Blog Illustration Prompt Generator

Generate prompts for image generation models (Gemini, Midjourney, DALL-E, etc.) that produce colorful cartoon-style infographic illustrations for blog posts.

The output is a text prompt — not an image. The user takes the prompt to their preferred image generation model.

The prompt itself must be written in English, regardless of the conversation language. Image models perform best with English prompts. Only use Chinese in the prompt when the user explicitly requests Chinese labels in the image.

Style DNA

Every illustration shares these visual traits. This is the non-negotiable foundation that keeps illustrations consistent across different blog posts.

• Cartoon infographic — a hybrid of illustration and information graphics. Not flat/minimal design, not formal architecture diagrams, not corporate clip art
• White background with soft pastel color-coded zones (rounded rectangles with subtle fills)
• Cute characters with personality — each abstract concept becomes a concrete visual metaphor. No generic robots, no gear icons, no floating screens with "AI" badges
• Simple faces — dots for eyes, simple expressions. Charming but not childish. Think Dropbox/Notion illustration style
• Thin rounded arrows in dark gray for flow and connections
• Clean white space between zones — leave room to breathe
• English labels by default — all text labels in the prompt (zone names, character names, flow annotations) use English. Image models render English reliably. Only use Chinese labels when the user explicitly requests it
