Top of the line program. You have a 5 star winner here. I have been using your program, and I have become a better writer from it.

I have tried every editing tool I can think of out in the interweb. But, this knocks spots of everything and is free.

Easily see the problems with your writing

Each report concentrates on a particular aspect of your writing to help you focus on it. Reports clearly show where there is room for improvement. As you edit your writing you'll also learn and your writing will improve.

The overused words report to the right is one of our most popular. It compares your text to published works for the frequency of certain commonly overused words, and highlights where you have overused them. Reducing the occurrences of these words will make your writing clearer and more compelling.

This is the best.. this looks like the ultimate as a writing aid.

Authors & Writers

For many professional writers ProWritingAid is the perfect way to save money on professional copyediting services. ProWritingAid will catch many of the same things as a professional copyeditor but without the cost.

A good professional copyeditor will cost at least $40 an hour. Using ProWritingAid before sending your work to a copyeditor will save you money and leave the editor free to concentrate on more important stylistic issues.

ProWritingAid has a number of reports specifically designed for the professional novelists, such as the pacing report that will highlight areas of slow pacing (e.g. back-story), allowing you to easily spot areas with too much back-story and not enough action.

Students & Academia

ProWritingAid is used by many students to improve their writing and check for plagiarism. Whether you want to improve your thesis, or polish your paper, ProWritingAid will highlight the areas of most weakness so that you can make the most out of the time available to your for editing.

If you were to use a professional thesis or dissertation editing service then the first thing they will do is use a tool like ProWritingAid to check your text for all manner of errors. Once they have this list in hand then they will feel that they have fulfilled part of their contract with you and therefore don't need to look at your thesis in the more critical ways of structure and content. By using ProWritingAid you remove these errors allowing them to concentrate on more important issues.

Business & Government

In this competitive economy it has never been more important to effectively communicate with your clients and colleagues. ProWritingAid will help you to improve your writing so that it is clearer and more compelling.

The 2010 Plain Writing Act (in the US) highlighted the need for government departments to communicate effectively and clearly. Improving the language of legislation will help increase participation and understanding. Many government departments now use tools like ProWritingAid to enhance their writing.
