Description

PRISMA makes Monte Carlo simulation accessible to anyone with a spreadsheet. Upload messy ops data, get instant dashboards and insights, then simulate decisions before you commit. Ask "What if I cut from 7 to 5 drivers?" - 1,000 simulations run, showing probability distributions and sensitivity analysis. Verdict: don't cut (34% positive). Follow up: "Keep 6, remove the weakest?" - PRISMA identifies the problem driver, simulates again: 63% positive. Not just answers - better questions. Built with Claude Code and Opus 4.6. The full reasoning chain: understanding messy data, generating structured tool_call specs, formulating simulation parameters, translating probabilistic outputs into business advice. ~12K lines vanilla JS. Client-side - no data leaves your machine. Vercel deployed. Built by an ops leader who scaled teams across Big Tech and high-growth startups.

# PRISMA

**See what happens before it happens.**

PRISMA is a decision intelligence engine that puts probabilistic decision support in everyone's hands. Upload any messy spreadsheet — ops, logistics, finance, staffing. PRISMA instantly builds dashboards, surfaces what your data is hiding, and lets you ask "what if?" questions that trigger 1,000 Monte Carlo simulations. You see the probability of every outcome before you commit. No data science degree. No configuration. No code. Just decisions backed by evidence.

> Built for the **"Built with Opus 4.6" Claude Code Hackathon**, Feb 2026.
