After the Deadline now checks your grammar, spelling on Google Chrome!
Now, Google Chrome users can get in on the grammar-y goodness: After the Deadline is now available from the Chrome Extension Gallery.
The new extension is loaded with options, allowing you to whitelist certain phrases and websites, automatically check textareas prior to submission, and optionally look for bias language, clichés, double negatives, and more.
In addition to English, ATD also supports French, German, Portuguese and Spanish. As with most grammar checking tools, After the Deadline isn't perfect. It didn't catch some intentional errors I threw at it like a random capitalized word in the middle of a sentence or misplaced or things that had been shuffled around. For example, "Where I am going at?" avoided detection.
When ATD does spot something wrong, it gets underlined. Click one, and you can see what kind of error was detected, possible replacements, and a link to an explanation. You can also ignore a particular error -- or choose ignore to never be bugged about it again.
Still, having After the Deadline installed is better than no grammar check at all -- especially if you need the things you type in Chrome to look erudite and professional.
