Only your voice.

A Mac app that lets you, and nobody around you, talk to your AI agents.

Download for Mac Apple silicon, macOS 14 or later. Free, MIT.
The yuzuzuzu window on Tasks: things to do taken from what its owner said, with times, reminders and two tasks marked kept on this Mac.
It opens on what there is to do, taken from what you said. Not on what you said.

It hears who is speaking before it hears what is said.

  1. Who

    Every phrase is checked against your voice on your Mac. Colleagues, a call, the TV: dropped before a single word is transcribed.

  2. What

    Only your phrases are turned into text, also on your Mac. Audio never leaves it.

  3. For whom

    The text of your phrase is weighed and cleaned: noise is dropped, numbers become tags. Then it goes to your agents' inbox and your tasks.

What might be sensitive does not leave the Mac.

Money, health, codes, addresses and names are found on your Mac, before anything is sent. They go only through Nebius Zero Data Retention, and while there is none, nowhere.

The Journal: phrases sent to the agents through the standard channel, and two phrases kept on this Mac because they mention money and a name.
The Journal shows what was sent, and what was kept and why.

Nothing to set up.

No enrollmentJust talk. It finds your voice among the voices it hears in the first minute and keeps learning.
Your agents read itClaude Code, Cursor and any MCP client get a clean inbox. Agents that read files get a Markdown file.
It remembers your promises"I'll send it tomorrow" becomes a task, and a reminder if you want one.
Your Mac's own sound is subtractedA video or a call playing through the speakers is not you, so it is not heard.
A microphone that hears only youPick "yuzuzuzu Microphone" in Grok, Claude, ChatGPT or Zoom. They hear you a second late, and not the room.
No wake wordYour voice is the key. A command from someone else in the room is just noise.

Install

Run in Terminal, or ask your agent to. It puts yuzuzuzu in Applications and opens it:

curl -fsSL https://yuzuzuzu.pages.dev/install.sh | bash

Or open the .dmg and drag yuzuzuzu to Applications. The build is not notarized, so macOS refuses that first launch: click Done, then open System Settings, Privacy & Security and click Open Anyway.

Then connect an agent:

{"mcpServers": {"yuzuzuzu": {"command": "/Applications/yuzuzuzu.app/Contents/MacOS/yuzuzuzu-mcp"}}}

For voice modes and calls, install the virtual microphone once (it asks for your password):

sudo cp -R /Applications/yuzuzuzu.app/Contents/Resources/yuzuzuzuMic.driver /Library/Audio/Plug-Ins/HAL/ && sudo killall coreaudiod
