Note: The Marketers Toolbox series teaches our readers about new technology we're using (or experimenting with) that proves to be useful, productive, or just plain entertaining. As a marketer's secret weapon, Setup believes that the tools we use are vital to our success, thus, a marketer's toolbox is truly one of our most important resources.

Not every Chrome extension (or native app) can claim to make you a better writer, and when 50% (or more) of your marketing strategy involves content creation, a tool like Grammarly can go a long way.

The basic (free) version of this tool analyzes your text to find and correct up to 10 times more spelling and grammatical errors than a word processor.

If you're willing to pay a premium for Grammarly's professional proofreading, the app can also offer suggestions for word synonyms, sentence composition, and overall vocabulary enhancement to synthesize and strengthen your writing.

A month-to-month subscription to Grammarly costs $29.95/month. Quarterly and annual subscriptions are billed as singular payments of $59.95 and $139.95, respectively, or $19.98/month and $11.66/month.

Grammarly's coup de grâce is its plagiarism functionality, which scours a database of more than 8 billion web pages to check for any kind of likeness to your work.
