Frequently asked questions
Is the case study generator really free?
Yes. You can generate case study drafts from your own customer feedback with no account and no credit card. Saving drafts and the full multi-source builder unlock with a free account.
How do I turn a testimonial into a case study?
Treat the testimonial as the result, then build the story around it. Use the testimonial to identify the outcome the customer described, follow up briefly to capture the situation before and confirm any numbers, then structure the narrative as problem-solution-result using the customer's real words. Paste the testimonial into CustomerProof and the generator drafts a structured case study traced to the source quote — nothing is invented.
What does "source-verified, never invented" mean?
Every line in the generated draft is assembled from your own pasted feedback. The generator does not write new facts — it arranges your customer's actual words and shows you a source receipt for each claim, marking which excerpts trace word-for-word back to your input.
What can I paste in?
Any text-based customer feedback: product reviews, NPS or survey responses, support transcripts, interview notes, or direct testimonials. The richer and more specific the feedback, the stronger the traced draft.
How is this different from asking ChatGPT to write a case study?
A general AI tool will happily invent plausible-sounding metrics and quotes. CustomerProof only arranges claims it can trace back to your real source text, and shows you the receipt for each one — so what you publish is defensible.
