I tried the usual suspects first. Scrivener kept my book organized but never told me what was wrong with it, the line editors caught my commas while chapter nine sat quietly broken, and the chat tools wanted to write the scene for me. I needed something that reads the whole manuscript and hands me one list of what to fix and where, because my writing window is a nap, not an afternoon. This was the only one that did that, and the fact that it refuses to write my prose is the part I trust.
