Ehsan's Recommendation

This is the poor man's data analyst — and it is surprisingly good. A product manager who exports PostHog funnel data to ChatGPT gets analysis that is 70% as good as a data analyst, in 5 minutes instead of 2 days. For companies without a dedicated data team, this combination is transformative.
