About

ChatKit is a conversational AI toolkit that lets developers embed and manage chat agents across apps and websites. It provides capabilities such as chatting over external documents, text-to-speech, prompt templates, and shortcut triggers. Users can operate ChatKit either using their own OpenAI API key (paying according to OpenAI’s token pricing) or via ChatKit’s credit system (which requires a ChatKit license). ChatKit supports integrations with diverse model backends (including OpenAI, Azure OpenAI, Google Gemini, Ollama) and routing frameworks (e.g., OpenRouter). Feature offerings include cloud sync, team collaboration, web access, launcher widgets, shortcuts, and structured conversation flows over documents. In sum, ChatKit simplifies deploying intelligent chat agents without building the full chat infrastructure from scratch.

About

It offers 12 modes of operation, including chat, chat with files, realtime + audio, research, completion, image and video generation, vision, assistants, experts, computer use, agents, and autonomous mode. Users can chat with their own files and data using integrated LlamaIndex support. PyGPT includes built-in vector database support, automated files and data embedding, full conversation context, short- and long-term memory, internet access through Google, Microsoft Bing, and DuckDuckGo, plus speech synthesis and recognition.
