Glossary Builder reads your manuscript and collects the invented words, titles, and terms your readers need defined.

The Appendix Readers Flip to and You Never Built
Your world has ranks, currencies, honorifics, magic terminology, and six words you invented for things that do not exist. You know what all of them mean. Your reader is on page 140 trying to remember whether a Vashti outranks a Serrin.
Readers who lose track of your vocabulary stop trusting the book. They skim past terms rather than pausing, and skimming is how a reader talks themselves into putting a novel down.
Glossary Builder reads your manuscript and assembles the glossary. Upload the book and get the terms with definitions drawn from how you used them.
Upload your manuscript, and you get:
- The invented terms, titles, ranks, and proper nouns your story uses
- A definition for each, built from context across the whole book
- Terms grouped so related vocabulary sits together
- A spoiler setting, so you can produce a front-matter version that gives nothing away
- The words you used inconsistently, spelled or capitalized two ways
Use It To
- Build the appendix your epic fantasy has needed since draft one
- Catch a term you spelled two ways across a long manuscript
- Give an audiobook narrator the vocabulary list they will ask for
- Hand a translator the terms that need consistent handling
- Check whether you introduced a word before you first leaned on it
- Create a spoiler-free glossary for the front of the book
- Give your copy editor a style sheet instead of making them build one
- Seed a wiki or a reader-facing world guide
Why It Works
Invented vocabulary is a debt. Every term you coin has to be introduced, reinforced, and kept consistent, and the cost lands on the reader when you skip a step. Books that fail at this get reviews that say the world was confusing, which readers mean literally.
A glossary pays down the debt in two directions. It gives readers somewhere to look, and building it shows you which words you never defined on the page at all. A term that needs a glossary entry to be comprehensible is usually a term that needed one more sentence in chapter two.
The spoiler setting matters more than it sounds. A front-matter glossary that reveals a character's true title spoils a reveal 200 pages early, which is why many authors skip the appendix rather than risk it.
Consistency is the quieter win. Coined words drift over a long draft, picking up an extra letter or losing a capital, and spellcheck will never flag a word it has never seen.

FAQ
- What is Glossary Builder? A Patron Toolbox tool that reads your uploaded manuscript and returns a glossary of the invented terms, titles, and proper nouns it contains, with definitions drawn from your text.
- What is the spoilers setting for? It controls whether definitions can reference later events. Choose the spoiler-free version for a glossary at the front of the book, and the full version for your own reference or a back-matter appendix.
- Do readers use glossaries? Readers of secondary-world fantasy and hard science fiction do, and they say so in reviews when one is missing. In other genres a glossary is more often a tool for you and your production team than for readers.
- Will it include ordinary words? It targets vocabulary specific to your book. Archaic and technical real words often earn a place too, since a reader who does not know them is equally stuck.
- Can I refine the entries? Yes. Continue the conversation and ask for shorter definitions, a different grouping, or more detail on a term.
- How much does it cost? Glossary Builder is available to all Novel Marketing patrons at the $10/month level and above. You can become a patron at patreon.com/novelmarketing.
