The story bible that builds itself — and flags the pages that break it.
Upload your manuscript and PlotLens builds a Story Bible of its characters, locations, timelines, and world rules, then checks new pages against it. It reads what you wrote; it does not write your book.

Sample project demo. PlotLens reads Chapter 7, where Harrison’s scar runs from his left elbow to his wrist, and cites that sentence in the Story Bible. It holds “military service” for review, because Chapter 7 mentions Fallujah but no sentence says he served. A Chapter 23 draft then puts the scar on his right forearm, and PlotLens asks which is right, with a link back to the Chapter 7 source.
Chapter 7 · p. 89
Harrison rolled up his sleeve, revealing the pale ridge of scar tissue that ran from his left elbow to his wrist. “Fallujah,” he said, as if that explained everything. And to Elena, it did.
Chapter 23 · new draft
Harrison hauled the crate one-handed, wincing as the old scar on his right forearm pulled tight.
Scar location — which is right?
Found in Ch. 23The draft puts the scar on his right forearm. Chapter 7 puts it on his left:
scar tissue that ran from his left elbow to his wrist
- Scar — left arm, elbow to wrist · Ch. 7, p. 89
- Military service — held for review. Chapter 7 mentions Fallujah; no sentence says he served.
- Chapter 23 draft contradicts the scar
Chapter 1 · Extraction
Upload a manuscript. Get a story bible.
PlotLens reads your manuscript — docx, pdf, even Scrivener exports — and extracts characters, locations, timeline events, and world rules into structured, searchable entity cards. That reading-not-writing posture is the category we call narrative intelligence.
- Characters with aliases, traits, and relationships
- Locations, timelines, objects, and world rules
- Supports .docx, .pdf, .md, .txt, .rtf, and .epub

Chapter 2 · Manuscript Check
Fix continuity breaks before readers hit them.
Upload the manuscript you already have. PlotLens builds your Story Bible from it, then Manuscript Check compares new writing against the facts we’ve examined and cites the conflict when it finds one. You keep the desk. We keep the canon trustworthy.
- Real-time validation as you write new chapters (Plus and above)
- Inline notes on entity mentions in the pages Manuscript Check runs
- Citations point to the source passage when a clean span is available
Elena drove across the causewayQuery A to Marrow Island with the headlights off.
This draft drives Elena across a causeway. Book 1 says the island has no road. Which is right?
Canon, Book 1, Ch. 4Marrow Island had no bridge and no road; the only way across was the ferry.
Chapter 3 · Provenance
When we flag a break, you can open the source.
Manuscript Check findings point back to the draft line and the Story Bible evidence behind the conflict — so you verify, not trust a summary. Items without a clean span stay in review, not dressed up as cited proof.
- Open the source passage for cited facts and findings when a span is available
- Owner, admin, editor, and viewer roles when you work as a team
- Author attribution on every document, validation, and rule

- Extracted facts link back to the page and passage they came from, when a clean span is available

Lore at scale, branching without breaking
Game narratives branch, and lore spans codexes, quest logs, and dialogue trees. PlotLens tracks the characters, places, and items in your documents and checks new writing against the canon you have established.
- Import documents in eight formats, from .docx and .pdf to .epub and .fountain
- Validate branching paths against established world rules
- Track NPC backstories, faction relationships, and item lore
- Sarah and James: in the same scene, Ch. 3, p. 47. That is co-occurrence only; no sentence states a relationship, so it is held for review.
- Sarah and Vera: held for review, no sentence states the relationship
- James and Vera: held for review, no sentence states the relationship
- James and Marcus: held for review, no sentence states the relationship
An automated first pass on continuity
Editors catch what writers miss — but manually checking continuity across a 400-page manuscript is brutal. PlotLens gives you an automated first pass so you can focus on craft.
- Run a full continuity report across a whole manuscript, on demand
- See contradictions with page-level citations for both sides
- Review entity cards across multiple authors in a shared project
