The WikiSense project has been discontinued. It was based on a very old version of MediaWiki, and very much entangled with the Toolserver environment. A migration of the old code seems unpractical, and a complete rewrite of all tools would take a lot of effort. Please check on the ToolLabs overview page if an alternative tool exists for your need.

If you would like a WikiSense tool to be re-created, try the Community Wishlist process (or the Technische Wunschliste on the German Wikipedia).
