Input Tips

Short prompts work ("AI trends 2026") but detailed structured text produces better results
Insert image URLs directly in inputText where you want them placed
Use
```
\n---\n
```
in inputText to force card breaks (set
```
--card-split inputTextBreaks
```
)
To use only your images (no AI-generated ones), set
```
--image-source noImages
```
JSON-escape special characters in inputText

Credit Costs

Cards: 1-5 credits each
AI images: 2 credits (basic) to 125 credits (ultra) per image
Example: 10-card deck with basic AI images ≈ 20-60 credits
