The right line for the moment ahead: a second date, their parents, a toast. With what it means, how it feels to natives, and a sound guide. 75 lines free.
Say the right thing in the moment that matters.
One Line gives you the exact line for the situation in front of you: a second date, a first dinner with their parents, a wedding toast, a chat at the coworking space, a reply you need to word well. Each line comes with what it means, how it feels to native speakers, and a sound guide that shows where to stress, what to link and what stays silent.
HOW IT WORKS
1. Listen: hear the line, then hear it slow and natural.
2. See why it lands: meaning, literal wording and how natives feel it.
3. Say it: check out loud that you got it, right on your device.
