rewr.it for Mac

Your voice, wherever you write.

Select text in any Mac application, press a key, and get it back sounding like you rather than like a language model. It works in Mail, in Slack, in a document, in a text field on a website — the app comes to the writing instead of the writing going to a browser tab.

How it works

  1. Select the text you want to fix

    Anywhere: a half-written email, a paragraph a chatbot gave you, a Slack message that reads as stiff.

  2. Press ⌥⌘R

    A small panel appears with your selection already in it. You can also right-click and choose Services → Rewrite with rewr.it in applications that offer it — that route needs no permissions at all.

  3. Choose what you want changed

    Sounds like me is the default. Shorter, warmer, more direct, less formal, and clearer are one click each. Or hand it three bullet points and let it write the prose.

  4. Read it, then decide

    The rewrite arrives with a note about what changed and whether the facts, names, numbers, and links survived. Nothing is replaced until you press Replace — and Copy and Undo stay available afterwards.

What it reads, and what it keeps

It reads the text you select when you invoke it, and nothing else. It is never watching a field, a document, or an application.

Your drafts are not kept. There is no history of what you selected or what came back. The app borrows the clipboard for a moment to take the selection and hand the rewrite back — a clipboard manager can see that moment, and nothing else can.

macOS asks for Accessibility permission the first time you use the shortcut, because reading a selection that way means synthesising a copy keystroke. That is the only thing the permission is used for, and the Services route never needs it.

Before you install

RequiresmacOS 12 or later, on Apple silicon. There is no Intel build yet.
SignedNotarised by Apple, so it opens without a warning. It is not on the Mac App Store — sandboxed apps cannot read a selection from another application, which is the whole point of this one.
AccountOptional. Without one, rewrites use the house voice and everything else works. Signing in is what lets it use the voice profile you built.
FormattingReplacing a selection replaces plain text. Bold, links, and list structure inside the selection are lost, so Copy is the safer move in a formatted document.
UpdatesIt checks once at launch and offers. It never restarts itself while you are working.
