Jolii is an AI-powered language learning app that turns your favorite shows and videos into personalized language lessons.
Key Features:
◆ Watch Your Way:
Explore Jolii’s video library, paste a YouTube link, or connect your own Netflix account to bring your shows right into Jolii, in split-screen or full-screen mode. Get recommendations based on what you enjoy watching.
◆ AI-Powered Personalization:
Jolii analyzes your chosen YouTube and Netflix content in real time, crafting custom exercises tailored to your language goals, vocabulary level, and learning style.
◆ Context-Based Learning:
Unlike traditional methods that isolate words, Jolii focuses on learning within the natural context of YouTube videos, Netflix shows and music. This immersive approach fosters deeper understanding and better retention of vocabulary and grammar.
◆ Speaking Practice Anytime:
Enhance your fluency and gain confidence in real conversations with Jolii's AI chatbot. Answer questions about the scene, step into a character's shoes (Roleplay), practice pronunciation by echoing native speakers (Shadowing), and get instant feedback on how you did. No pressure, no judgment — just practice.
◆ Improve Pronunciation with Music:
Analyze song lyrics with Jolii, breaking them down into individual words and phrases. Practice pronunciation with phonetic transcriptions and gain a deeper understanding of the nuances of the language through music.
