Claude Prompts for Customer Research
By Joy Zhang · ex-Deloitte consultant running a one-person business with Claude
The best market research is already written — in reviews, comments, and forum posts where your buyers complain in their own words. Most founders never harvest it because reading 300 comments takes a day. Claude does it in one pass, if the prompt demands verbatim quotes instead of summaries.
A research prompt that says "summarize what customers think" produces mush. One that says "extract exact pain phrases, failed solutions, and objection language, verbatim only, and flag thin categories instead of padding" produces headline material and product direction you can act on the same afternoon.

Frequently asked questions
Can Claude do customer research without survey tools?
Yes. Its strength is qualitative analysis of text you paste: reviews, comments, support emails, interview transcripts. The structure of the prompt decides whether you get vague themes or verbatim, usable language.
What is the fastest research win for a new product?
Paste 2-4 star reviews of whatever your customers currently use. Mid-range reviews contain "satisfied-but" gaps — things people like BUT wish were different. Each gap is a positioning opening.
How is this better than asking ChatGPT about my market?
Asking any model to describe your market from memory produces plausible-sounding guesses. Feeding it real customer text produces evidence. The prompts here are built for the second mode.
