Zim

Zim is a text-editing tool that's also much more than just that. Basically, it tries to incorporate the functionalities of a Wiki to your computer, with all the benefits this implies.

You can thus create a comprehensive archive of all your notes following the structure of a Wiki, easily organizing them into the appropriate categories and connecting them with different links.

Besides quick and easy text editing, the program lets you insert images and open them with any other application, from which you can edit them or add a link to the site.

Zim is something more than an advanced notepad – it's a tool that allows groups that need an efficient organization to create useful notes together.
