A good script isn't the hard part.
You can know every word and still lose the moment when the other person pushes back, changes the question or waits for a decision. That's the part Luwy trains.
Most speaking practice stops at the answer.
Another chat turn or a corrected sentence helps a little. It misses what makes talking to people hard: their reaction changes what you have to do next.
The person you talk to has a goal.
A hiring manager wants to know why you. A manager wants to protect the deadline. A customer wants the refund. Each one has a role, a priority and a point where they lose patience. You don't set any of that up. You just start talking.
Then you see where it turned.
Luwy picks the one answer that changed the conversation and quotes it back to you. Not every sentence, just the one that mattered. The meters shown during a run are estimates for that scenario. They're a way to see cause and effect, not a reading of anyone's mind.
You rewind and try again.
Retrying is where the learning happens. You say the answer a different way and Luwy shows both takes side by side. The goal is a better choice, not a prettier sentence.
Then you prove it.
Prove it gives you a fresh situation with no hints and no model answer. If you handle it alone, the skill counts. If you don't, you know exactly what to practise next.
