Comparison limits depend on the number of countries selected: up to 12 with all data, 13–50 with five data points at once, or 51 or more with one data point across at most 25 years. For schools, Universalis Junior serves primary pupils, while Universalis Éducation has secondary and higher-education editions. Education resources include mind maps, country data, a personal space, Open-Dyslexic font and dark mode. Articles are written by authors and professors and reviewed by the editorial team. The service is available on web, Android and iOS. Plans include Découverte at €1 a month, then 10,90 € per month after the first month, and Zen at €79, paid once for two years.

Wikipedia is a free encyclopedia available on the web and through mobile apps, with editions in hundreds of languages, including editions with over one million articles. Volunteer editors create and revise content, check facts, cite sources, discuss entries, and moderate the encyclopedia. The Wikimedia Foundation hosts and protects Wikipedia, while editorial decisions are made by volunteers. The Foundation says the service is available without advertising or paywalls and is funded mainly by donations, not advertising, subscriptions, or sales of users’ personal data. The official Android app supports searching articles, changing languages, saving reading lists for offline use, and adjusting themes and text size. Its listing says the app has no ads, does not track or collect data, and encrypts data in transit. MediaWiki provides a REST API for interacting with installations including Wikipedia. The Foundation publishes a privacy policy, says it prioritizes speed, reliability, and availability during traffic spikes, and publishes transparency reports twice a year. Its financial statements are independently audited annually. Wikipedia is free at free.
