ChartSensei

ChartSensei is a web app (with optional mobile companion) that teaches practical data literacy by turning real-world charts, dashboards, and headlines into short interactive drills. Users paste a chart image or a link, and the app guides them through a structured critique: what’s being measured, what’s missing, what assumptions are baked in, and what conclusions are not supported. It includes a “spot the trick” library (truncated axes, dual scales, survivorship bias, cherry-picked time ranges) and quick micro-lessons that take 3–5 minutes. For teams, it offers lightweight assignments and a shared rubric so managers can see improvement without becoming statistics experts. This is not a full statistics course; it’s a practical skill builder for everyday decisions, presentations, and meetings where bad charts cause bad calls.
