Klexikon is a free German-language online encyclopedia written for children roughly 6 to 14 years old. Its editorial approach favors clear wording, short sentences and content suited to young readers. The project says Klexikon contains more than 3,500 articles, with a further 1,500-plus in MiniKlexikon, where the language is especially simple for beginning readers, German learners and children with additional learning needs. Articles use child-appropriate images from Wikimedia Commons, and the editorial guidance calls for at least one image per article. Some articles also include Tagesschau explanatory videos. The web site is available without a login; the project describes it as ad-free and says it does not collect personal data. Article text uses the Creative Commons Attribution-ShareAlike license, which requires attribution and the same license for reuse. Children may submit article requests, questions or error reports. Adults can apply to contribute by email and normally receive an account after an introductory course; new contributors must be at least 18. Klexikon also offers workshops for school classes with research tips and collaborative article improvement.
