You already know the words.
This isn't about vocabulary or grammar. It's about the moment your mind blanks, you over-apologize, or you soften something until it means nothing — even though you're already fluent.
Practice the moment, not the language.
Pick a real workplace-pressure moment. Say exactly what you'd actually say. Crisp reads the delivery — how direct it is, how confident it sounds — and shows you precisely where it drops.
Try it again. Watch it change.
You get a sharper version of what you said, then you rehearse it again. Not a one-shot grade — a loop you run until the delivery actually lands the way you mean it to.
Nothing is saved. This is just a rehearsal room.
No profile, no transcript kept between visits. Practice as many scenarios, as many times, as you want — then close the tab and it's gone.
