⚡ AI Copywriter Pro: Instant Ad Copy & CTA Generator

Transform product details into compelling marketing copy in seconds. This intelligent n8n workflow takes basic product information and generates professional ad copy with powerful calls-to-action using GPT-4, then distributes the results to your team via Slack or stores them in Airtable for future use.

🚀 How It Works

This streamlined 4-step automation delivers professional marketing copy instantly:

Step 1: Simple Form Input
Users submit basic product information through a clean web form - just product name and key features required.

Step 2: AI-Powered Generation
The workflow sends product details to GPT-4 with a specialized copywriting prompt that creates:

  • Compelling 2-sentence ad copy optimized for conversions
  • 3 powerful call-to-action phrases with different urgency levels
  • Professional tone tailored for marketing campaigns

Step 3: Structured Processing
The AI response is automatically parsed into clean, labeled fields ready for immediate use across marketing channels.

Step 4: Multi-Channel Distribution
Generated content is simultaneously:

  • Posted to your designated Slack channel for team review
  • Logged in Airtable for campaign tracking and reuse

⚙️ Setup Steps

Prerequisites

  • Active OpenAI API account with GPT-4 access
  • Slack workspace with admin permissions
  • Airtable account for content storage
  • n8n instance (cloud or self-hosted)

Configuration Steps

1. Credential Setup

  • OpenAI API Key: Required for GPT-4 content generation
  • Slack OAuth2: Needed for posting messages to channels
  • Airtable Personal Access Token: Essential for database operations

2. Form Configuration

  • Form fields are pre-configured for:
    • Product Name (text input)
    • Product Features (textarea for detailed descriptions)
  • Form can be embedded on websites or shared as standalone link

3. Slack Integration Setup

  • Connect your Slack workspace to n8n
  • Create or select target channel for ad copy notifications
  • Update the channelId parameter with your channel's ID

4. Airtable Database Preparation

  • Set up table with columns:
    • Product Name (Single line text)
    • Product Features (Long text)
    • Ad Copy (Long text)
    • CTAs (Long text)
  • Copy base and table IDs from Airtable URLs
  • Update workflow parameters accordingly

5. AI Prompt Customization
The default prompt generates versatile marketing copy, but you can customize for:

  • Industry-specific terminology
