Hey Product Hunt! I'm Rodrigo, solo founder of PromptArch. I built this because I kept watching the same pattern, people spending 20 minutes staring at a blank text box or iterating 15 times in a single conversation, trying to write a system prompt or cursor rule, then getting mediocre results because they forgot to specify constraints, didn't structure it for their target model, or just didn't know what questions to ask themselves. The idea behind PromptArch is simple: what if the tool asked YOU the right questions first? Instead of a blank editor, you pick a domain (software dev, autonomous agents, marketing, etc.), walk through a guided wizard, and get a prompt that's optimized for your specific model, with a quality score that tells you exactly where it's strong and where to improve. The part I'm most excited about is the Context Engineering Studio. As the field moves from simple prompts to system prompts, CLAUDE.md files, cursor rules, and agent configs, there's no structured tooling for any of it. Everyone's copying from GitHub gists or writing from scratch. This domain is built specifically for those artifacts. Would love your feedback, especially on which domains or sub-types you'd want to see next. Try it for free, no card required. No Suscription.
