VocAdapt is an innovative language learning application that harnesses artificial intelligence to tailor texts and YouTube videos to your individual skill level, ensuring you understand around 90% of the material. This method promotes the natural acquisition of language by providing context rather than relying on traditional translations. When users come across new vocabulary, VocAdapt offers definitions in the target language and adds these words to a customized vocabulary list. To strengthen retention, the platform cleverly incorporates these newly learned words into subsequent content adaptations, which boosts both exposure and memory. Accessible as a browser extension for Chromium-based browsers, VocAdapt allows users to modify any online text or YouTube video according to their proficiency. The service includes a free plan that permits up to 15 text adaptations and 30 definitions each day while allowing unlimited vocabulary storage and access to a library of pre-adapted YouTube videos. Additionally, VocAdapt's user-friendly interface makes it easy for learners of all levels to engage with diverse content.
