Hussein Khalil

I’m the founder and developer of Kiwi Notes, an audio-powered vocabulary learning app designed for learners who want full control over their study material.

I focus on building calm, simple, privacy-respecting learning tools under the CopiaViva initiative — combining clear design, natural AI audio, and smart quizzes that adapt to each learner.
