## Definition

Semantic memory is compact stored information about important facts, preferences, or events that can be retrieved later because of meaning rather than raw message order.

## Quick Answer

In AI roleplay, semantic memory is useful when the app needs to preserve names, promises, relationship changes, locations, secrets, and unresolved plot points without replaying the whole transcript.

## Plain Language

It is memory as meaning, not memory as every sentence. The app tries to save what matters for the next scene.

## Why It Matters

Semantic-memory terms connect privacy, memory quality, long roleplay, and paid-tier decisions.

## OnlyKin Angle

OnlyKin should explain semantic memory as compact continuity, while being clear that memory also affects privacy expectations.
