NO KEYBOARD REQUIRED
NO PROMPTS.
NO PERFORMANCE.
JUST TALK.
You don't need a clever opener. Just your voice — and maybe a glass of wine.
You“I can’t sleep.”
Ember“Good. Neither can I. Come closer and tell me why.”
Based on the live app screen.
Hear it for yourself →HOW IT WORKS

Whatever's on your mind. Or whatever's been on it all day.
HEAR IT BACK
A voice that answers in real time — and picks up right where you left off.

Same you. Different depths.
Close. Tender. Dangerously easy to talk to.

For when you'd rather not be in charge.

YOUR DESIRES STAY BETWEEN US.
Your words. Your memories. Your call.
Read our privacy →What you control →Invite-only.
No crowds. No strangers.
Every memory is yours.
Keep it or erase it.
Erase everything, anytime.
One setting. All of it.
Adults only.
