AI-Powered Case Study Generation Workflow for Marketing Agency

A Marketing & Design Agency faced growing demand for client case studies as part of their content marketing services. While case studies were high-value assets for their clients, the process of gathering data, drafting, editing, and finalizing these documents manually took up to 3 business days per case study.

To improve efficiency and scale their output, they partnered with Contra to build a custom AI-Powered Case Study Generation Workflow using N8N, integrated with Openrouter, Azure AI Services, GPT, and Google Gemini.

The Challenge

Manual Effort: Writers and strategists had to interview clients, draft documents, revise multiple times, and format the final version.

Slow Turnaround: Each case study required nearly 3 full days of effort, limiting how many they could deliver per month.

Inconsistent Results: Manual drafts varied in quality and tone, requiring heavy editing.

The Solution: AI-Driven Case Study Workflow

Contra designed an automated workflow using N8N that connected various AI services to streamline the entire content production pipeline. Key features included:

Automated Data Gathering: Intake forms and structured client inputs were parsed and validated through Azure’s NLP models.

AI Draft Generation: GPT and Gemini generated first drafts based on provided context, using prompts optimized for tone and clarity.

Content Refinement Loop: The workflow auto-generated two to three variations, allowing the client to select the best fit.

Formatting & Delivery: The final draft was automatically formatted into the client's preferred template and sent via email or project management tools.

The Results

Time Savings: Reduced case study production time from 3 days to less than 6 hours, a 83% improvement in turnaround time.

Increased Capacity: Enabled the agency to deliver 6x more case studies in the same timeframe, helping them serve more clients simultaneously.

Improved Consistency: AI-driven outputs maintained a consistent tone and style, reducing the need for manual revisions.

Higher Revenue Potential: With increased output, the agency positioned itself to upsell content packages and expand client retainers.

By automating their case study generation process using AI-powered N8N workflows, this Marketing & Design Agency not only saved significant operational time but also unlocked new revenue opportunities by scaling their content production capabilities.
