What it does
Plain-language answers from your data: what is typical, what is odd, what is moving and what is likely just noise. You paste a table or describe a metric, and get a written read of it, not a wall of numbers. It picks the right centre for the shape of your data, mean for even data and median for skewed, and often reports both so the gap shows skew. It adds spread, key percentiles and a note on outliers. For trends it uses moving averages and checks for seasonality. For comparisons it runs suitable tests and says when a result is too weak to trust. It also warns about weak claims, like treating correlation as cause.
