Best Case Study Builder Tools for Media Buyers (2026 Comparison)

Why Media Buyers Need Dedicated Case Study Tools

Gone are the days when a few screenshots and a Google Doc could serve as a professional case study. In 2026, clients expect verified data, polished presentations, and comprehensive campaign narratives. The right tool can transform hours of manual work into a streamlined, automated process.

We evaluated the leading case study and portfolio tools available to media buyers, comparing them across six key criteria: data integration, automation, customization, verification, pricing, and output quality.

The Evaluation Criteria

Each tool was assessed on:

Data Integration: Can it pull directly from ad platforms (Meta, Google, TikTok, Snapchat)?

Automation: How much manual work is required to create a case study?

Customization: Can you brand and tailor outputs to your audience?

Verification: Does it provide verified, tamper-proof metrics?

Pricing: Is it accessible for freelancers and small agencies?

Output Quality: How professional are the final deliverables?

Frequently Asked Questions

Do I really need a dedicated case study tool?

If you create more than 2-3 case studies per month, yes. Manual creation takes 3-5 hours per study. Automated tools reduce this to 15-30 minutes, freeing you to focus on campaign optimization.

Can I use these tools for agency client reporting too?

Most of these tools serve double duty. AdsLap's campaign auditing works for both internal optimization and client-facing reports. Databox is primarily designed for ongoing reporting.

What makes verified data important for case studies?

Verified data pulled directly from ad platform APIs cannot be manipulated, unlike screenshots. This builds trust with sophisticated clients who know that metrics can be fabricated. A verified badge signals professionalism.

How often should I update my case studies?

Review your portfolio quarterly. Remove outdated studies (older than 18 months) and add fresh ones reflecting current platform features and strategies. Keep 5-8 active studies covering diverse industries and platforms.
