OpenSpritz is an extremely crude implementation of Spritz in JavaScript. It works as a bookmarklet to add Spritz-type speed reading to every page.

OpenSpritz needs you! If you find bugs, have feature requests, or have other needs, please help out!

The best way to contribute is to start a new ticket, or to work on an existing ticket. If you find a website which doesn't work with OpenSpritz, add it to this ticket so that it can be diagnosed and fixed.

OpenSpritz currently needs a little more love to make it work with JSONP and needs a better method of detecting the presence of jQuery, so those are some good places to start.

A Note About the Name

OpenSpritz has nothing to do with Spritz Incorporated. This is an open source, community created project, made with love because Spritz is such an awesome technique for reading with. (Please don't send us a DMCA take down request! That'll only backfire on you anyway. We love you.)
