Arabic Language
Infrastructure.
The most comprehensive Arabic language intelligence API — 477,000 lemmas, morphological analysis, Quran module, and AI tools for developers who build Arabic-first.
About
Arabic has 400M speakers.
It deserves better tooling.
KalimaLab is the API layer the Arabic language ecosystem has been missing. Built Arabic-first — not translated from English — every endpoint is designed around Arabic morphology: roots (جذور), patterns (أوزان), and classical grammar.
Whether you're building a word game, an NLP pipeline, an educational app, or a content moderation system — KalimaLab gives you the linguistic data you need on day one.
“Arabic is one of the most morphologically complex languages in the world. Building with it shouldn't require a PhD in linguistics.”
— KalimaLab
