AI Education · Learning Assistant
Best for: Developers and teams curious about a rough footprint of their AI use.
Pros
- Estimates energy (kWh), water and CO2 for AI calls to ChatGPT, Claude, Gemini, Perplexity, Mistral, DeepSeek and 20+ other providers
- Metadata-only: it logs provider, model and token counts, never prompt or completion text, and tracking runs locally unless you turn on cloud sync
- Free tier covers 3,000 tracked calls a month; Pro adds forecasting, budget alerts and ESG CSV/PDF exports
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.
Starting 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)
