Klexikon

What Klexikon is

Klexikon is a free German-language online encyclopedia written for children roughly 6 to 14 years old. Its articles use clear wording and short sentences intended for young readers, and the project says it has more than 3,500 articles. MiniKlexikon adds more than 1,500 articles in especially simple language for beginning readers, German learners, and children with additional learning needs. Articles use child-appropriate images from Wikimedia Commons, with at least one image called for in each article; some also include Tagesschau explanatory videos. Klexikon is available on the web without a login. The project describes it as ad-free and says it does not collect personal data. Article text is published under the Creative Commons Attribution-ShareAlike license, which requires attribution and the same license for reuse. Children can send article requests, questions, or error reports. Adults interested in contributing apply by email and normally receive an account after an introductory course; new contributors must be at least 18. The project also offers school workshops with research tips and collaborative article improvement.
