Playground

Paste state, stack questions, watch probabilities wiggle in the browser without touching billing.

What it does

Official browser sandbox for System One. Tune Choice, Score, and Noul questions against real state, inspect vectors, and sanity-check thresholds before you embed calls in services. Cheaper than deploying a staging stack just to see if your question schema is nonsense.

Browser sandbox for stacking questions against sample state. Tune thresholds with your eyes before you tune them with incident reports.
