Revolutionizing Ad Creation with Generative AI: My Capstone Project Journey

Introduction

In today’s fast-paced digital marketing world, businesses need high-quality, engaging, and scalable ad creatives—but crafting them manually is time-consuming and resource-intensive.

For my capstone project, I built GenAI Ad Creator, a Generative AI-powered tool that automates the generation of structured ad content (titles, descriptions, keywords, and image prompts) from simple product descriptions.

This blog post covers:

The Problem: Why Manual Ad Creation Falls Short

Creating effective ad campaigns requires:

• Multiple variations of ad copy for A/B testing

• SEO-optimized keywords to improve visibility

• Compelling visuals that resonate with audiences

• Brand consistency across platforms

Doing this manually is:

⏳ Slow – Writing and designing take hours.

🎨 Skill-dependent – Not everyone is a copywriting expert.

🔄 Inconsistent – Maintaining brand voice across ads is tough.

What if AI could automate this?

The Solution: AI-Powered Structured Ad Generation

My GenAI Ad Creator solves this by:

1. Structured JSON Output for Easy Integration

• Input: A simple product name and description (e.g., "Premium wireless earbuds with ANC and 30-hour battery").

• Output: A machine-readable JSON with:

{
  "ad_title": "...",
  "ad_body": "...",
  "meta_description": "...",
  "keywords": [...],
  "image_prompt": "...",
  "target_audience": "..."
}

• Why it matters: This structured format integrates seamlessly with ad platforms (Google Ads, Facebook Ads).

2. Few-Shot Prompting for High-Quality Output

The AI is trained with real-world ad examples to ensure:

• Brand-aligned messaging

• Engaging & conversion-focused copy

• Avoids generic outputs

3. Context-Aware Generation (RAG-like Approach)

• The AI analyzes product descriptions to generate relevant, feature-specific ads.

• Ensures ads accurately reflect product benefits.

The Kaggle Notebook demonstrates:

1. Prompt Engineering for Structured Output

The AI is instructed to generate JSON-formatted ads with:

• Catchy headlines

• Benefit-driven descriptions

• SEO-friendly keywords

• Detailed image prompts for AI art generators (DALL·E, Stable Diffusion)

2. Google’s Gemini for Ad Copy Generation

• Uses google-genai sdk to produce high-quality text.

• Just input Product name and Description

3. AI-Generated Images

• Generates text prompts for visuals (compatible with Gemini, ChatGPT, DALL·E, Midjourney).

• Direct image generation via Gemini vision models.
