ReaNOS takes a decision you're turning over — a move, a job, a problem, a what-if — and maps it into the paths genuinely open to you. Each one weighed honestly, with what it rests on in plain sight and open to challenge. It won't tell you the answer. It helps you reason your way to one.
A clear path from a situation you can't hold in your head to one you can stand behind.
Describe the situation in your own words. Add facts and assumptions as first-class evidence — lock the facts that are fixed.
Claude maps it into distinct paths, each with a plausibility, a confidence, the evidence behind it, and what it rests on.
Play any path forward several moves, then compare a branch you took against one you didn't — side by side.
Have it try to break its own reasoning, then add new evidence and watch the weighting visibly recalculate — and why.
The intelligence underneath is structured, inspectable, and accountable.
Three separate, honest axes — so a bold option can read as "credible but I'm not sure," never a false certainty.
Add context and the paths re-weigh in front of you, with a plain-language note on what changed and why.
Challenge any path: the weakest assumption, a sceptic's objection, a pre-mortem, and whether the odds are inflated.
A living map of your committed path and every what-if branch you explored — click anywhere to revisit it.
Life, Career, Problem-solving, Foresight, History, IT, Mechanic and Medical (information only) — each a tuned lens on the same method.
