Very beta.
Change the urlPrefix
variable in copyedit.js
to reflect your local server path.
Add a bookmarklet thus:
javascript:var%20script%20=%20document.createElement('script');script.setAttribute('src',%20'http://copyedit.dev/copyedit.js?1234');document.getElementsByTagName('body')%5B0%5D.appendChild(script);
Future releases will improve this process!
