A humanistic decision companion

Think better.
Choose more humanly.

Desiderius asks the difficult question first, verifies the facts and lets code do the arithmetic.

AI for judgement Data for truth Code for arithmetic

What are you trying to make a better decision about?

I will keep facts, calculations and judgement clearly separated.

Code for arithmetic

Which powertrain truly fits?

Enter your own assumptions. Desiderius does not invent market prices.

Housing

Rent or buy?

Compare cash flows without pretending that a home is only a spreadsheet.

Energy

Which measure comes first?

Compare insulation, solar panels and a heat pump using the same assumptions.

Life is bigger than transport and property.

Choose a starting point; Desiderius will then ask what truly matters.

Life

Compare major choices through freedom, security, meaning and your own values.

Money

Bring income, major recurring costs and a realistic savings goal together.

Sustainability

Prioritise actions by real impact, feasibility and durability.

Travel

Compare price, time, emissions, comfort and the purpose of the journey.
