4. PaperRater
This free tool allows you to upload any word document to check its grammar, spelling, punctuation, and more. After uploading your file and double-checking that all’s well, PaperRater gives you a score on a scale of zero to 100 percent, with scores below 20 percent considered poor.
Though PaperRater is useful if you want to give your word document one last look before submitting it or sending it out into the world, it isn’t very flexible.
