Decision domains

What Desiderius helps you decide

Eight areas, one method: assumptions made explicit, facts traced to official sources, arithmetic done in tested code, and the judgement handed back to you. Choose the area your question belongs to.

• Wellbeing decisionsBuild a sustainable balance of mindfulness, movement, sport, sleep and recovery—without turning health into optimisation theatre.
• Environment and sustainability decisionsPrioritise changes by real environmental impact, feasibility, cost and the ability to sustain them.
• Mobility decisionsCompare keeping your current vehicle with fuel, plug-in hybrid, battery-electric and hydrogen options.
• Housing decisionsCompare renting, buying and improving a home using local costs, rules and long-term trade-offs.
• Home energy decisionsCompare insulation, solar, heat pumps and other measures with sourced prices and local support rules.
• Money decisionsUnderstand recurring costs, savings capacity and financial trade-offs without reducing life to a spreadsheet.
• Life decisionsCompare major life choices through values, constraints, evidence and factors you can influence.
• Travel decisionsCompare cost, time, emissions, comfort and the purpose of a journey.
