The built-in spell-checks used in Microsoft Word and Gmail are serviceable enough, but if you're really looking to improve your writing, you'll need more than a gentle nudge when you use the wrong form of its. With the ProWritingAid bundle, you'll get thorough, informative feedback on all facets of your writing, so you can draft cleaner (and clearer) work emails, have a mistake-free LinkedIn profile, and tighten up your own fiction.

This downloadable program provides you with thousands of suggestions to improve the spelling, grammar, and readability of your writing. These aren’t just the usual corrections that a standard spell-check gives you; these tips include quizzes and video explainers to help you learn in different ways, and there are even fixes tailored to your specific writing style. And since writing can't always be categorized as right or wrong, you'll also get tips on more subjective issues like vague wording, sentence length, repetitiveness, and more.

ProWritingAid currently sports a 4.8-star rating on Google and is compatible with Microsoft Word, Google Docs, Open Office, Scrivner, and Final Draft. Right now, you can get a lifetime subscription to the bundle on sale for $200.
