Rehearse the hard part of your next English call

Ember puts an AI speaking partner in your browser — practice one tough conference-call moment out loud, so you walk in already having said it once. We’re rebuilding it with a far more natural voice. Join the waitlist and we’ll email you the moment it opens.

Built to rehearse, not to chat.

Ember is for the 30 seconds that actually matter on a call — the interruption, the pushback, the close. Practice it out loud until it feels easy.

What early testers say

Ember is in private beta with non-native professionals. A few notes from the first weeks of rehearsing.

“

I always knew what I wanted to say — I just froze in English. Saying it once to Ray first means I actually say it on the real call.

Mina K.

Product Manager

“

Five minutes before a client call I run the “push back” rehearsal. I walk in calm instead of rehearsing it in my head.

Daniel R.

Software Engineer

“

It’s not another chatbot — it makes me actually talk. That’s the whole point, and it’s why it sticks.

Sofia A.

Product Designer

“

I used to over-prepare and still blank. Now I rehearse the exact line once and it’s just there when I need it.

Hiro T.

Operations Lead

“

My manager said I sound more direct in reviews now. I didn’t tell her I rehearse it with Ray first.
