Wiki Here, Wiki Now

Wiki here, Wiki Now is a Ruby on Rails application that allows users to create wikis and collaborate on other wikis. Users can pay to upgrade their membership, allowing them to view and create private wikis.

The app is deployed on Heroku:

The source code is here on GitHub:


  • There are three types of users: standard, premium and admin.
  • Users can create a standard account in order to create, edit, and collaborate on public wikis using Markdown syntax. Anyone can view public wikis.
  • Users can pay to upgrade their account to Premium in order to view and create private wikis.
  • Premium users can allow others to view and collaborate on the private wikis they create.
  • Premium users can downgrade their account back to Standard.
  • When a user downgrades his or her account, his or her private wikis will automatically become public.

NOTE: Upgrading to Premium is done with Stripe. It is deliberately set to test mode. The upgrade itself occurs when payment is processed.
