The value of a good prompt

"AI has leveled the playing field. Anyone can ship their ideas. The barrier to entry is lower than ever. But everyone has access to the same models. Your prompt is the only thing that sets your output apart from the rest. Get it right, and the AI understands exactly what you need. Get it wrong, and you're just another in the crowd. The quality of your input dictates the quality of your outcome. Pronto gives you the tools to get it right.
