Case Study Builder

Most case studies read like project reports — chronological, generic, forgettable. The Case Study Builder dramatizes the transformation instead, using a five-act structure that mirrors how prospects actually evaluate a buying decision.

What this skill does

Most case studies fail in the same way: they describe the process instead of dramatizing the transformation. The reader doesn't care what you did — they care whether you can solve their problem. Every sentence has to help the reader see themselves in the story. The Case Study Builder enforces the SCSR-T framework: Situation, Challenge, Solution, Results, Testimonial, in that order, because that order mirrors how a prospect actually evaluates whether to hire you.

The Solution section is where most case studies go wrong, so the skill is opinionated here. It's insight-led, not process-led. "The audit revealed something surprising..." reads as expertise. "First we did an audit, then we analysed the data, then we redesigned..." reads as a paint-by-numbers timeline. The Solution is also kept deliberately shorter than the Challenge plus Results combined — because prospects care more about the problem and the outcome than the middle.

It won't fabricate. If you don't have the baseline, it writes "Achieved [result]" and inserts [NEED: starting baseline for comparison] so you know exactly what to fill in. If you don't have a testimonial yet, it generates a client-friendly quote prompt engineered to elicit specific, quotable responses — not generic "they were great to work with" sentences. If you ask it to inflate the results, it refuses cleanly and reframes modest numbers with context instead: "A 5% revenue increase on a $2M base is $100K annually." Let the math do the work.

Output comes in the length that matches the use case — 800 words for web, 1200 for downloadable PDF, 300-400 for proposal inserts, 100-150 for portfolio thumbnails. There's an anonymisation mode that strips the client name while keeping the self-identification triggers (industry, size, role) and all the metrics — because numbers stay credible even without a brand attached.

When this triggers

  • ·You just closed a great client outcome and want to write it up before the details fade
  • ·You have a result but no testimonial — you need a quote prompt your client will actually answer
  • ·You're anonymising a confidential project and need it to still convert
  • ·You need the same case study in three lengths (web, PDF, proposal insert)
  • ·Your existing case studies read like timelines and nobody reads past paragraph two

Example

Trigger

User: 'Write up the project where we got Acme from $45K MRR to $128K MRR in 90 days. Confidential client.'

Output

Headline number (callout): $45K → $128K MRR in 90 days THE SITUATION A 30-person B2B marketing agency, 4 years old, founder still closing every deal personally. Recurring revenue stalled. THE CHALLENGE Surface problem: "we need more leads." Underlying problem: the pricing page wasn't the issue — every lead saw the same three-tier package and self-selected the cheapest. Stakes: losing 3-4 qualified prospects per week to competitors. THE SOLUTION (insight-led, not process-led) The audit revealed 73% of visitors left on the pricing page. Not because prices were wrong — because the page didn't answer the one question every buyer has: "what exactly am I getting?" THE RESULTS — primary, plus 3 supporting metrics, plus timeline. TESTIMONIAL — quote prompt provided since the user has none yet: "Hi [name], I'm putting together a brief case study about our work on [project]. Could you share 2-3 sentences about..." [NEED: starting baseline for lead-quality metric]
