Chartcastr supports 13 pre-built PostHog metrics across four categories. Each metric is delivered with an AI-generated summary tailored to product analytics.

​
Active Users

DAU / WAU / MAU is the recommended starting metric — it gives a complete engagement picture in a single chart and pairs well with a daily or weekly Slack delivery.

​
Growth Accounting

The Growth Accounting chart is especially useful for product teams to understand whether growth is driven by acquisition (new), retention, or reactivation (resurrected) — and how much is lost to churn (dormant).

​
Events

​
Pageviews

​
Custom

v1 of the Custom Events Overlay uses a single shared Y axis. v2 will let you assign each event to a left or right axis so high-volume and low-volume events can share a chart cleanly.

​
AI-Powered Summaries

Every PostHog chart is delivered with an AI-generated summary specific to the product metric:
  • Active Users: engagement trends, DAU/MAU ratio (stickiness), weekly patterns
  • Growth Accounting: net growth signals, retention health, churn acceleration
  • Events: usage volume trends, anomaly detection, correlation with releases
  • Pageviews: traffic patterns, bot detection signals, feature adoption proxy
