Best Practices

Emoji Design

• Simplicity: Keep designs simple and readable at small sizes
• Bold Outlines: Use thick outlines for clarity
• Limited Colors: Stick to 3-5 colors per emoji
• Expressions: Exaggerate facial expressions for impact
• Consistency: Maintain style across a pack

Platform Optimization

• Transparent Backgrounds: Always use for best compatibility
• Square Format: Most platforms expect 1:1 aspect ratio
• File Size: Keep under 256KB for animated emoji
• Test Small: Preview at 32x32 to ensure readability

Animation Tips

• Loop Seamlessly: Ensure animations loop smoothly
• Keep it Short: 1-3 seconds is ideal
• Simple Motion: Single motion reads better than complex
• Frame Rate: 10-15 FPS works well for emoji

Prompt Tips for Emoji

When creating emoji, include these details:

1. Style: Cartoon, kawaii, flat design, 3D, etc.
2. Expression/Emotion: What feeling should it convey?
3. Size: Specify output dimensions
4. Background: Request transparent background
5. Platform: Mention target platform for optimization
6. Consistency: Reference previous generations for packs

Example Prompt Structure

"Create a [style] emoji of [subject/expression].
[Visual details and characteristics].
Output at [size] with transparent background.
Target platform: [Slack/Discord/WhatsApp/etc.]"

Mode Selection

Ask your users before generating:

"Do you want fast & cheap, or high quality?"

Multi-Turn Pack Creation

Use session_id to build cohesive emoji packs:

# Start with character design
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Design a cute mascot character for my emoji pack - a happy cloud with a face",
    "session_id": "cloud-emoji-project"
  }'

# Add expressions
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Create this cloud with a rainy sad expression",
    "session_id": "cloud-emoji-project"
  }'

# Continue building the pack
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Now make a sunny happy version with rainbow",
    "session_id": "cloud-emoji-project"
  }'

Batch Generation for Packs

Generate complete packs efficiently:

# Generate full expression set in one request
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Create a complete emoji pack of 8 food emoji: pizza slice, hamburger, sushi, taco, ice cream cone, donut, coffee cup, and avocado. All in the same cute kawaii style with happy faces, consistent line weight and color palette. 128x128 each with transparent backgrounds.",
