L위키 (엘위키) is a collaborative, web-based wiki platform aimed at fostering a comprehensive and liberal information resource for Korean-speaking users. The brand's name, which embodies dual meanings such as "library" and "liberal," signifies its goal of providing a clean and accessible space free from biases and inaccuracies.

Currently hosting 536 documents, L위키 encourages contributions from the community, allowing anyone to edit and enhance existing articles. This initiative seeks to address the lack of liberal perspectives within Korean media, promoting democratic values and transparency in information sharing. Users can communicate through community forums and participate in discussions about site policies and guidelines.

L위키 also maintains a presence on social media platforms like Twitter and Mastodon, keeping users informed about the latest updates. Users are welcomed to join and collaborate in creating a diverse and rich knowledge base. Despite its open and collaborative nature, L위키 advises that the content may reflect individual authors' views and is not guaranteed to be unbiased or error-free.
