## Overview

Groq Chatbot is a Streamlit conversational app. The user selects a model, persona, and memory window, submits a message, and receives a response from a Groq model through a LangChain conversation chain. Session state holds displayed chat history and timing; prior messages are replayed into the memory buffer on reruns. The README also documents model and persona choices, chat statistics, and clear/new-topic actions. All implementation is in app.py, so subsystem paths repeat; internal wiring reflects the sampled source.

Main entry points: [`app.py`](https://github.com/arya-io/groq-chatbot/blob/main/app.py) (Conversation chain)
