  • Specify tone (teasing, cruel, playful)
  • Include content focus (body parts, actions, emotions)
  • Mention POV (first person, second person)
  • Suggest caption length (short/punchy vs detailed)
Example Custom Prompt 
Write as a cruel goddess who mocks the viewer for being 
weak. Use second person POV. Focus on humiliation and 
denial. Keep it under 100 characters. Playful but mean tone.

​
Styling Tips

For maximum readability:
  • Use White text on dark images
  • Use Black text on light images
  • Enable Background for busy/complex images
  • Enable Text Shadow for extra contrast
  • Set background opacity to 40-60%
Match style to content:
  • Impact/Arial Black: Bold, attention-grabbing (memes)
  • Georgia: Elegant, sophisticated (artsy images)
  • Inter: Clean, modern (default choice)
  • Gold color: Luxurious, dominant energy
  • Pink/Purple: Playful, bratty themes
Text placement strategy:
  • Left align: Better for longer captions
  • Center align: Better for short captions
  • Bottom placement: Classic meme style
  • Larger font (48-72px): Short, punchy captions
  • Smaller font (18-32px): Detailed, multi-line captions
