Background
Affixation is one of the most critical yet challenging aspects of Indonesian morphology, but conventional practice methods still rely on static exercises that cannot adapt to individual needs. MorfoBahasa addresses this gap by providing dynamic, AI-generated affix exercises tailored to each user's proficiency level. Designed specifically for learners of Indonesian as a Foreign Language (BIPA), every exercise integrates Indonesian cultural elements with references from Wikipedia.
