AI Carbon Tracker

AI Carbon Tracker shows you the energy and CO₂ emissions of every AI response — live, as tokens stream. Works across 9 major AI chat platforms including ChatGPT, Claude, and Gemini, as well as other popular services. Features: • Real-time token counting (input + output as they stream) • Full carbon accounting: compute + cooling + hardware amortisation • Tracks pasted images, PDFs, and code files • Session and daily totals in the floating widget • 7-day history with per-service breakdown in the popup • Retry and regenerate button tracking • 100% local — no data ever leaves your browser Energy estimates include PUE overhead, cooling, and hardware lifecycle amortisation. Results carry ±30% uncertainty — AI energy accounting is genuinely hard, but the order of magnitude is right.
