Lex provides definitions from Den Danske Ordbog within its articles. Readers can comment, suggest edits or new articles, and contribute images, though editors must approve proposals. Lex says articles may contain errors or omissions and invites correction suggestions. Institutions, public authorities, and businesses can license content through Tekst & Node. Text and data mining, including AI training, requires individual permission. Lex serves public education, including schools, universities, educational institutions, and libraries.

Store norske leksikon is a free reference work with expert-written articles based on research. Its encyclopedia covers subjects and fields in both Bokmål and Nynorsk. Subject editors maintain their areas and provide academic quality control. Registered readers can propose new articles or changes, which an editor reviews before publication. Articles are intended to use clear language, structured headings, definitions, fact boxes and links to related material; many are adapted linguistically for school pupils. SNL says the articles are useful to pupils, students and teachers. Reading does not require an account, though submitting proposals or comments and sending internal messages does. The publisher says AI-generated text may not be published in the encyclopedia. Its works offer an open API and metadata marked for free reuse, and the encyclopedia is updated daily. SNL aims to meet most WCAG 2.0 AAA requirements and all AA requirements. Some explanatory image captions are not adapted for screen readers, although the relevant articles also provide image information in text. The encyclopedia is available on the web, through an API and on iOS.
