Idea 6 · Analysis Members
Your numbers replayed through every start year since 1965: which ones your money would have lasted through, what made the hard ones hard, and what a change could have done, a move you saved on Relocation too. Or the same years shuffled into 1,000 made-up futures, to see how often your money lasts when a bad run can come at any time.

How you learn
Once, on Your money. Round figures are fine.
Spend a little less, invest a little more, take a year off.
Every page follows, so you see which habits matter most.
A short article, or ask AI to explain what you see.
Save your numbers each month and watch your what-ifs move.
Claude, an AI model from Anthropic, explains the page you're on from your numbers and the context you choose to give it: what drives the result, what it leaves out, and what to try next. It never tells you what to do with your money.
An example, for on FI path
Try next: lower the expected return by one point and see how far the stop age moves.
