Just Chat delivers a complete self-hosted chat interface for interacting with large language models. By inputting API keys for providers like OpenAI, Anthropic, or Hugging Face, users can start multi-turn conversations with memory support. 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.

SwiftAgent offers a robust toolkit for constructing intelligent agents by integrating OpenAI's models directly in Swift. Developers can declare custom actions and external tools, which agents invoke based on user queries. The framework maintains conversational memory, enabling agents to reference past interactions. It supports prompt templating and dynamic context injection, facilitating multi-turn dialogues and decision logic. SwiftAgent's async API works seamlessly with Swift concurrency, making it ideal for iOS, macOS, or server-side environments. By abstracting model calls, memory storage, and pipeline orchestration, SwiftAgent empowers teams to prototype and deploy conversational assistants, chatbots, or automation agents quickly within Swift projects.
