I had no coding background, no intention to go all the way. But once I started designing how prompt engineering should feel — modular, testable, visual — I couldn’t stop until it was real. As AI systems evolve rapidly, prompts are becoming the new software. Yet, tools for serious prompt work remain either too simple or too technical. I wanted to change that — to create the VS Code for prompt engineers. What…
