How do founders get insights from CSVs, analytics, and surveys using AI?
The short answer
Upload the CSV or export from your analytics tool, tell the AI what decision you are trying to make, and it will clean, chart, and summarize by writing real code behind the scenes. The same works for surveys: paste open-ended responses and ask for themes, sentiment, and representative quotes. Spot-check a sample of the output against the raw file before you act on it.
A quick orientation. The real value is below: resources worth your time, from people who've actually done it.
