“Sasarisa, play lofi on YouTube” — the video starts in Safari and the card in the corner confirms it
Why Sasarisa

Dictation apps turn speech into text. You still have to click, open, search and send — by hand.

Sasarisa finishes the job. Everyday things happen on your Mac in about a second; anything that needs thinking goes to Claude Code, which looks at the screen and does it. It gets faster the more you use it.

What it can do

From easy chores to coding,
just say it.

Green happens on your Mac in about a second. Purple goes to Claude Code.

Claude

Several at once and your own routines work too — and it's Korean-first, with 12 languages supported.

How to call it

Call it, or hold a key and talk.

Rename it if you like. After the first call, keep talking for 30 seconds without the name.

“Sasarisa”or “Hey Sasarisa”

Talk after the chime. It acts within 0.9 seconds of you finishing.

Right ⌥ hold & talk

Like Handy: listens while held, runs on release. Most accurate in noisy rooms.

“That's all” · “Stop”

Cut in any time — even over speakers, if you talk close to the mic.

Speed

No waiting for the everyday stuff.

Time from the end of your sentence to action (measured on a Mac mini).

What you say often moves to the instant side the more you use it.

Safety

A voice in a video must never drive your Mac. Anything irreversible waits for your yes, and your voice never leaves the Mac.

SasarisaPress “Send”?
YesNo
Send, pay, delete — it asks. Even in act-right-away mode, irreversible actions wait for a spoken yes.
On this Mac onlyWake word · transcription
nothing uploaded
Your voice stays on your Mac. Listening and transcription run locally; only the text you hand to Claude leaves the Mac.
In a call · pausedwhile Zoom, FaceTime or Handy uses the mic
It pauses during calls. Meeting audio never becomes a command — it stops listening and comes back when the call ends.

Built on Claude Code.
Voice coding, all the way.

Fix anything red on the setup screen

Allow the microphone, speech recognition and accessibility, and download the transcription model. When ◉ shows in the menu bar, say “Sasarisa”.

Windows comes later. The Mac comes first; a Windows version follows once wake-word listening and transcription there are as quick as on the Mac.
