Ever noticed how AI image generators create wildly different styles each time? In this video, I'll show you how to solve that problem using meta prompting and JSON structures to generate consistently styled images for your apps.

What You'll Learn:

- Meta Prompting: A technique to get LLMs to produce more consistent outputs
- JSON Structures: The format LLMs love for creating repeatable results
- Practical Application: Generate consistent images for your app landing pages

Step-by-Step Tutorial:

1. Use Google Gemini (free!) to analyze your reference image
2. Generate a JSON prompt template that captures style, lighting, color, and design
3. Modify the template to create new images in the exact same style
4. Apply this to your Lovable app projects

No coding required—just copy, paste, and tweak the JSON fields to get exactly what you need.

Next Up: In the next video, I'll show you how to insert these generated images into your Lovable app.

Prompt to use for Gemini's image generation:

"Create a meta prompt for me to use on Gemini, the form of a JSON output. I want to use this JSON output to create images of other images in a similar, consistent art and geometric style, simply by changing certain key values within the JSON."
