About Stonetotem

Stonetotem is being built as a GPS for life: a way to compare choices, understand their possible effects and work towards a goal. You choose what matters to you.

The method, in plain words

You describe a decision, your options and your goal. AI helps interpret the question. Statistical calculations use measured data to estimate outcomes; a fluent explanation is not evidence that an estimate is correct.

The development programme aims to connect comparisons, effects across different parts of life and a plan that changes as you report what happened. These are development objectives; this preview does not establish that every question or domain has been validated.

Estimates depend on the available data, assumptions and time horizon. Check the sources and limitations shown with each result. We do not publish an overall accuracy claim here.
