Fork a choice into living worlds and watch them diverge.

AltiVerse lets you take a single decision and play it out as several alternate realities at once. Each one becomes a small living world full of people who react to the choice over time. You watch how the worlds slowly grow apart, follow any person to see how they're affected, and get a clear report at the end. It runs on your own machine, works offline, and starts with one line.

I built AltiVerse because I kept getting stuck on the same kind of question: "If we do X instead of Y, what actually happens?" — and a spreadsheet never captured the human, second-order stuff. The burnout, the broken trust, the friendships that form or fall apart. So AltiVerse lets you take one decision and play it forward as several alternate realities side by side. Each becomes a small living world of people who react over time — and you watch when and why the worlds drift apart, follow any single person to see how they're affected differently, and get a clear report at the end. A few things I cared about: Local-first — it runs on your machine and works fully offline. Nothing is uploaded. Bring your own model — plug in a local model (Ollama, LM Studio) or any OpenAI-compatible API. Your key never leaves your browser. One line to try it — npx github:LeoTheAIDev/Altiverse downloads it, boots it, and opens your browser. It's open source (MIT) — fork it, break it, build on it. I'd genuinely love your feedback: What decision would you fork first? And what would make the simulated worlds feel more believable to you? I'm reading every comment today. 🙏

What decision would you fork first?

One thing I've noticed using AltiVerse: the hardest part isn't reading the results it's deciding which question is worth forking.

So I'm curious what you'd point it at. A few that came up while building it:

A workplace policy (remote vs hybrid vs in-office)
A school or parenting rule
A team or product decision where the "soft" effects matter more than the numbers

If you've tried it, I'd love to hear: did the worlds diverge the way you expected, or did something surprise you? And if you haven't yet what's the one "what if" that's been sitting in the back of your head?
