Zim (software)

Zim is a graphical text editor designed to maintain a collection of locally stored wiki-pages, a personal wiki. It works as a personal knowledge base and note-taking software application that operates on text files using markdown. Each wiki-page can contain things like text with simple formatting, links to other pages, attachments, and images. Additional plugins, such as an equation editor and spell-checker, are also available. The wiki-pages are stored in a folder structure in plain text files with wiki formatting. Zim is written in Python using GTK libraries. It is open source and free software under the GPL-2.0-or-later license. Zim features several ways of organizing pages and content, and can be extended with a variety of included plugins. Pages can be browsed through an index or be sorted by tags, and pages can be navigated through a table of contents. Pages can dynamically be linked together within notebooks; links to pages can automatically be renamed when a page is renamed.
