Hikki is a simple local wiki based on Markdown.
Notes are written and edited using an embedded Kate editor, and displayed on an embedded Webkit browser. You can switch between editing mode and display mode seamlessly using the toolbar or by using the shortcuts Alt+1 and Alt+2.
There's no save button in Hikki. Everything is saved automatically and rendered immediately.
The syntax is standard markdown, with an extension for [[interlinks]]: write something inside [[double brackets]] to create a link to another note. Clicking on the link will bring you to a newly created (empty) note, that you can then edit.
This product includes software developed by David Loren Parsons.
