Ad Designer

Generate professional image ad creatives for Meta/social campaigns using AI image generation.

Model

Nano Banana Pro (gemini-3-pro-image-preview)

• State-of-the-art image generation and editing
• Good text rendering for ad copy
• Supports multiple aspect ratios

Prerequisites

• GEMINI_API_KEY in environment
• Brand guidelines (colors, fonts, voice) — ideally from /website_brand_analysis
• Creative brief (ad concept, copy, target audience)

Aspect Ratios

Always specify aspect ratio in the prompt. Common Meta ad formats:

Default to 1:1 unless brief specifies otherwise — it works everywhere.

Prompt Engineering

Critical Rules

1. Be explicit about exclusions:

   NO logos. NO brand names. NO company names. NO watermarks. NO additional text.
   

2. Specify exact text:

   The ONLY text on the image should be exactly: [your text here]
   

3. Keep prompts focused:

   • Don't overload with too many instructions
   • Separate layout from content from style

4. Include aspect ratio:

   Generate a square 1:1 image...
   

Prompt Template

Generate a [aspect ratio] image.

[Background/setting description]

[Text content - be explicit:]
The ONLY text should be exactly:
- Line 1: "[text]" in [color] [size]
- Line 2: "[text]" in [color] [size]

[Visual elements - icons, mockups, etc.]

Style: [clean/minimal/warm/professional/etc.]

NO logos. NO brand names. NO watermarks. NO additional elements.

Example Prompts

Price Anchor Ad:

Generate a square image. White background. Clean typography only, no decorations, no logos, no icons, no borders, no frames.

The ONLY text on the image should be exactly:
Line 1 (small gray): What companies pay €10,000 to train their teams...
Line 2 (large navy blue): You can learn for €249
Line 3 (small gray): AI Operator Course — 10 hours to AI proficiency.

The €249 should be in gold/yellow color. Nothing else. No brand names. No additional elements.

Native/Organic Creative:

Generate a square photograph of a notebook page. Warm lighting. Cream colored lined paper.

Handwritten text in black ink pen that says EXACTLY:
The AI tools dont matter.
The workflows do.
Most people chase the next tool.
Operators master the fundamentals.

Draw a hand-drawn red circle around the word workflows. Coffee cup visible at edge.

NO logos. NO brand names. NO watermarks. Just the notebook with handwritten text.

Tutorial Carousel Hook:

Generate a square image. Light cream/yellow background.

Navy blue bold text that says EXACTLY: How to summarize any meeting in 30 seconds with AI

Center the text. Include a simple video call icon below the text.

NO logos. NO brand names. NO company names. NO watermarks. Clean minimal design.

API Usage

curl -s "https://generativelanguage.googleapis.com/v1beta/models/gemini-3-pro-image-preview:generateContent?key=$GEMINI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "contents": [{
      "parts": [{
        "text": "YOUR_PROMPT_HERE"
      }]
    }],
    "generationConfig": {
      "responseModalities": ["image", "text"]
    }
  }' | jq -r '.candidates[0].content.parts[0].inlineData.data' | base64 -d > output.png

Workflow

1. Receive Brief

Get creative brief with:

• Ad concept (price anchor, native, tutorial, etc.)
• Exact copy/text
• Target aspect ratio
• Brand colors (if applicable)
• Reference images (if any)

2. Construct Prompt

Build prompt using template above. Key points:

• Start with aspect ratio
• Be explicit about exact text
• End with exclusions (NO logos, etc.)

3. Generate Image

Run API call, save to output folder:

~/clawd/output/{project}-{ad-type}-{version}.png

4. Review Before Sending ⚠️

ALWAYS review generated images before sending to user.

Check for:

• Text is correct (no garbled words)
• No hallucinated logos or brand names
• No unexpected elements
• Aspect ratio looks correct
• Overall quality is acceptable

Use the Read tool to view the image:

Read file_path=/path/to/image.png

5. Iterate if Needed

If image has issues:

• Simplify the prompt
• Be more explicit about exclusions
• Try regenerating (results vary)

6. Deliver

Send via message tool with descriptive caption:

message action=send filePath=/path/to/image.png caption="🎨 Ad Name (1:1) ✓ Reviewed"
