What is a world book?
A world book is a dynamic memory system. Instead of putting all lore into the system prompt, you create entries that are injected when matching keywords appear in the conversation.
This keeps the context cleaner and helps the model focus on relevant facts.
Create or import a world book
New or imported books
Open the World Book area to create a new book, or import a compatible .json world book file.
Entries
Each entry usually contains:
- Trigger keys: words or phrases that activate the entry.
- Content: the lore text inserted into context.
- Order or weight: how entries are prioritized.
- Enabled state: whether the entry participates in matching.
Bind a world book to a chat
Open Chat Settings for the relevant character or conversation and choose the world book you want active. Binding ensures the entries are considered during that chat.
FAQ
Why did my keyword not trigger?
Check whether the text in chat exactly matches the trigger key, whether the entry is enabled, and whether the world book is bound to the chat.
Can one character use multiple world books?
Depending on the app version and workflow, you may be able to combine or switch world books. Keep entries focused to avoid context overload.
Why are imported entries blank?
The source file may use fields Tavern Studio does not support yet, or the export may be incomplete.
