Hi. You can talk to me the way you'd talk to anyone. Interrupt me, change your mind, think out loud. I'll keep up.

The cast

A voice for every moment.

Calm for a recap, bright for a brainstorm, measured for the hard questions. Press play on any of them.

George

Measured British

Think of a black hole less as a hole, and more as a place where the way out simply stops existing. Every direction still exists. They just all point inward.

Bella

Bright and energetic

Wait — what if the app didn't ask for anything at first? Let people use it for a day, then ask. That changes the whole onboarding.

Michael

Steady and precise

The strongest argument against it is cost. Not the price itself, but what you give up to pay it. Let's look at that first.

Easy-going British

You've got eggs, half a lemon and some spinach. That's a very good omelette. Ten minutes, one pan.

Modes

Shape how it sounds.

  1. 01

    Text to speech

    Paste a script, a note or a whole article. Pick an engine and a voice, hear it in seconds and download it as an MP3.

  2. 02

    Direct the delivery

    Describe the performance in plain words — calm, excited, a whisper, a sports announcer — and engines that take direction follow it. Or cast the voice that already fits the brief.

    The brief
    “Calm, warm and unhurried, like a thoughtful colleague recapping a meeting.”

    Here's what you agreed. Maya owns the launch plan, the budget review moves to Friday, and you'll send the deck tonight.

    Set the pace

    Slow it down for learning or speed it up for a quick listen — from 0.75× to 1.5×.

    Good morning. Your first meeting moved to ten thirty, so you have a clear hour. I'd start on the proposal while it's quiet.

    A preview of the range — in Voice Studio the speed is rendered into the voice itself.

Five voices

Same words. Five different voices.

One line of script, read by five AI voices. Hear how much the voice changes the message — then pick yours.

The line
I read your draft twice. The idea is strong — but the opening hides it. Lead with the moment everything changed.

Talk it through.

Some ideas take shape faster out loud. Say what's on your mind and hear the answer spoken back.

Both sides of this exchange are AI voices.

    I'm giving a talk on Thursday, and the opening feels flat.

  2. UltraGPTHeart · Open model

    Then open with the moment you changed your mind. Tell them what you believed before — and what made you stop.

    Like the launch that didn't work?

    Exactly that. Keep it under a minute. The numbers will land much harder after a story.

Some things are easier to say than to type. So say it the way it comes — and we'll find the shape of it together.
