Team members ask questions in the tools they already use and get answers with numbers, charts, and sources.
Dot breaks down why a metric changed, attributing movement to contributing channels, segments, or factors.
Schedule reports and threshold-based alerts that trigger only when a metric crosses a level you care about.
Train Dot with instructions, examples, and business rules so metrics follow your organization's definitions.
