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, places, timeline, and world rules, then checks new pages against it. It reads what you wrote; it does not write your book.

For solo writers, for writers’ rooms working on scripts (.fountain), and for editorial teams.

Example · sample manuscriptThe Vanishing Hour

Chapter 23 says right forearm. Chapter 7 says left.

Chapter 7, page 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.

New draft, Chapter 23

Harrison hauled the crate one-handed, wincing as the old scar on his right forearm pulled tight.

See the Story Bible entry it comes from

Story Bible · Harrison

Scar on the left arm, elbow to wrist

From Chapter 7, page 89, word for word:

“scar tissue that ran from his left elbow to his wrist”

Military service · not stated

Chapter 7 mentions “Fallujah”, but no sentence says he served. PlotLens leaves it blank for you to settle instead of guessing.

Three steps

PlotLens doesn't edit your manuscript. The Word add-in changes your text only after you confirm an update.

  1. Add your manuscript

    One file or one per part. Each file becomes a document in your book.

  2. PlotLens reads it and keeps story notes

    Who and what your book establishes, linked to the passage where PlotLens can find it.

  3. Check it and settle questions

    Passages that disagree with what the book established become questions for you to answer.

What PlotLens does with a manuscript

Upload a manuscript. Get a story bible.

PlotLens reads your manuscript or script and keeps notes on its characters, places, timeline events, and world rules, each searchable and linked to the passage it came from. It reads. It does not write.

  • Upload .docx, .pdf, .md, .txt, .rtf, .epub, or .fountain. Scrivener projects work through the Companion app (beta, Plus and above).

Fix continuity breaks before readers hit them.

Upload the manuscript you already have. PlotLens builds your Story Bible from it, then compares new writing against the facts it has read and points to the conflict when it finds one. You keep the desk.

  • Checks as you write are on Plus and above.

When we flag a break, you can open the source.

Each finding points back to the line in your draft and the passage behind it, so you can check it yourself. When PlotLens can’t point to the exact passage, it says so instead of showing a citation.

  • On a team, owners, admins, editors, and viewers share one Story Bible.
Worked illustrationPublic-domain text, not a PlotLens run
A Study in Scarlet, Arthur Conan Doyle

There I was struck on the shoulder by a Jezail bullet, which shattered the bone and grazed the subclavian artery.

Story note Watson’s wound is in the shoulder.

The Sign of the Four, Arthur Conan Doyle

I made no remark, however, but sat nursing my wounded leg. I had a Jezail bullet through it some time before, and, though it did not prevent me from walking, it ached wearily at every change of the weather.

Story note Watson’s wound is in the leg.

QuestionWound location

These two passages place the same wound in different parts of the body. Which is right?

Two passages from different Sherlock Holmes novels, each describing Dr. Watson’s Jezail bullet wound, one in the shoulder and one in the leg, raised as a single question.

Made for the way you write

Find the story details you need

Series writers juggle characters, locations, and timeline threads across books. PlotLens builds a reference from your manuscripts and surfaces possible conflicts for you to review.

  • Review characters, aliases, and relationships across your uploaded books
  • Check possible attribute, timeline, and relationship conflicts
  • Extracted facts link back to the page and passage they came from, when a clean span is available

Sarah burned the letter without opening it.

In these examples, a dashed row is something the manuscript does not state. PlotLens lists it for you to decide instead of guessing.

Your pages, checked against your pages.
