Not a grammar checker. Not a spell-checker. A structural engine that reads your manuscript the way an editor does — and tells you exactly what isn't working, before you pay someone else to find it.
Diagnose Your Manuscript FreeScores your manuscript on six reader-dropout dimensions: hook strength, clarity, forward motion, specificity, redundancy, and payoff. Tells you which section loses readers first and exactly why.
Detects your story arc across four quarters of the manuscript. Rising action, climax, resolution, and cliffhanger patterns scored and mapped. Flags a sagging middle before you submit.
Visualizes the balance of action, dialogue, description, exposition, and reflection across your manuscript. Spots where your pacing stalls or rushes.
Scores tag discipline, conciseness, naturalness, and show-not-tell within dialogue. Flags exposition dumps, repetitive speech patterns, and over-attribution.
Maps 32 emotions to their physical manifestations. Flags "she felt angry" and suggests "jaw tightened, hands clenched, voice sharpened." Not a generic rule — a specific replacement.
Six sub-scores: tone consistency, flow, word precision, sentence pacing, POV discipline, and extraneous language. Each scored independently, each improvable.
Passive voice with active-voice rewrites. Adverbs mapped to stronger verbs. 90+ clichés flagged. Weak verbs replaced. Wordy phrases trimmed. All with specific suggestions, not just flags.
2,000+ grammar rules via LanguageTool: comma splices, run-ons, subject-verb agreement, confused words, tense shifts, dialogue punctuation. Proper nouns and invented names filtered to avoid false flags.
Your first pages scored on hook strength, tension, specificity, clarity, forward motion, and genre-matching. Tells you what a cold reader — or agent — encounters in the first 500 words.
A full developmental editorial pass: character arc, stakes, conflict engine, voice consistency, pacing at the chapter level. The kind of feedback a developmental editor gives at $2,000+. Delivered in one click.
Identifies your three weakest passages by paragraph, explains exactly why each one loses reader momentum, and suggests a concrete rewrite. Specific text from your manuscript, not generic advice.
A query letter scaffold drawn from your manuscript’s actual story beats, genre, word count, and themes. Not a template with blanks to fill — a draft built from what’s in your book.
Identifies comparable published titles based on genre, themes, voice, and structural patterns in your manuscript. Gives you the comp titles agents ask for, grounded in what you actually wrote.
Five distinct reader personas respond to your manuscript: the casual reader, the genre purist, the literary reader, the agent, and the skeptic. Surface problems that only real readers would catch.
An honest assessment of where your manuscript stands against current publishing standards for your genre. Not a vanity score — a gap analysis between where you are and where you need to be.

Nonfiction scoring weights authority establishment, structural clarity, reader promise, and argument momentum differently from fiction’s tension and character arcs.
This tool does not replace a copy editor, line editor, or proofreader. It does not guarantee publication. It does not rewrite your book. A developmental editor, a copy editor, and a proofreader are still part of the path to a finished, publishable manuscript.
What AuthorScrolls does: finds the structural, stylistic, and craft problems you can fix yourself — before you spend money on professional editors to find them for you. Most writers go through two or three rounds of expensive editing before the core problems are addressed. This is the step that changes that.
No credit card. No limit on how many times you analyze. The full diagnostic engine is free.
