Neumann
Neumann turns rough guesses into a realistic range of outcomes for any plan built on uncertain numbers: project cost and budget estimates, schedules and delivery dates, capacity, revenue, and investment returns (NPV, IRR, payback). It runs a Monte Carlo simulation and reports percentiles, the chance of hitting a target or staying within budget, and which input matters most. Free tier, no sign-in: 3 free runs per day. After that, a run costs 1 credit ($0.50), or 5 for a large one.
