Book and Manuscript Editor FAQs

1. Does ProWritingAid help with all stages of book and manuscript editing?

Book and manuscript editing involves several stages. Most writers start with developmental editing, which involves looking at structure, logical flow, and narrative. Next comes line editing, which involves looking at sentence structure, word choice, and other writing elements. Finally, you’ll need proofreading, which involves catching typos and formatting mistakes.

ProWritingAid can help you with all of these steps, with comprehensive reports that look at both big-picture and line-level improvements.

2. Can I track my editing progress as I go?

The hardest part of editing is always knowing where to begin.

It’s important to know what you are doing well and where you could improve. A good book editing software points you toward the key changes that will have the biggest impact on your writing, while also acknowledging your wins.

ProWritingAid’s goals show how you score against real-world targets for the key editing elements for your document type. Your scores change as you edit so you can monitor your progress in real time.

3. What software integrations does ProWritingAid offer?

ProWritingAid offers many different integrations so you can edit your book or manuscript where you’re most comfortable!

Our app integrates with MS Word, Google Docs, and several browser extensions (Google Chrome, Firefox, Safari, and Microsoft Edge). Our Desktop App also has compatibility with Scrivener—allowing you to upload and edit your Scrivener files directly into our app. 

4. What is the maximum word count ProWritingAid can check?

Although ProWritingAid does not have a maximum word count, it works best when looking at fewer than 10,000 words at a time. The complex nature of our many high-powered reports requires that the tool maintains contact with our servers to function. You can break up your book by chapter to get under that word count and to avoid becoming overwhelmed with suggestions.

Ensuring your chapters are less than 10,000 words will help ProWritingAid work faster and more efficiently.

5. Does ProWritingAid have a plagiarism checker?
