CORE ANALYSIS · FREE
A complete diagnostic, in minutes.
Upload a Word document, PDF or text file and get a detailed reading across structure, craft and mechanics. Every score shows the counts it was built from, and anything the engine cannot measure is described rather than scored.
Structure
Understand the shape of your story.
How much of each chapter is scene against summary, where that thins or spikes, chapter length against the book’s own norm, and whether the cast persists.
Narrative structure, described with the chapters to inspect
Pacing heatmap by kind of prose

Reader-momentum signals
Craft
Find the writing that’s getting in the way.
Judged for the passage it sits in. A long sentence in a reflective stretch is measured against your other reflective stretches, not a fixed number.
The air tasted like ash, and Narubi watched the skyline burn. She had survived worse, but this felt different.
It wasn’t just a city falling.
It was a choice.
Book Intelligence · advisory
The emotion is summarised where the scene could carry it
“This felt different” names the feeling instead of letting the reader find it. The image before it, ash and a burning skyline, is doing the work; consider what Narubi does with her hands, her breath, her attention.
Interpretation, not measurement. Your scores are unchanged.
BUILT FOR YOUR STORY
20 genres. Analysis that understands the difference.
Genre changes what good writing looks like. A self-help book is not judged against fiction goals, a thriller is not asked to slow down, and the left rail tells you what a reader of your genre comes for.
