Instreamia makes learning a language fun - learn by watching videos, listening to music, reading articles, and interacting with others. With Instreamia, you can expand your world in exactly the ways that interest you. It is built on the world's leading technologies in computational linguistics, allowing its to interpret many forms of online media and make them into viable learning vehicles. We've found that learning languages (as with learning in general) is all about making connections. So, Instreamia uses technology to make those connections--millions of them--and passes them on to you. Then it records your actions--your responses to exercises and interactions with text--and adjusts your learning accordingly. Every student is different, so Instreamia is adaptive: it gives you content that interests you at your level, it progresses through the content you're leaning at the pace you set, and it incorporates new content just for you as you learn. »
