AI User Engagement Segments classifies AI tool users by how often they engage. It complements the daily-volume views (PRs merged per day with AI Intensity badge, distinct AI users per week) by giving you a per-person engagement profile.
The four segments
Power users — active on more than 50% of days in the period.
Casual users — active on more than 10% of days.
Idle users — active on 10% of days or less.
New users — their first AI activity ever falls within this period.
"Active" means the user had at least one recorded interaction with an AI tool (Copilot, Claude Code, or Cursor) on that day.
Companion daily/weekly metrics
The same dashboard panel surfaces two supporting views:
Distinct AI users per week — count of unique users who used any AI tool at least once per calendar week. Useful for tracking breadth of adoption over time.
PRs merged per day — daily PR merge volume during the period. The badge on this metric shows the estimated AI tooling cost per PR merged: total cost in the period divided by PRs merged.
How to interpret it
Many Power users, few Casual — adoption is concentrated. The team has internal AI champions but the practice hasn't spread.
Many Casual or Idle users, few Power — adoption is shallow. Seats may be paid for but underused.
Lots of New users in a single period — onboarding has just kicked off; expect Casual and Power counts to climb in the next few periods.
Distinct weekly users plateauing — the natural ceiling for the current pool. Further growth requires onboarding more people.
What to do about it
Pair Power users with Idle or Casual users for knowledge transfer.
Audit Idle users with paid seats — reclaim seats or run targeted enablement.
When AI Tool Cost is rising but the count of Power users isn't, you may be paying for seats producing little value.
