The Process

Step 1: Understand the Content

Gather these inputs:

• Post title: What's the article called?
• Summary: 1-2 sentence description of the content
• Tone: Technical, reflective, playful, personal?
• Key concept: What's the ONE main idea to visualize?

Step 2: Select the Mode

Match content type to illustration mode:

Step 3: Identify the Visual Metaphor

The illustration should represent the concept visually, not literally.

Good metaphors (from published examples):

• AI processing → geometric shapes flowing into brain network
• Time/​timestamps → melting clock with butterflies
• Building something → puzzle pieces forming a path
• Data cultivation → garden with floating data cards
• Orchestrating AI → conductor's baton with flowing lines

Bad approaches:

• Generic person at laptop
• Literal representation of the topic
• Stock illustration style

Step 4: Build the Prompt

Use the template for your selected mode from illustration-style-guide.md.

Template structure:

[Style specification]
[Background color]
[Subject/​metaphor description]
[Color specifications with hex codes]
[Composition notes]
[Texture/​style notes]
[Negative constraints]

Step 5: Add Negative Prompts

Always append these exclusions:

Universal (always include):

no text, no words, no labels, no watermarks, no signatures, no logos

Style protection:

no photorealism, no 3D render, no harsh gradients, no glossy surfaces
no stock illustration style, no corporate clip art

Quality:

no blur, no artifacts, no low resolution
