Cowyo
A self-contained wiki server that makes jotting notes easy and fast
cowyo is a self-contained wiki server that makes jotting notes easy and fast. The most important feature here is simplicity. Other features include versioning, page locking, self-destructing messages, encryption, and listifying.
Editing
When you open a document you'll be directed to an alliterative animal (which is supposed to be easy to remember). You can write in Markdown. Saving is performed as soon as you stop writing. You can easily link pages using [[PageName]] as you edit.
History
You can easily see previous versions of your documents.
