Editorial policy

How we prepare materials

We begin with an identifiable source. For the flag and anthem, for example, we consult the Presidency of the Republic. We write our own questions and explanations, distinguishing documented facts from study guidance.

We use artificial intelligence tools to prepare and review this first collection. Review includes comparison with the source and checking the meaning of translations; it is not a review by a human specialist. European Portuguese is the original. Each language has its own review record.

Corrections and limits

Pages show sources and review dates. Corrections go through the editorial process again. Sensitive legal content requires human review before publication. To report an error, email [email protected] with the page address and, if possible, a source.
