Prompt Lab - Design prompts that look goooood

PromptLab is a free prompt library that helps designers create professional AI design assets through battle-tested prompts for 3D renders, illustrations, and gradients. A focused project born from a simple frustration: spending hours tweaking prompts only to get generic, unusable AI outputs. After testing alot of prompt variations, I discovered that small changes in wording—specific rendering engines, art movements, and lighting terminology transform mediocre results into portfolio-quality work. I built PromptLab to make this knowledge accessible. The library updates weekly with new prompts and categories. It's also open to requests and submissions; if you've crafted prompts that consistently deliver great results, I'd love to feature them. Currently supporting ChatGPT (DALL-E 3), with plans to expand to Midjourney and other tools based on community feedback. This project reflects my belief that prompting is becoming an essential design skill, and the learning curve shouldn't require 200+ hours of trial and error. Check it out: promptlab.design
