Bad visuals tank conversion; great visuals signal quality before anyone reads a word. But writing prompts that produce pro-quality output takes hours of trial and error. Visual Alchemy gives you 200+ production-tested AI image prompts organized by use case: Gumroad product covers, app store screenshots, LinkedIn/X carousels, SaaS UI mockups, presentation backgrounds, brand portraits, and abstract tech concepts. Works with Midjourney, DALL-E, and more.
