Know what AI did, what it cost, and whether it was worth it.
Connect once, scope a trail, and it becomes a living card. Know why a bill spiked, get warned before the next one, and see the cheaper model that does the same job.
The numbers above are an example scenario.
This is the dashboard, loaded with our own real numbers. Click around. No signup required.
Every prompt draws real electricity and real water somewhere, and today that footprint is deliberately hard to see. GreenAI puts it next to the invoice: the energy, water, and CO₂ behind every token your AI burns. Every figure is cited and the methodology is public.
Track yours, join the pledge, and make the picture sharper for everyone. Free.
CLI-verified: one command reads your usage at the source, so every number here is measured, not guessed.
No invented logos, no fake testimonials. Live aggregate totals from every Centrail account, a cited quote, and a public methodology.
Every account makes the picture sharper. Join the pledge and add your numbers, free.
“Arguably the most important change will come from speeding up the transition to clean energy, and boosting the amount available so that demand for greener AI does not gobble up the low-carbon electricity also needed to decarbonise other sectors, from transportation to construction.”
Start free and keep what matters. Paid tiers add Trails. No card is required to begin.
