Basically it is a desktop application (runs on Windows, Mac and Linux). It is designed to help you with personal development.
Right now PDKit consists of a few module - Daylog - which is a notepad that will keep your thoughts secret; Goals - that will help you create and manage your goals; PDKit online - it's an online service for your public entries or goals.
This is a prerelease mode so I am tweaking diffrent parts of PDKit.
Currently it is free to use. In the future, PDKit may become a paid service, however I am trying hard to find a way to keep it free. I'm even considering a possibility for you to earn some money.
Just look at the publishing guide.
