Editing your own work can be difficult. If you don't give yourself enough time between writing and revising, everything might sound good. ProWritingAid is a webapp that edits your work for writing style and gives you immediate feedback.
ProWritingAid points out cliches, unnecessary "glue words" (such as who, what, when, where, and why), and redundancies (such as "still remains"). It's a great free tool, especially if you can't have another person carefully look over your work, but you'll have to pay to unlock features like the plagiarism checker. ProWritingAid does have a Chrome plugin available, but based on the abysmal reviews from the web store I suggest sticking with the web editor.
