Writing · Nook

How it works

Grey text after your cursor. That's all you see.

You typeIn Mail, Slack, Notes, a browser, anywhere with a text field. Password fields are always skipped.

Nook reads the fieldThe text around your cursor, the app and the site, and if you allow it, what's on screen and your clipboard.

A model on your Mac writes onIn your language and style, with your own instructions for this app or website.

Tab, or keep typingTab takes the next word, ⇧ Tab takes it all. Type something else and it simply steps aside.

Made to disappear

Smart where it counts, invisible everywhere else.

On your own MacYour built‑in MLX model or any GGUF model through llama.cpp, accelerated by Metal. Nothing you type leaves your Mac.

Per app and per websiteFormal in Mail, short in Slack, Dutch on one site. Turn it off where you don't want it.

Learns how you writeYour words and the phrases you write again and again, learned locally and stored encrypted. Card numbers, keys and passwords are filtered out first.

Emoji, typos, other wordsType : for emoji, get a typo fixed inline, or pick another word by number.

Easy on your batteryPauses on battery by default, or runs lighter: only when you pause typing, shorter, or with a smaller model.

Also in your editor's chatIn the Claude Code or Copilot chat box of VS Code and Cursor, never in the code editor or the terminal.

Statistics show how many words you completed and the time you saved. Nook only counts; it never stores what you typed.

Flow dictation

Hold a key. Speak. Release, and it's typed.

Anywhere on your Mac. Nook listens, cleans up what you said, and pastes it right where your cursor is.

Offline, in your languagesOn‑device speech recognition across your languages at once, or Parakeet on the Neural Engine.

Your words, your wayA dictionary for names, replacements, and snippets that expand when you say them.

Hands‑free when you wantDouble‑tap the key to keep listening, Esc to cancel, ⌃⌘V to paste the last one again.

Listening…fn

Double tap

Tap ⌘ twice. Say what to write.

Tap the right ⌘ key twice and a small field asks what Nook should do. With your cursor in a text, Nook writes right there.

Write at your cursor"Write a cover letter", "translate this into English", or "make the second paragraph shorter", in Word or any other app. ⌘Z takes it back.

Fill in the formNook fills the empty fields with what it knows about you, then shows what it filled with Undo. Nothing is sent by itself.

Some fields stay yoursPassword, payment and identity fields always stay empty, and buttons that pay or delete are never offered.

Questions

Good to know.

Does what I type leave my Mac?

No. Autocomplete runs on a model on your Mac, and password fields and Secure Input are never read. Statistics are counts only, never your text.

Which apps does it work in?

Almost every app with a text field, including browsers and Electron apps. Terminals, code editors and password managers are off by default, and you can switch any app on or off in Settings › Autocomplete.

Will Tab still work normally?

Yes. Nook only takes Tab while a suggestion is on screen. With nothing showing, Tab belongs to the app, and you can leave Tab to an app entirely.

Can I try it before turning it on everywhere?

Yes. Settings › Autocomplete has a Playground where you can type and see the suggestion, how long it took, and the exact prompt the model read.

Does dictation need the internet?

No. It runs on‑device, or offline with Parakeet on the Neural Engine.
