I made a web app to practice English at advanced levels by having 2-way voice conversations with AI. But topics are taken from your Twitter followings section.
Why I made this app? It's not hard to read documentations, or listen a podcast. But how about convince native speaker to change his mind in a discussion? Or jump into a group conversation and tell a story? This last mile of learning language is a pain. And it's my personal problem.
Why Twitter? Twitter feed is a source of hot advanced topics in short form. And it is already customized to your specific interests.
Such conversations give much more fun and benefits than discussing again and again boring general topics like "sports" or "movies". So the time spent on practice not feel wasted.
