About

Zim is an open-source desktop wiki used to maintain collections of linked notes, journals, task lists, and attachments in plain text files.

Zim is one of the clearest remaining note-native desktop wiki gaps. The official site describes it as a graphical text editor for collections of wiki pages stored in folders as plain text, with links, images, attachments, and plugins for task lists and version control. It is very much a note and personal knowledge product, not a project platform in disguise.
