User Interface & Chat Characters

Light & Dark Modes From the Start

This is the basic user interface for Rook. It is designed to be a customizable but simple AI chat client for OpenAI & other servers running compatible chat LLM APIs.

Originally the motivation for developing the program was to have a simple place to test out fun AI personality characters while using LM Studio as the LLM server.
