ZeroTwo VoiceBeta

Just say it out loud.It answers.

A voice you can actually hold a conversation with — warm, quick, and able to look things up while you are still talking.

Human-like, not a phone tree

Warm, expressive, and quick on its feet — a voice that carries a real conversation and hears you out.

  • Speaks with real timing, tone, and warmth.
  • Start talking straight from the app — nothing to set up.
You are clear until two — want me to block an hour for the deck?
Sure, let me check Umesh's calendar real quick.
That report you asked about landed overnight. Do you want the short version, or the whole thing?

Trained for the real world

Real conversation is messy. ZeroTwo handles being cut off, the half-remembered detail, and the “actually, one more thing.”

  • Stays with a request until it is genuinely settled.
  • Looks things up and gets on with them while you are still talking.

Smart, without the wait

Most voice AI trades intelligence for speed. ZeroTwo doesn’t — real reasoning, with answers in under a second.

  • Trained on the hardest calls we could find.
  • Clear through background noise and strong accents, in 25+ languages.

Your tools, in reach

Ask out loud and ZeroTwo reaches the apps you already use, mid-sentence.

  • Gmail, Google Calendar, Outlook, Linear, Notion, OneDrive and the rest of the connectors.
  • Checks a calendar, drafts a reply, or files an issue without you touching a keyboard.
  • Add any MCP server of your own and it can reach that too.

Hands-free, anywhere

Walking, driving, cooking, between meetings — the conversation goes where you do, and picks up where you left it.

  • The same thread on the web, the desktop app, and your phone.
  • Switch to typing mid-conversation and back again.
  • Speak and be understood in 25+ languages.

Can you read me the card number on file?
I can’t read that back — let me verify your identity another way.
No PII read back

Cut in any time

Talk over it and it stops mid-word to listen. No wake word, no waiting for the beep.
