ChatGPT Lite is a lightweight ChatGPT web interface developed using Next.js and the OpenAI Chat API. It's compatible with both OpenAI and Azure OpenAI accounts.

• Deploy a custom ChatGPT web interface that supports markdown, prompt storage, and multi-person chats.
• Create a private, web-based ChatGPT for use among friends without sharing your API key.
• Clear and expandable codebase, ideal as a starting point for your next AI Next.js project.
