WhyLensAutomatic insights that explain
what changed and why
Drop WhyLens on any Tableau dashboard. It reads the worksheets you choose and builds a full, interactive insights dashboard: trends, drivers, profitability, customers, forecasts and unusual periods, written in plain language.
An analyst's first pass, in seconds
No setup, no calculated fields, no templates. WhyLens works out what your fields mean (money, counts, rates, dates, regions, customers, products) and picks the analysis that fits.
Why it changed
Drills the change down to the segments that caused it, and splits it into volume, mix, price and margin effects.
Trends and seasonality
Year-over-year, seasonal patterns, weekday rhythm and period comparisons, with seasonality kept separate from real surprises.
Profitability
Where margin is made and lost: loss makers, discount break-even and margin mix.
Customers and products
Who is growing, who is new and who has gone quiet; Pareto concentration and top movers.
Outlook and anomalies
A seasonal forecast with a confidence band, and the periods that broke the usual pattern.
Click anything for detail
Every chart opens a detail panel: what drove that point, the biggest records, and a one-click filter.
PDF and PowerPoint
Export one page or the full report for your management meeting, ready to present.
English and Arabic
Full right-to-left Arabic interface and findings, with Arabic or Latin digits.
You stay in control
Choose sheets, measures, names and colours, and change the fields behind any chart.
