Choosing topics
We choose topics based on their interest for an international audience, their practical usefulness to the reader and the quality of the available evidence. We never invent audience statistics or search volumes.
Sources and verification
We rely first on official sources: publishers' pages, public bodies and international institutions. Time-sensitive information (prices, offers, features) carries a verification date. Prices may vary by country, currency and tax: always check the amount shown at checkout.
The role of artificial intelligence
AI helps us research, structure and write. It does not replace review: every article is checked before publication, and sensitive topics are always validated by a human. The AI is forbidden from inventing figures, quotes or sources.
Facts and analysis
We separate what is established (sourced facts) from our own reading and ideas. The latter are introduced with labels such as “NEXUS analysis” or “Idea to explore” and should not be read as established facts.
Our comparisons
A comparison states whether it relies on a direct test or on the publishers' documentation. Unless stated otherwise, we have not tested the compared products ourselves. Rankings never depend on an affiliate commission.
