Case Studies

Real problems. Real methodology. Real outcomes.

These are not thought experiments. Each case study documents an actual task, carried out using the tools and methodology described on this site, with a real person trying to get something done.

The range is deliberate. Genealogy research that had stalled for years. An inheritance tax question that confused even with professional guidance. A car purchase decision with specific constraints. A garden that needed watering while its owner was away. An engineering question with only one precedent in the world. A travel insurance policy expiring in three days.

Segue o teu destino, rega as tuas plantas, ama as tuas rosas.
Follow your destiny, water your plants, love your roses.
Fernando Pessoa, as Ricardo Reis

What connects the case studies is not the subject matter. It is the approach: bringing a well-formed question, with the right context, to the right tools, and getting something genuinely useful back. In most cases, the work that would previously have taken days, or required a specialist consultation just to know what to ask, was done in under two hours.

Each case study includes what was asked, what happened, and what came back. Where the methodology is visible, we have made it visible. Where professional advice is needed beyond what AI can provide, we say so.

The serious gear is here.
