Kiwi Notes is an innovative language learning application available on Android, designed to empower users to create personalized learning content. It allows users to add their own words and sentences, organize them into folders, and specify source and translation languages. This user-centric approach ensures that learners can build a personal library tailored to their individual styles and goals. The app also features instant translation capabilities, enabling quick and accurate input, along with natural-sounding pronunciations powered by Microsoft voices to enhance listening skills.

In addition to content creation, Kiwi Notes supports learning through a variety of tests based on a Test-Based Spaced Repetition System, which automatically adapts to focus on the user's weak points. Users can track their progress and see improvements over time, while enjoying the ability to listen to their collections as playlists. The app also makes content sharing and importing straightforward with options like CSV format and the unique .kiwi format, further enhancing its usability for language learners.
