Featured Project

Image Prompt Optimizer

An AI-powered image generation tool that solves the common problem of prompt iteration—users typically adjust prompts 5+ times before getting their desired result. Uses GPT-4o-mini to analyze and optimize prompts upfront with intelligent recommendations. Users select or customize descriptions, which are formatted as JSON and sent to GPT Image for precise, high-quality results on the first try.
