About OpenChat

OpenChat is an open-source, everyday user chatbot console designed to simplify the utilization of large language models. It provides a two-step setup process to create a comprehensive chatbot console that serves as a central hub for managing multiple customized chatbots. Currently supporting GPT models (GPT-3 and GPT-4 if available), OpenChat allows users to create unlimited local chatbots, customize them using PDF files, websites, and soon integrations with platforms like Notion, Confluence, and Office 365. Each chatbot has unlimited memory capacity, enabling seamless interaction with large files such as a 400-page PDF. Additionally, OpenChat supports embedding chatbots as widgets on websites or internal company tools, and using an entire codebase as a data source for pair programming mode. The project is open-source and free, but the repository was archived on January 5, 2025, and is now read-only.
