Optional AI context

On a country profile, you can choose to request a short AI-generated geography or historical-culture story. The app asks for consent before each request. This feature sends the country name and an app-written prompt through the WorldFacts API gateway to an AI service and requires Internet access. The app does not save AI-story history. AI output may be incomplete or mistaken.

The country catalog, search, profiles, comparison, quizzes, sources, and licenses work without an AI request. Population values are source snapshots with their reference year. UTC offsets are reference information, not a live daylight-saving-time service.

WorldFacts is free educational software with no ads, accounts, subscriptions, in-app purchases, Firebase, or analytics. Quiz results and appearance preferences stay on the device, subject to Android backup or device transfer.

WorldFacts is independent software. It is not a government app, statistical authority, travel advisory, mapping service, or official historical source.
