Desktop Wiki and Personal Knowledge-base

Zim is an open source free lightweight note-taking application in a form of desktop wiki. It allows you to organize your notes, articles, resources, and ideas all in one place, connect them together using page links, attach media and documents and more.

Zim is a graphical text editor used to maintain a collection of wiki pages. Each page can contain links to other pages, simple formatting and images. Pages are stored in a folder structure, like in an outliner, and can have attachments. Creating a new page is as easy as linking to a nonexistent page. All data is stored in plain text files with wiki formatting. Various plugins provide additional functionality, like a task list manager, an equation editor, a tray icon, and support for version control.

By default, Zim supports wiki syntax and a long set of shortcuts keybindings that makes writing a pleasing experience.

It comes with a spell checker plugin, that you can enable or disable.
