Grammarly catches my mistakes and corrects them on the fly, thus saving me lots of time and effort in proofreading. I can now create flawlessly written submissions every time, without having any worries about those renegade typos that used to escape even multiple proofreadings. I cannot imagine writing without Grammarly working in the background and making me look like a seasoned pro. Highly recommended! Don't type a page without it. Bob's yer Uncle.
