Feature · Stage 3, Check the book

Book two, checked against book one.

A reader who has waited a year for the sequel remembers how the first book spelled things. Scan each book and the screen holds them side by side: the names that drifted, the terms you established and then let go, and the style decisions the two volumes settle differently.

How it works

One book at a time, held against the last.

1

Scan a book, then add the next

The book on screen is one side of the comparison. Add the next one and it becomes the book being checked, with the one before it kept for comparison. Three books, four books, as many as you have.

2

The first comparison is included

Comparing against one earlier book costs no scan. It is read for its names, counts and spellings alone - no glossary, no exports, nothing kept - and every book after that uses one scan, which the button says before you choose a file.

3

Five things it sets against each other

Names close enough that one is likely a slip. Terms written another way. Terms an earlier book established and this one drops. Terms new to the series. And whether the books agree on spelling standard, quotation marks and house style.

FAQ

Questions about checking a series.

How is this different from comparing two drafts?

They answer opposite questions. Comparing drafts asks what changed in one book since its last version, where a near-match between two names means you renamed something and all is well. This asks whether two finished books agree, where the same near-match means one of them is misspelled. Same arithmetic underneath, opposite conclusion, so they are separate screens.

Does it cost a scan for every book?

Comparing against one earlier book is included with your scan. Every book after that uses one scan, and the control says so before you choose a file. When a pass runs out the option is greyed out with the reason on it, and the books already loaded stay while the tab is open.

Are my earlier books stored?

No. Nothing is stored, here or anywhere else in the tool. A book you add is read in memory and discarded, and the comparison lives in your browser tab - close it and the series goes with it. That is also why each book has to come from you.

Will it tell me a character's eyes changed colour?

No, and nothing here pretends otherwise. The scan is rule-based with no AI, so it reports what your books do with their own vocabulary: which names, which spellings, which terms, which style. Whether a fact contradicts one in an earlier volume is a judgement about meaning, and it stays yours.

A term is missing from book two. Is that a mistake?

Usually not, which is why the whole screen is marked for information rather than as a fix list. A subplot ends and its vocabulary ends with it. What the section does is make sure the decision was one you made: a term the earlier book used five times or more, then nothing, is worth a second look rather than an alarm.

The books use different spellings of a word. Which is right?

The screen does not say, because neither is wrong in itself. It reports that book one writes it one way and book two another, with the count for each, and you decide which the series keeps. Where a book has not settled a decision at all it says so rather than counting it as a disagreement.
