AI Prompt Mastery Pack - 100+ reusable prompts for everyday AI workflows

I built this after repeatedly writing similar prompts for code reviews, API design, SEO content, marketing copy, UI/UX feedback, and data analysis. The goal is to validate whether a focused, practical prompt library is more useful than another huge generic prompt dump. I’d love feedback on the positioning, pricing, and which niche I should target first: developers, marketers, creators, or founders.
