Just Chat delivers a complete self-hosted chat interface for interacting with large language models.

The platform enables attachments, letting users upload documents for context-aware Q&A. Plugin integration allows external tool calls such as web search, calculations, or database queries. Developers can design custom prompt templates, control system messages, and switch between models seamlessly. The UI is built using React and Node.js, offering a responsive web experience on desktop and mobile. With its modular plugin system, users can add or remove features easily, tailoring Just Chat to customer support bots, research assistants, content generators, or educational tutors.
