AltiVerse — Fork a decision. Watch the worlds it creates. 🌱
Every big decision has a hidden second half you never get to see. AltiVerse lets you fork one choice into 2–4 alternate realities and run each forward as a small living world — up to ~1,000 people who move, stress out, bond, clash, spread rumours, and tell you how it felt.
It's a thinking tool for the second-order effects of a decision — a school phone ban, a 4-day week, 8- vs 12-hour hospital shifts — and a hands-on way to learn systems thinking, the scientific method, and agent-based modeling. Best of all: it's local-first, runs fully offline, and needs no account.

— What you can do —
🔱 Fork one decision into 2–4 alternate realities on a shared timeline
🧑🤝🧑 Watch living worlds of people — friendships, rivalries, rumours, burnout
👤 Click any person to compare how they specifically fare in every timeline
📊 See exactly when & why the worlds diverge (live metrics + divergence chart)
📝 Export a full report with an executive summary and a recommendation
🔒 100% local — runs offline, bring any AI model (Ollama, LM Studio, OpenAI, Groq…) or none
— How it works —
A deterministic engine drives every number (same seed → identical world, every run), so it's a real controlled experiment. An optional AI layer only writes the prose: in-character thoughts, interviews, headlines, and the final report. Turn the model off and everything still works.
— Built with —
Vite · React · TypeScript · a deterministic Mulberry32 simulation engine · any OpenAI-compatible model. No backend. No telemetry. Open source (MIT).
