Long books drift. Serial writers on Xiaohongshu keep a three-point checklist before every upload: is the timeline consistent, are relationships the same, and who holds each key prop. Done by hand over forty chapters, it is the first thing to slip.

The problem

In our demo novel, The Salt Road, Mara gives her brass compass to Tomas in chapter 2, and the rockfall takes both. In chapter 4 she takes the compass out of her pocket, and Tomas laughs from the back of the cart. Each chapter reads fine alone. Only the whole book is wrong.

How Scenaloom handles it

  1. Write the facts that change in the story bible's Changes over time: Mara is 17, then 18 from chapter 3; Tomas dies in chapter 2. The AI reads only the facts true at the chapter it is working on.
  2. Open AI advisors and run the continuity check. The price shows first, in chats from your plan, and a stopped or failed read costs nothing.
  3. Each finding names both places with a quote, so one click takes you to the line to fix. A dead character who speaks, and a prop used after it was lost or broken, are caught in code as well as by the read.

Changes over time: a fact holds from the chapter you choose, so an age or a death is never a contradiction.
Each finding links the chapter where the fact was set and the chapter that contradicts it.

Props and who holds them

The same read keeps a table of key objects: who last had each one, in what state, and where it was last seen. It is the third item on that checklist, kept for you.

The Props and who has them table: brass compass held by Mara, iron key held by Mara, tin box held by Mara, with state and last chapter seen
Props and who has them, from the same read.

The result

Two real slips found in four chapters, each with a link to the line. The fix is still yours: the check reports, it never rewrites. Longer books are read in parts, each priced before it runs, and a part that has not changed is not read again.

Facts you add in Changes over time are never reported as contradictions: an age that changes in chapter 3 is the story, not a mistake.

Questions

Does it work for a series of scripts too?

Yes. In a script project the check reads the episodes in order, and Changes over time can start from an episode or a scene.

What does a check cost?

It is priced in chats from your plan's monthly allowance and shown before it runs. A read you stop, or one that fails, is not charged.

Will it change my text?

No. It lists findings with links; you decide what to change.
