Best for: Developers and teams curious about a rough footprint of their AI use.
Biggest catch: The numbers are estimates converted from token counts using published research, not measurements, though the listing says 'measured in real time'.
Skip it if: You need audited emissions figures for formal ESG reporting.
Price: Free: 3,000 tracked calls/mo, 14-day retention. Pro $49/mo (5 seats, then $8/seat; 200,000 calls; +$10 per extra 100k). Enterprise custom. 14-day free trial, no card. (checked Oct 21, 2026)
