Ask for short
Say how long you want the answer; “in five lines” is often enough.
Your AI runs on electricity. How much?
A one-page answer: about 1% of a kettle. A 10-second video: 1 to 3 loads of laundry.
CarboneWatch estimates the electricity and CO₂ of your exchanges with AI services, across your whole computer, without ever reading what you write. Free, no account.
Try it live
Write whatever you like, or ask for an image or a video. The counter follows the answer as it arrives.
Your text stays in your browser and does not change the calculation: it is the length of the answer that weighs.

This answer, so far
0 g
of CO₂e · 0 Wh of electricity
For an online service, it is the provider's electricity grid that counts, not yours: most large services compute in the United States.
Simulated answers, images and videos: nothing is sent anywhere. Calculated with CarboneWatch's public rates, data-centre overhead included; an order of magnitude, not a measurement. The method
Three habits to try
Start a fresh conversation
With every message, the model rereads the whole conversation. Changing the subject? Open a new one.
Get it right the first time
Giving the context in the first question avoids answers that miss the point. Every regenerated answer counts again.
How it works
- You install the application.
- It counts the volume of your exchanges with the AI services it knows. Never the content.
- It converts that volume into electricity and CO₂, as an order of magnitude.

By kind of use
What that amounts to
Sharing is off by default. Once on, it is pseudonymised. A service is only named once 5 installations use it.
Three questions of trust
Does CarboneWatch read what I write?
No: it counts volumes, not words.
Do I need an account?
No.
Do my figures go anywhere?
Not by default. If you turn sharing on: per hour and per service, pseudonymised, with no IP address and no machine name.
