Decision tools
The NESTOR methodology, hands-on – right in your browser.
Seven interactive tools guide you through the essential steps of robust decision preparation: from diagnosis and alternative comparison to a finished Decision Passport – and, for energy projects, to a marketable project file.

How the tools work
01
Rule-based assistance
The tools apply the review rules of the NESTOR framework: they detect gaps, prioritize assumptions, and assess decision readiness – transparently and traceably instead of as a black box.
02
Your data stays local
All input is stored exclusively in your browser (localStorage). No data is transmitted to any server.
03
Results you can take with you
Every tool produces a structured result that you can copy as Markdown, download, or print – a starting point for working with your team.
The tools do not replace professional advice or a case-by-case review. The assessment logic is rule-based and deliberately transparent.
