Free encyclopedia

To create a free encyclopedia, you can use open-source wiki software like MediaWiki (powering Wikipedia) or simpler tools like DokuWiki/BookStack for a self-hosted project, or platforms like Notion/Obsidian/LogSeq for personal knowledge bases, focusing on gathering reliable sources, structuring content (articles, categories, history), and deciding on collaboration levels, with options ranging from full public editing (like Wikipedia) to private use.
