Ask YC: What tool do you use to crawl and spell check your entire website?
What tool do you use to crawl and spell check your entire website?
But, I probably wouldn't do this, because spell checking is irrelevant. It won't tell you if your prose makes sense, it won't tell you if you've used the wrong words, and it won't tell you if the content is out of date. It's best to go through your site and see if it all makes sense. Only a human can do that.
What I'd like is an integrated grammar checker.
