You can study Greek for months and still freeze when it's time to talk. Parlita fixes that by making you speak from the first session: real conversations with an AI partner, living stories you act inside, and the words you stumble on woven into spaced repetition so they stick.
What learning Greek is actually like
You know more Greek than you think you do. English pulled a few thousand roots out of it, so once you can read the alphabet, and that takes a couple of days, you start spotting words you already understand sitting inside sentences you do not.
The alphabet really is the quick bit. The verbs are the long project, because Greek has kept distinctions English dropped centuries ago and there are simply more forms to hold in your head than a Romance language asks for. Modern Greek is also not the Greek of the classics, so anything you did at school will help you with vocabulary and mislead you about almost everything else.
