How much energy does your AI use?

A rough, honest estimate — in about ten seconds. No account, no tracking, nothing leaves this page. Move the numbers and watch the range change.

Tell us roughly how you use AI

Start with the closest match, then fine-tune if you like.

Messages on a typical day 20 How many days a week? What do you mostly use it for? (affects message size)

Your estimated AI energy — per month

Low–medium confidence

Why is this a range, not one number?

△ We don't know exactly which model served each message

△ We don't know which data center, or how it's powered

△ Your messages vary in length from one day to the next

So we show an honest range instead of a made-up exact figure. That's the whole idea. See our full method →

💧 And roughly the water… roughest estimate

—

Data centers use water for cooling, and more is used generating the electricity. Nobody publishes which data center served your prompt — so this range is very wide. That's exactly why we never put water in your real footprint. Why →

This is a guess. Want the real thing?

The Carbon Canvas extension measures your actual AI usage automatically — privately, in your browser, without ever reading your conversations.

These are rough scenario estimates for curiosity and learning, not a formal carbon audit. Energy is our most confident figure; the water range is far rougher and shown only for perspective. Both are built from the same published research behind our methodology (e-0.2.0), expressed as ranges because the exact infrastructure serving any AI request isn't public. We don't show a carbon number here — that needs location data we won't guess at.
