Generates numeronyms from words and phrases. A numeronym is a number-based word (like i18n for internationalization, k8s for Kubernetes, a11y for accessibility) where the number represents the count of letters between the first and last character.
Numeronyms are a universal convention in tech (i18n, l10n, a11y, k8s) but manually counting middle characters is error-prone. This tool generates correct numeronyms instantly and shows you the breakdown.
