MasterMyPrompt doesn’t give you another prompt library—it turns your rough idea into a structured, model-optimized prompt in one step. You describe what you want; we add personas, context, and constraints and tailor the output for ChatGPT, Claude, Gemini, Perplexity, or Grok. No templates to browse, no prompt-engineering course required, just paste your thought and get a pro-grade prompt you can use immediately.

Hey Product Hunt — I'm Prajit, maker of MasterMyPrompt.
I built this because I kept having the same problem: I knew what we wanted from ChatGPT or Claude, but our prompts were too vague and the results were hit-or-miss. So I have made a tool that takes your rough idea and turns it into a structured, model-optimized prompt in one click personas, context, and constraints included.
No prompt-engineering course required. You can try it free in the browser.
Would love to hear what you’d use it for or what you’d want it to do next. Ask me anything.
