## Definition

World info is a roleplay memory system that stores background facts and inserts matching entries into the prompt when the current chat context makes them relevant.

## Quick Answer

World info and lorebooks solve the same broad problem: they keep large fictional settings available without permanently spending context on every fact.

## Plain Language

If the scene mentions a city, faction, spell, family, or object, the world-info entry for that thing can be added for the model to read.

## Why It Matters

World-info pages help users moving from advanced tools understand which concepts matter in a simpler web character-chat app.

## OnlyKin Angle

OnlyKin can present worldbuilding as guided structure instead of making setup feel like a configuration project.
