About this site
AINumbers.co is a free, open-source suite of browser-based fintech tools. All tools run entirely client-side using deterministic, rule-based logic, so no data is ever transmitted to a server. Ideal for payments engineers, compliance professionals, treasury analysts, and fintech product managers who need to work with payment standards and financial regulations without standing up infrastructure.
