Promptheus

Promptheus is a prompt refinement and optimization tool for LLM (Large Language Model) prompts, designed for developers, data scientists, and prompt engineers. It works as both a command-line tool and a web interface, enabling users to iteratively improve prompts via adaptive questioning and interactive sessions. Promptheus supports multiple AI providers (including OpenAI, Google, Anthropic, Groq, Qwen, Zhipu GLM, and OpenRouter), tracks session history, integrates into Unix pipelines, and can be used as a Python library or through its Model Context Protocol (MCP) server for integration with MCP-compatible clients.
