue (Heva), and I’m thrilled to share our launch with you today. As a lifelong collector, I’ve always seen a massive gap between the physical beauty of rare books—some dating back centuries—and the fragmented way they are appraised and preserved in the digital age. We built Heva to solve this. By combining specialized AI training with a database of nearly 100,000 metadata entries, we are moving beyond "guesswork" to provide professional-grade appraisals for rare Vietnamese literature, antique manuscripts, and global artifacts. What we’re bringing to the table: AI Deep Scanning: Precision analysis of historical nuances. Digital Heritage Passports: Secure, blockchain-backed certification. A Bridge to the Future: Helping local "antique hunters" connect with a global marketplace. Our goal is to ensure that every historical item has a verified, secure, and digital legacy. I’d love to hear your thoughts on our AI-driven valuation model or our use of Digital Heritage Passports. I’ll be here all day to answer your questions. Looking forward to your feedback!

Most AI models give you a subjective paragraph. Heva provides a Scientific Appraisal Framework. Whether you appraise 1 item or 10,000, Heva applies the same rigorous standards—analyzing Scarcity, Physical Condition, and Historical Provenance in a synchronized way.

We’ve turned the 'art' of collecting into a 'science' of data. This structured approach is what allows us to issue a Heritage Passport that collectors and auction houses can actually trust
