This tool is designed specifically for prompt engineering showcases.

Best practice workflow:
1. Generate image with basic prompt in Midjourney/DALL-E
2. Generate image with refined/advanced prompt
3. Upload both to comparison tool
4. Add both prompts in "AI Prompt" field (tool displays them)

Prompt display tips:

This helps your audience learn from your prompt engineering skills!
