How to Write a Case Study | AI Tools & Tips

The best way to demonstrate that something works is to show it in action. This is why case studies are such a powerful tool in marketing: they don’t just tell someone that an approach works—they offer definitive proof to potential customers and clients.

Of course, writing up a case study can be an involved process. Thankfully, QuillBot’s AI case study generator can help you quickly capture the key details of your case study, so you can focus on sharing your success story.

How to write a case study

Though no two case studies are alike, they generally follow a consistent structure.

1. Introduce the problem

Start by outlining the challenge you’re addressing. Make sure you’re specific enough that your audience can relate, but keep your explanation clear and concise.

Emphasize why this issue matters—for example, maybe it’s costing stakeholders time, money, or other valuable resources. Framing the stakes helps show why your solution is essential.

2. Outline the solution

Once you’ve established the need, you should detail your solution. Describe the product, service, or approach you’ve implemented.

Focus on how your solution directly addressed the problem you previously described and highlight any unique features or strategies that set it apart. You may be competing with other options—now is your chance to demonstrate why your approach is the best possible choice.

3. Showcase data that prove it works

Describing a solution is one thing; proving that it works is another. A case study shows your product or service in action.

Back up your story with data, metrics, or testimonials that irrefutably indicate its effectiveness. Whether it’s increased revenue, higher engagement, or improved efficiency, concrete evidence builds trust and credibility.

Case study prompt example
See how the introduction, problem, and solution are outlined in this prompt:

A local cat café was losing customers because the cats preferred napping in the back room instead of mingling with visitors. The café introduced a rotating “treat time” schedule that encouraged the cats to socialize with guests. Within a month, customer visits doubled and social media engagement tripled.
