# SimKB

## Overview

SimKB is a HyperSkill feature that enables contextual question answering in simulations. AI Chat can answer questions based on information from the simulation, such as object locations or what the player is currently holding. Additionally, agents can automatically highlight objects in the scene to help the user.

SimKB also knows which state the learner is in. For example, if a learner is going through a lab and gets stuck at a step, they can ask a question and SimKB guides them based on where they are in the simulation.

## Usage

To use SimKB, you need access to [AI Chat](https://docs.siminsights.com/hyperskill-studio-authoring/ai-features/ai-chat). All large language models support this feature, so select the model of your choice. Then turn on **Enable SimKB** in the AI Chat edit panel.
