macOS companion app$4 / monthYour own style

Improve selected text anywhere on macOS.

McWritely captures the text you select, rewrites it with your saved style prompt, and drops the result back into the app you were already using.

How it works

1. Select text

Highlight anything in Slack, Mail, browsers, or editors.

2. Trigger McWritely

Use the global shortcut and McWritely captures the current selection.

3. Apply the rewrite

The backend rewrites with your saved style, and the app pastes it back in place.

Style customization

Onboarding collects one default prompt per account so rewrites follow your preferred tone, brevity, and voice.

Privacy posture

Raw selected text is sent for rewriting, but the SaaS layer stores metadata and billing state, not full text by default.

FAQ

Do I need my own OpenAI key?

No. The companion app authenticates to McWritely and the backend calls OpenAI.

Can I set my own writing style?

Yes. Each account stores one default style prompt collected during onboarding and editable later.

Are downloads private?

Artifact URLs are public, but rewrites only work for linked, entitled accounts.
