Zim aims to bring the concept of a wiki to your desktop. Every page is saved as a text file with wiki markup. Pages can contain links to other pages, and are saved automatically. Creating a new page is as easy as linking to a non-existing page. This tool is intended to keep track of TODO lists or to serve as a personal scratch book. But it will also serve you when writing longer and more complicated documents.
A “desktop wiki” means that we try to capture the idea of a wiki, not as a webpage but as a collection of files on your local file system that can be edited with a GUI application. The main focus is a kind of personal wiki that serves for all kind of notes: todo-lists, addresses, brainstorm ideas etc.
But we want to go further than just a wiki filled with random content. It should also be possible to use you random notes as the basis for more structured data: articles, presentations etc. Zim will not include tools to layout a presentation or something like that, you should use your office suite of choice for that, but it should be a tool that can deliver all the content for a presentation in a form that only needs a template and some layout before usage. Therefore certain features normally not found in wikis will be added.
