WikidPad is an open source, Python-based wiki-like notebook for storing thoughts, ideas, todo lists, contacts, and other notes with wiki-like linking between pages.
The WikidPad system uses a database to tie together individual text documents that the user creates into a wiki-like notepad. Wiki-links can be created by writing a word in CamelCase or enclosing a word or words with single brackets, allowing easy ways to create a mini-wiki on a certain subject easily. Single wiki pages and complete wikis can be exported to HTML.
