Marketing trend and seasonality analysis
Separate baseline trend, seasonality, and unusual weeks before attributing a performance change to advertising.
Keep the mappings, filters and model options in your project.
One daily or weekly panel CSV powers cannibalization diagnosis → contribution breakdown (MMM) → regression/forecast. Daily data is normalized to weeks automatically, and you can switch among the five mapped targets at any time. CSV data is processed in your browser and never sent to a server. Manage device storage and deletion in Storage.
