For example, in my book I can see what each of my characters is thinking as they have different ideas about the story. With text analysis, you can do several things to your text. You can do a quick word count, do some analysis, or do some reading of your text and see what people are talking about. Most important, you can also flatten the text of your book. Just as your text will look better if you flatten your text, the final product should be better either. For more information on the nitro text analysis tool, click here. Top Tip: Tilt and Flatten I like to use the tilt and flatten tools, along with the text analysis and reading tools, over and over again. I like to see what the reader is thinking and how my text stands out amongst my text, and then use the tilt and flatten tools to really get a sense of my text. In my book I do the following: 1. I usually use the text analysis tool to check for a word count. (You can use the text analysis tool with the other two tools, too for extra checking). 2. Then I use the tilt tool to find specific words/sentences that I want to flatten (or “tilt). 3. Then I do some reading of my text and see what they are talking about.
