AI-powered deep analysis that catches plot holes, timeline errors, character inconsistencies, and lore contradictions across your entire manuscript — so nothing slips through to publication.

Try ProseEngine FreeA scene and canon audit is a systematic, AI-driven review of every scene in your manuscript. It checks each scene against the established facts of your story — your timeline, your characters, your worldbuilding rules, your plot logic — and delivers a pass or fail verdict with detailed reasoning.
Think of it as a continuity editor who has memorized every detail of your book. Did your protagonist have blue eyes in chapter two and brown eyes in chapter nineteen? Did the sun set twice on the same day? Did a character reference an event that has not happened yet? Did you establish that magic requires a spoken incantation in book one but have a character cast silently in book three?
These are the mistakes that destroy reader trust. A single plot hole in a published novel generates one-star reviews. Readers who catch contradictions stop suspending disbelief — and they never get it back.
Human editors catch some of these issues, but they are working from memory across hundreds of pages. The scene and canon audit forgets nothing. It cross-references every fact, every timeline event, every character detail, every worldbuilding rule — and flags every contradiction it finds.
Unresolved plot threads, contradictory events, actions that violate established cause-and-effect, and logical impossibilities. Every plot hole is identified with the exact scenes involved and an explanation of the contradiction.
Event ordering, date consistency, travel time feasibility, and temporal logic. If your character is in Paris on Monday and Tokyo on Tuesday without air travel, the audit catches it. Tracks day/night cycles, seasons, and elapsed time.
Tracks character development across every scene. Catches personality regressions, knowledge contradictions (a character knowing something they should not), and motivation shifts that are not supported by events in the story.
Each character's speech patterns, vocabulary, and mannerisms are profiled and monitored. If your street-smart thief suddenly speaks like a professor, or your reserved introvert delivers a rousing monologue without narrative justification, it is flagged.
Magic systems, technology rules, geography, political structures, cultural norms — every worldbuilding detail established in your manuscript is tracked. Contradictions between what you established and what you later wrote are caught automatically.
Every issue is ranked: critical (plot-breaking, readers will definitely notice), major (significant inconsistency that damages credibility), or minor (small continuity detail). Fix the critical issues first, address the rest at your own pace.

The audit reads your entire manuscript and builds a comprehensive canon database — every character detail, timeline event, worldbuilding rule, and plot point. This becomes the source of truth for your story.
Each scene is analyzed against the canon database. The AI checks for contradictions, timeline errors, character inconsistencies, and lore violations. Every scene receives a pass or fail verdict with detailed reasoning.
Issues are presented ranked by severity with exact scene locations, the conflicting facts, and clear explanations. You decide what to fix and what to keep — the audit gives you the information, not the mandate.
Readers are remarkably good at tracking story details — often better than the authors who wrote them. They remember that the protagonist's sister was mentioned as younger in chapter three but older in chapter fifteen. They notice when a character who was established as left-handed suddenly draws a sword with their right. They catch when a locked room suddenly has an unlocked window that was never mentioned before.
Every inconsistency is a crack in your story's foundation. One or two might go unnoticed. But they accumulate. By the time a reader has found three or four contradictions, they have mentally downgraded your book from "immersive" to "sloppy." They start reading critically instead of reading for pleasure. And critical readers leave critical reviews.
The worst part is that these mistakes are entirely preventable. They exist because no human can hold 100,000 words of detail in their head simultaneously. You wrote chapter three six months ago. Of course you forgot what you established about the sister's age. The scene and canon audit does not forget. It checks everything against everything, every time.
For series writers, consistency is exponentially harder. Every new book adds thousands of facts that must remain compatible with everything that came before. Character histories, world rules, political alliances, magic limitations, geography — all of it compounds.
The scene and canon audit works across multiple books in a series. It builds a cumulative canon database that grows with each volume, ensuring that book four does not contradict a detail established in book one that you wrote two years ago. Series-level contradictions are flagged with cross-references to the original source scene.
Every fact established in any book in your series is tracked and enforced across all subsequent books. Character details, world rules, and timeline events are cross-referenced automatically between volumes.
The canon database grows with each book you add. New details are checked against the entire series history, catching contradictions that span hundreds of thousands of words and years of writing.
A scene and canon audit is an AI-powered deep analysis that examines every scene in your manuscript for plot holes, timeline errors, character inconsistencies, and lore contradictions. Each scene receives a pass or fail verdict with detailed reasoning, and issues are ranked by severity so you can fix the most damaging problems first.
Yes. The scene and canon audit works across multiple books in a series, tracking character arcs, timeline events, worldbuilding rules, and lore details established in earlier volumes. It catches cross-book contradictions that are nearly impossible to find manually.
Every issue found is assigned a severity level: critical (plot-breaking contradictions), major (noticeable inconsistencies readers will catch), and minor (small continuity details). This lets you prioritize fixes and focus on the problems that would actually damage the reading experience.
The scene and canon audit is available on Author tier and above. It is one of ProseEngine's most powerful analysis features, designed for writers who need their manuscripts to be internally consistent before sending to editors or publishing.
Every plot hole the audit catches is one fewer reason for a reader to leave a one-star review.
