Playground

Every prompt you type into an AI burns energy, water, and carbon somewhere in a data center. Web Experts built Tokenprint (webexperts.com/tokens) to measure that: a free, cited calculator for the footprint of your AI usage. This is the playground edition. Say out loud whatever you would feed an AI, and it cuts your words into tokens the way a model sees them, then prints you a rough estimate of what those tokens cost the planet. The full cited numbers are on the real calculator; this version is the fast and loose one for coffee talk.

Rough playground estimates, order of magnitude only. Model inference averages about 0.002 kWh of energy per 1,000 tokens, roughly 0.75 grams of CO2 equivalent and about 2 milliliters of water on a typical US grid. Your mileage varies by model and location. Get the cited, precise numbers at webexperts.com/tokens.

The oldest joke in programming is the REPL: read, eval, print. Say something to a machine and it thinks and answers. This toy swaps the first step for something more natural. You talk, it cuts your words into tokens the way a model sees them, and prints them on a green terminal like it is 1982. The name comes from an old IBM machine that did the same trick with a secretary at the other end of a dictation belt. Listen, type, print. The loop is the point, and every loop needs a human at one end.

Runs entirely in your browser. Your words never leave the page, and the print button hands you a plain receipt of what you said, in tokens.
