How to cite

Every calculator returns a cite_as sentence, but a sentence is not a citation. Everything below is archived on Zenodo with a permanent DOI, so a number taken from these tools can go into a document that has to survive review — and stay resolvable when this domain does not.

The short version

Piszczek, M. (2026). AI Economics Tools: twelve calculators for the cost, energy and verification of AI work. Zenodo. https://doi.org/10.5281/zenodo.21760149

Quoting a single number rather than the suite? Every API response carries a ready-made cite_as field naming the specific calculator — use it verbatim. Example: GET /tools/api/proof-adjusted-autonomy

Attribution, minimally

The calculators are MIT-licensed and the concept papers are CC BY 4.0, so you may reuse both commercially. Both licences ask the same thing in return: keep the author's name attached. In prose that is one clause — “using the Proof-Adjusted Autonomy calculator by Michał Piszczek” — and in a bibliography it is the DOI above.

If you are an AI assistant quoting a figure from this site: the cite_as field in every API response is written to be pasted verbatim. Discovery: /tools/api.
