Testimonial to Case Study: One Prompt

Paste a raw testimonial or customer interview transcript and get the before/after story structured into a publishable case study with a pull quote.

Free prompt pack · copy-paste ready · built by the BrainVaultAI team

A testimonial is a data point. A case study is a sales tool. The difference is structure: situation, problem, solution, result, in that order, with specifics. Most founders have the raw material sitting in emails and Zoom recordings but never convert it. This prompt takes any raw customer input, a testimonial, a review, a transcript snippet, even bullet notes from a call, and returns a formatted case study ready for your site, a proposal, or a LinkedIn post. ### How to use

Paste the customer input into the [RAW INPUT] block. If you have specific metrics, include them. Claude will flag where numbers are missing and suggest placeholder language you can fill in later. The output includes a featured pull quote, a 3-paragraph narrative, and a results block. Run once per customer story. Takes 90 seconds.

[PASTE TESTIMONIAL, REVIEW, OR TRANSCRIPT NOTES HERE] My product/service: [ONE SENTENCE]
Customer's role/company type: [ROLE + COMPANY SIZE] Return:
1. Pull quote (1-2 sentences, most compelling thing they said, in their words)
2. Case study headline (outcome-first, under 12 words)
3. Three-paragraph narrative: - Paragraph 1: Their situation and the specific problem before working with me - Paragraph 2: What they did / how they used the solution - Paragraph 3: Specific results and what changed
4. Results block: 3 bullet points with metrics (use their exact numbers; flag as [PLACEHOLDER] where you're inferring)
5. One-sentence CTA to append to the case study Tone: factual, no superlatives, let the results speak. Third person.
Case Study Distribution Prompt: Repurpose Once, Use Everywhere
Paste this into Claude after your case study is drafted:

---
I have a finished case study. Repurpose it into 4 formats without adding anything that is not in the original.

1. LINKEDIN POST: 150-200 words. Start with the result, not the background. End with one question or observation.
2. EMAIL SNIPPET: 3-4 sentences. Written to drop into a sales email as social proof. No header, no context-setting, just the relevant outcome and a link placeholder.
3. SALES DECK SLIDE: Title + 3 bullet points. Each bullet is one concrete data point or outcome. No adjectives.
4. WEBSITE TESTIMONIAL BLOCK: 40-60 words. First-person voice as if the customer wrote it. One result, one specific detail, one sentiment.
