Spellr.us is a website tool that is getting some attention in the blogosphere, even though it's only in "beta-invite" mode. The solution spell checks websites and provides a monitoring service that regularly checks your website for spelling mistakes. Sounds pretty good, right? If you've got hundreds or thousands of web pages and are continually cranking out new content, a solution like this make some sense. So how much does it cost? Spellr.us is apparently looking at pricing models as in the registration they are asking what users would pay for a service (less than $50 or more than $50). For that price range, it better be pretty darn good considering the variety of free resources available to web professionals already. In fact, most offline and online document creation tools like Microsoft Word or Google Docs already have spell check built in.
