These tools assist Web users rather than authors to either modify a page or supplement an assistive technology or browser. Some of these tools integrate into the browser although most of them work by proxy: using a piece of software that sits between the user and the target server to transform a page to make it more accessible. All of these tools are also evaluation tools, since pages that can not transform in a decent way are probably broken beyond repair.

• "deGrade" browser simulator.
  http://www.cgu.edu/degrade/
  By Kynn Bartlett. When designing web pages, it's important to make sure that the pages will "degrade gracefully". This means that the pages must remain usable and useful when viewed on browsers that can't handle the latest in HTML and web design -- even if they don't look as pretty.

  This web page will let you test out your page with a variety of different "degrading levels", ranging from a string of pure text to the latest HTML 4.0 tags.
