AI-native CRM that builds itself and does work for you

Hi PH 👋 I built HistoryPrint as a weekend side-project that turned into something bigger. The core idea: every city has a historical fingerprint. Vienna's is shaped by empire and culture. Cape Town's by colonial collision. Cusco's by the Inca. The tool quantifies that with proximity-decayed scoring and surfaces it as a single archetype — "Plague Walker", "Born in Fire", "Heir of Enlightenment". Under the hood: 13,000 curated Wikipedia/Wikidata events, exponential proximity decay, multi-regional event resolution (Black Death surfaces in 1353 for Moscow, 1348 for Florence). Anti-tampering on the leaderboard via signed HMAC tokens. Per-city OG cards generated at runtime, cached for 24h. Try a few cities and tell me what archetype you got. I'll be replying all day.
