Ask HN: How do you understand what users want when your interface is a chat?

Building a conversational AI product and struggling with a specific problem: traditional analytics (clicks, funnels, heatmaps) are useless when there's no UI to track.

Curious how other founders handle this, how do you know what your users are actually trying to do? What intents are coming up most? Where are they getting frustrated?

Are you reading conversations manually? Building something internal? Just flying blind?
