If you write in Scrivener on a Mac and you’ve seen a little “Writing Tools” menu offering to rewrite your paragraph, you’re not imagining it. But it isn’t Scrivener.

Scrivener itself

Literature & Latte, who make Scrivener, say Scrivener contains no artificial intelligence and doesn’t send your text off your computer. Their blog post on the subject explains where the prompts come from. Their stated position is that whether to use AI tools is up to each writer, and they haven’t built any into the app.

Where the AI prompts come from

On a Mac running macOS 15 or later, Apple Intelligence adds Writing Tools to almost every text field in every app, including Scrivener, Word, Pages and your browser. Select some text and it’ll offer to proofread, rewrite or summarise it. That’s macOS, not the app you’re typing in.

If you don’t want it:

  1. Open System Settings.
  2. Go to Apple Intelligence & Siri.
  3. Turn Apple Intelligence off.

Windows has its own version of this with Copilot, which you can turn off in Windows settings, and some keyboards and browser extensions (Grammarly, for one) add their own.

Where the other apps stand

AppAI in it?
ScrivenerNo. macOS may add Apple’s Writing Tools on top.
Microsoft WordYes, Copilot is built in for many Microsoft 365 plans.
Google DocsYes, Gemini is built in for many Google Workspace plans.
UlyssesNo.
NovlrNo, and they’ve said publicly they won’t add generative AI.
The Novel FactoryNo. Its site says it’s AI-free and always will be.
NoveliumIt doesn’t write prose, but it does use AI to read your manuscript and check consistency.
SudowriteYes, it’s an AI writing tool. That’s the product.
GalleyNo.

These change. AI features get added to apps all the time, so check the current terms of anything you use, especially the part about whether your text is used for training. There’s a longer post on whether your writing is being used to train AI, with how to check.

Does it matter?

That’s your call. Plenty of writers use AI tools and plenty won’t touch them. What matters is knowing which is which, so that a tool doesn’t start rewriting your sentences or reading your manuscript without you deciding it should.

How Galley does it

Nothing in Galley writes, rewrites, suggests or finishes a sentence, and your book isn’t used to train any AI model, mine included. The tools that count overused words, check name spellings and typeset the page are ordinary code that gives the same answer every time. Your spellcheck is your browser’s own dictionary, so your words don’t leave your machine to be checked.

Galley can’t stop your operating system from adding its own tools to the page, the same as Scrivener can’t, so the steps above apply to Galley too. The no-AI post has the reasoning, and the Sudowrite comparison is the honest version of the other side.
