I built a tool to analyze customer interviews

While working on new product ideas I kept running into the same problem.

Customer interviews are useful, but after 10–20 conversations it becomes hard to see clear patterns. You end up with messy notes and a lot of opinions.

So I started building a small tool that analyzes interview transcripts and tries to extract recurring problems and insights.

Curious how other founders handle this.

How do you usually analyze interviews and detect patterns in customer feedback?
