Support our work

Core knowledge remains publicly available without charge. Voluntary support helps us research, verify, develop, and maintain it over the long term.

What support enables

• research, source access, editorial work, and factual review;
• photographs, illustrations, diagrams, and other educational visuals;
• licences, permissions, attribution, and rights review;
• technical development, hosting, security, and platform maintenance;
• future publicly available publications and educational work.

What support does not buy

• editorial influence, a changed conclusion, or a lower evidence standard;
• a recommendation, ranking, preferential visibility, or concealed advertising;
• partner, sponsor, or supporter status that is not genuinely agreed and documented.

The current funding model and any future relationship material to assessing independence are published on Funding and independence.
