Best In-World Glossary Tools for Writers
If you're building a fantasy, science fiction or dystopian world, you have your own terms, titles, place names and maybe an invented language. Keeping a glossary is essential to use them consistently. This list compares four common ways to keep a fictional glossary.
How we evaluated
We looked at three criteria: (1) can you quickly find a term and see its meaning, (2) can you see where a term appears in the story and which records it relates to, (3) how much effort it takes to stay organized as the glossary grows. We don't list prices because they change over time.
1. A document (Word, Google Docs)
An alphabetical list of terms is the fastest start. It works for a few terms, but as the list grows you maintain the order by hand, and seeing where a term appears means scanning your texts.
2. A spreadsheet (Excel, Google Sheets)
Columns for term, meaning, origin and category make an orderly glossary that's easy to sort and filter. Long explanations and a term's relationship to characters or locations are hard to show in a spreadsheet, though.
3. General note apps (like Notion or Obsidian)
You can create a page per term and link it to other notes. Flexible, but you build the structure and linking yourself; there's no glossary view made for fictional worlds.
4. The yazar.io Glossary
In yazar.io's Glossary section each term is its own record with ready-made fields such as Category, Language and Meaning. When you type @Term in any text, the link is created automatically, and the term's page shows the records that mention it. Glossary records aren't subject to the 15-records-per-book limit on either plan. If you open your book as a Shareable Wiki, your glossary becomes a guide for your readers too. The trade-off: yazar.io is not a conlang tool; it doesn't generate conjugations or grammar rules.
Which approach suits an invented language best?
Any method works for a word list. If you're working out grammar in detail, keeping the rules in a separate document or a Lore record and the words as linked records in your glossary is a practical setup.
Can glossary terms link to characters and locations?
In yazar.io, yes. When you mention a term with @Term in a character's or location's description, the link shows up in both directions.
Is the Glossary on the free plan?
Yes, the Glossary is available on both plans and isn't subject to the 15-records-per-book limit.
