About PromptMachine
PromptMachine is a precision console designed for drafting and optimizing structured prompts for artificial intelligence models. Rather than functioning as a conversational chatbot, it serves as an offline-first prompt engineering workbench distributed as a single-file Progressive Web App with zero user tracking. Users construct prompts by combining domain roles, operator action verbs, and custom settings, which are formatted into an Esperanto XML pivot grammar to maintain context and intent across different AI models.
