A writing assistant for macOS

The writing assistant
that sounds like you.

New Message ⇧⌘K · Rewrite in your voice

Demo: Keel rewriting a sentence in your voice, inside any Mac app.

Works where you write

One assistant. Every text field.

Keel lives in your menu bar. Select text in any app, press ⇧⌘K, and it rewrites in your voice — in English or Portuguese.

01 / Rewrite

A rewrite you can recognise as yours.

Select text in any Mac app. Keel keeps the meaning, removes the hedging, and leaves the final choice with you.

Quiet help while you type

02 / Correct

Catches the small things without interrupting the big idea.

Spelling, grammar, punctuation, and clarity are checked on-device. The correction appears where you are, then gets out of the way.

03 / Learn

Your voice is not a preset.

Keel learns from examples you choose: your warmth, rhythm, directness, and the habits you never want an assistant to smooth away.

Private by design

Your writing stays yours.

Everyday checks run on your Mac — your sentences never leave it. Stay fully on-device, or allow a cloud rewrite only when you ask for one. And your Voice Card is yours: see it, edit it, or clear it whenever you like.
