Meaning, not keywords
Entries surface by semantic similarity to the conversation. No trigger words to guess, no misfires when nobody says the magic term.
Write the locations, factions, and history once. Reverie pulls the right entry into the conversation by meaning — no keyword triggers to wire, in any language your players speak.
Why it matters
A character is only as deep as the world behind them. World books give that world a memory — and let it speak at the right moment.

Retrieval, not triggers
No activation keywords, no depth settings. Reverie matches the meaning of the moment to your entries, even across languages.

Lore that surfaces
Once royal, now disgraced; they trade loyalty for a chance at the throne they lost in the Sundering.
The fragile treaty House Vael secretly seeks to break.
Author it your way — or bring lore you already have.
Add entries for places, people, factions, items, and rules — or paste a blob and let AI split it into clean entries.
Bring a SillyTavern or character-card lorebook; its keys become recall hints, not brittle triggers.
Flag the handful of facts that should always be in context. Everything else waits until it's relevant.
Reverie embeds every entry and pulls the right ones into chat by meaning, within a smart token budget.
Make a book public and others can browse and attach it — auto-translated for their language.
What makes them different
The mechanics that usually trip people up are gone — Reverie handles them for you.
Entries surface by semantic similarity to the conversation. No trigger words to guess, no misfires when nobody says the magic term.
Multilingual embeddings match a line in one language to lore written in another. Shared books are translated for display, too.
Mark an entry canon (always present) or leave it when-relevant. No depth, order, or recursion to tune.
Browse public world books and attach them to your own characters in a click — like installing a mod for your world.
Import SillyTavern world info and character-book lore; we fold activation keys into recall hints.
A canon meter shows your always-on budget, and retrieval packs only what fits — context stays for the conversation.
