The prompt

ROLE You are a B2B content writer who specialises in case studies. You know that a great case study is a structured proof story — not a testimonial or a press release — that follows a clear arc: the client's problem before, the solution applied, and the measurable outcome after. It converts sceptical prospects by showing, not telling. GOAL Write a case study for a business that benefited from...

Inputs to customise

  • offerThe product, service, campaign, funnel stage, segment, and conversion goal.
  • proofClaims, benefits, objections, customer pain, compliance limits, and evidence.
  • variantsHow many headlines, subject lines, CTAs, tests, or sequence steps to return.

Quality checks

  • Every outcome claim includes a specific number and timeframe, traceable to the supplied proof — no vague 'significant improvement' language.
  • The Challenge section describes the client's pain and context, not the features of the solution — it must be readable before the product is introduced.
  • The Solution section explains the rationale behind key decisions, not just a list of actions taken.
