Description

Current version: 4.1.0

OutWiker is a free, open-source, cross-platform note-taking application that stores notes in a tree structure. Such programs are often called outliners, personal wikis, or tree-structured editors. OutWiker's main difference from other similar software is that it stores the note tree as regular directories on the disk rather than in a single file. In addition, you can attach any number of files to each note. You can find more about other features in the Features section.

OutWiker supports different page types: HTML pages, pages using wiki notation (the most functional page type), plain text pages, and with the Markdown plugin, you can add another page type — pages in Markdown format.

Special thanks to the developers of the famfamfam.com, yusukekamiyamane.com, and fatcow.com websites for the free icons used in OutWiker.

OutWiker is distributed as open-source software under the GPL 3 license. The source code is available on GitHub.
