Manuscript Health

Manuscript Health gives you a birds-eye view of your writing patterns. No AI, no cloud — just pure algorithmic analysis of your prose. Use it to spot habits, not to follow rules.

Manuscript Health overview

  • Click Manuscript Health on the Project Overview card grid
  • Or open it from the sidebar tools menu (gear icon) under Views

Six stat cards at a glance:

  • Total words and sentences across your manuscript
  • Avg sentence length — color-coded green (12-20 words), amber (8-28), or red (outside). Good prose varies sentence length; a flat average suggests monotonous rhythm.
  • Adverb density — percentage of -ly words. Green under 2.5%, amber under 4%, red above. Adverbs aren’t bad, but overuse often signals weak verbs.
  • Passive voice — percentage of passive constructions. Green under 8%, amber under 15%, red above. Passive voice makes prose feel distant when overused.
  • Dialogue ratio — percentage of words inside quotation marks. Varies by genre (thrillers run 40%+, literary fiction around 20-30%).

Below the stats, you’ll see Repeated Sentence Starters — sentences beginning with the same two words (“She looked…”, “He was…”) shown as a bar chart. Three or more repetitions get flagged.

Your most-used -ly adverbs ranked by frequency. Look for ones where a stronger verb would serve better — “he said quietly” could become “he whispered.”

The 30 most common words in your manuscript (excluding stop words like “the”, “and”, “was”). High-frequency words may indicate repetitive phrasing.

Sentences tab with editorial guidance

Detailed editorial guidance with explain boxes for each metric:

Average sentence length, long sentences (35+ words), and short sentences (under 6 words). Varied length creates rhythm — short sentences build tension, long ones let the reader breathe.

Count and ratio of passive constructions (“the door was opened” vs “she opened the door”). Includes guidance on when passive voice is actually fine — mystery, suspense, formal prose, and historical fiction.

What percentage of your words are inside quotation marks, with genre benchmarks.

Density percentage with practical advice. Includes the threshold ranges and tips for which adverbs to cut first (dialogue tags are the easiest wins).

A table comparing every chapter side by side:

A color legend at the top explains what green, amber, and red mean. An explain box at the bottom describes each column’s thresholds in plain English.

The health indicators use fixed colors that stay distinct across all app themes:

  • Green — within the typical range for published fiction
  • Amber — slightly outside, worth a glance
  • Red — notably outside, worth reviewing (but not necessarily wrong)

These are lenses for spotting patterns, not scores. Every writer’s style is different.
