+
+
+Using the Dapr conversation API, you can reduce the complexity of interacting with Large Language Models (LLMs) and enable critical performance and security functionality with features like prompt caching and personally identifiable information (PII) data obfuscation.
+
+## Features
+
+### Prompt caching
+
+To significantly reduce latency and cost, frequent prompts are stored in a cache to be reused, instead of reprocessing the information for every new request. Prompt caching optimizes performance by storing and reusing prompts that are often repeated across multiple API calls.
+
+### Personally identifiable information (PII) obfuscation
+
+The PII obfuscation feature identifies and removes any PII from a conversation response. This feature protects your privacy by eliminating sensitive details like names, addresses, phone numbers, or other details that could be used to identify an individual.

+Let's get started using the [conversation API]({{< ref conversation-overview.md >}}). In this guide, you'll learn how to:

+- Set up one of the available Dapr components (echo) that work with the conversation API.   
+- Add the conversation client to your application.
