Here's what Enguy actually does differently
You are not here because your English is bad. you are here because talking out loud with someone listening is a different skill than reading or writing — and most tools that claim to help make that worse before they make it better: a score after every sentence, a tutor's calendar to work around.
Enguy skips both. It's a real-time voice partner. you talk, it talks back — no lag, no typing — and when you say something awkward, it folds a better way to say it into the reply, instead of stopping to grade you.
