I built Prompty because I got tired of watching myself and people struggle with prompt engineering. Not because we lack skill, but because remembering all the patterns-context windows, few-shot examples, output formatting, constraint definitions-takes mental bandwidth that could go toward actual problem-solving.

Give it a task description. It analyzes what you need, determines which variables matter (or you can specify them yourself), and generates an engineered prompt. No fluff. No guessing if you structured it right.

The app includes six pre-built templates: Customer Support Agent, Document Q&A System, Email Writer, Code Review Assistant, Math Tutor, and Text Summarizer. But the real power is custom task creation—describe what you're trying to do (sentiment analysis, content moderation, data extraction, whatever) and it builds the prompt structure for you.

Under the hood, it applies metaprompt engineering: the technique of using an LLM to write prompts for other LLMs. Think of it as compiler optimization for natural language. The patterns are consistent, repeatable, and grounded in what actually works.
