Mindset SDK 2 Overview

## What is the Mindset SDK 2?

The Mindset SDK 2 is our toolkit, simplifying the implementation of agents and UI components in your application to speed up time to market.

## Why use the SDK 2?

**Speed**: This approach avoids loading a large application in an iframe. Loading will feel instant, like a native component of your application.

**Modular Embedding**: It allows different Mindset features to be turned into components that can be placed in different parts of a product/ web page. For example, you can insert the Mindset chat widget or agent configuration anywhere in a HTML web-page.
