WorldSim
Multi-agent simulation for policy & crisis prediction
WorldSim automatically generates parallel societies from real‑world data Each AI agent has independent personality, memory, and social relationships. It supports multi‑domain coupling — social media, economy, policy, and epidemics — to capture complex real‑world interactions. The platform delivers emergence‑based predictions, counterfactual analysis, and causal inference for policy makers, researchers, and crisis managers.

As a researcher in computational social science, I saw the same problem again and again: governments and organizations wanted to test policies or predict crisis outcomes, but existing simulation tools were either too simplistic (simple equation‑based models) or required months of manual agent programming. I founded WorldSim to change that. The first prototype only simulated opinion dynamics on social media with a few hundred agents. Then we added economic behavior, then policy response, then disease spread — and realized the real power comes from multi‑domain coupling. The hardest part was giving each agent persistent memory and personality without blowing up compute costs. Today, WorldSim can generate a parallel society of 1M+ agents from any real‑world event or policy document, run multi‑domain simulations, and output a prediction report with counterfactual scenarios. We’re launching in private beta for researchers and policy advisors. Join the waitlist to be among the first to simulate the future.

Who hunted WorldSim?
WorldSim was hunted by tian hao. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
