The story
An interactive platform designed to help Arabic speakers learn German through a modern and engaging learning experience. It combines interactive lessons, a clean responsive interface and an AI-powered learning experience that keeps students motivated and progressing.
Tech stack
The Challenge
Language learners quit without instant, in-context feedback. Building a tutor that could explain German grammar accurately — in Arabic — while scoring pronunciation in real time required a careful AI pipeline and low-latency audio handling.
The Solution
I designed a structured prompt system with retrieval of grammar rules, streaming responses, and a pronunciation scoring layer that runs client-side for instant feedback. Adaptive scheduling uses spaced-repetition combined with AI difficulty estimates.
