Compare two time periods of Claude Code activity. Like a fitness tracker's "this week vs last week", but for your AI sessions.
Shows how your usage, AI autonomy, and Ghost Days changed over time.
npx cc-compare
npx cc-compare --period=month # this month vs last month
npx cc-compare --period=14d # last 14 days vs 14 days before that
npx cc-compare --json # raw JSON output cc-compare — week over week

Insights:
▸ You're more active this week
▸ AI autonomy increasing — your AI is handling more
▸ More Ghost Days — AI running more independently

- Your hours — time in interactive Claude Code sessions
- AI hours — time in autonomous/subagent sessions
- Autonomy ratio — AI hours ÷ your hours (>1.0 = AI working more than you)
- Ghost Days — days where AI worked but you had zero interactive sessions
- Active days — total days with any Claude Code activity
- Node.js 18+
