Sustainable AI

Tools for using AI
more intentionally

Four browser-based tools. No account. No data sent anywhere. Each one teaches a method while doing the job โ€” and connects to the others.

Model Router

Five task types, three factors, one recommendation. Find out which model tier your task actually needs โ€” and see exactly how much water and cost you save vs defaulting to the strongest model.

Eval Bench

Define what "good" means for an AI task, score two prompt versions against a rubric, and find out whether the delta is a real signal or just noise. Works offline with four built-in task types.

The idea behind the toolkit

Each tool teaches a method, not just a number. The conviction underneath all of it: once you can see what a thing costs, you can make it cheaper without sacrificing the quality that matters.

Offline firstNo data leaves your browser. Every score and recommendation is computed locally.
Honest uncertaintyEstimates carry a 5โ€“10ร— range. The relative comparisons matter more than absolute numbers.
ActionableEvery tool ends with something to do, not just something to know.
ConnectedEach tool links to the others โ€” they're designed to be used together.
