Some entries are generated by Grok, a large language model owned by the same company, while others were forked from Wikipedia, with some altered and some used nearly verbatim.

Deletionpedia was an online archive wiki containing articles deleted from the English Wikipedia. Its version of each article included a header with more information about the deletion such as whether a speedy deletion occurred, where the deletion discussion about the article could be found and which editor deleted the article. The original Deletionpedia operated from February to September 2008. The site was restarted under new management in December 2013.

Hamichlol ( "The Entirety") is a censored wiki-based Internet encyclopedia project for the Haredi public. Most of the articles on the site are exact copies (as of the date they were copied) of articles from the Hebrew Wikipedia or re-edited versions of Hebrew Wikipedia articles, adapted for the Haredi reader, while original articles currently constitute only a small portion of all the articles on the site. The site is managed and operated by the Institute for Literacy and Proper Knowledge, which was established for the purpose of creating the site.

Veropedia was a free, advertising-supported online encyclopedia launched in 2007. Veropedia editors chose Wikipedia articles that met the site's reliability standards; information was then scraped, or chosen by an automatic process, and thereafter a stable version of the article was posted on Veropedia. Any improvements required for articles to reach a standard suitable for Veropedia had to be done on Wikipedia itself. This model was intended to improve the quality of both projects.

WikiPilipinas (formerly known as Wikipiniana) was an online, free content website which billed itself as a combination "non-academic encyclopedia", web portal, directory and almanac for Philippine-based knowledge. Like Wikipedia, it contains various articles on Philippine-related topics. Unlike Wikipedia, many of the articles cover topics that would otherwise be deemed unencyclopedic by the stricter Wikipedia. The service for example, promotes the concept of original research and eschews the larger encyclopedia's neutral point-of-view principle.
