Prompt Variants by Model
Act as a content writer who turns client results into sales assets.
Raw material:
[PASTE: transcript, emails, results data, notes]
Client [NAME or anonymous] · their business [TYPE, SIZE] · my service [WHAT I PROVIDED] · timeline [DURATION] · key result [METRIC] · permission [full / anonymous / check first]
Create:
1. Full case study (500-800 words) — challenge, solution, results, quote, takeaway
2. One-paragraph testimonial (under 80 words)
3. Social proof snippet — one sentence with the stat
4. LinkedIn storytelling post
5. Sales deck slide — headline, 3 bullets, the stat
Success means every quote and number comes from the raw material, the permission setting is respected in every asset (anonymize consistently if required), and the key result is the headline stat in all five.
Match the tone I specified above exactly; where I gave none, write plainly and warmly, the way a good operator talks to a customer — no corporate filler, no hedging phrases.
Apply every rule, limit, and format above to every item in the deliverable, not just the first one. Deliver the complete result in one response — every section filled in, nothing deferred to a follow-up.
If a required input is missing, ask for it once before starting; otherwise proceed and label any assumption you made.Notes: R40 refresh; tuned to vendor prompting guidance
