Hey Product Hunt 👋 Solo dev here. I built Altworld out of a specific frustration: long runs in chat-based AI games drift. The story forgets your debts, your enemies, your dead. By turn 40 the world is soup. Altworld flips the order of operations. Every action you type first updates a structured world database — factions, prices, rumors, relationships, locations — and only then is the story narrated from what actually changed. So turn 50 still remembers turn 3. Consequences compound. Reputations follow you. What you can do today: • Live a life in a curated historical world — or forge your own from a plain-language pitch and publish it for others • Play with friends: multiplayer sessions share one persistent timeline via invite link • Start free in the browser: 10 guest turns, no account, then free daily Candles I'll be here all day — ask me anything about how the simulation works under the hood, or why I think 'the world is the memory' beats bigger context windows. 🕯️
