I built a small tool that checks how close your data is to a normal distribution. You just upload a CSV column, and it computes the KL divergence between your data and a normal distribution with the same mean and standard deviation.

No installation, no login, just quick feedback: https://ismydatanormal.com

Built it mostly for fun – but I’ve already found myself testing sleep patterns, messaging habits, and even some sensor data. Would love your feedback!
