Nothing
Called Spellist, this online spell checker for websites uses the Google API
to search for spelling mistakes. You just type the URL and it will
quickly point out the potential spelling mistakes that may be in the
text or even the meta description of the page.
Spell check your website like a Word document
There are no advanced features like scheduled spell checks, RSS,
alerts or support for adding new words to the dictionary but as a quick
and simple tool, Spellist does the job
