## What it is
Chat Copilot is a sample application from Microsoft for building your own LLM-powered chat copilot, built on Semantic Kernel. It consists of a React frontend, a .NET web API backend, and a .NET worker service for semantic memory processing, and is explicitly intended for education rather than production use.

## Use cases
- build a custom chatgpt-like assistant
- learn how to integrate llms into a web app
- example of semantic kernel usage
- prototype an ai chat copilot with memory
- deploy a chat app to azure openai
- understand rag and semantic memory pipelines

## When to choose
- you want a reference implementation for building an LLM chat app with Semantic Kernel
- you are learning how chat copilots with semantic memory are architected
- you want a starting point to customize into your own assistant

## When to avoid
- you need a production-ready, hardened chat application
- you want a turnkey product rather than a sample to study and modify
- you do not want to incur OpenAI/Azure OpenAI token costs per interaction
