What Yuki does

An assistant that works your Mac the way you do

And tells you what it's doing, every step.

⌘⇧A command bar

One shortcut, plain words

Press ⌘⇧A anywhere and a Raycast-style command bar appears. Type what you want — "email Bob about tomorrow" — and the bar gets out of the way the moment the task starts.

Activity pill

Watch every step, stop anytime

A small activity pill narrates the task in plain words — "Opening Spotify", "Typing…" — with a live progress bar and a STOP button. Touch the mouse or keyboard and Yuki pauses instantly.

Mid-task questions

It asks before it guesses

When a task is ambiguous, Yuki asks you mid-task right on the pill — tap an option button or type a quick reply — then carries on exactly where it left off.

Native app control

Real control of real apps

Direct control of Spotify, Apple Music, your browser, Mail, Messages, Notes, Calendar, and Reminders — plus any app via the accessibility tree. Element-level clicks, no screenshots.

Local memory

It learns you, locally

Yuki quietly observes your apps, music, and rhythm on-device, then distills daily notes into ~/YukiVault — plain markdown you can read and edit. Tasks use that memory of your people, projects, and routines.

Privacy first

Your data stays on the Mac

Raw activity never leaves your machine. Only small aggregated summaries reach the AI provider, and you can switch observation off entirely with YUKI_OBSERVER=0.

How it works

From a sentence to a finished task

1

Press ⌘⇧A and ask

A command bar drops down wherever you are. Tell it what you want in plain words — no syntax, no setup — and it gets to work.

2

Watch the pill, stay in control

The activity pill narrates each step with a live progress bar. Hit STOP anytime, answer its questions mid-task, or just touch the mouse — Yuki pauses instantly.

3

It gets more yours over time

Yuki learns your apps, music, and routines locally, keeping editable notes in ~/YukiVault. The more you use it, the less you have to explain.

Pricing
