Nook Home: a to-do list, CPU, memory and disk stats, and a focus timer, all inside the open notch.

One hover to open. A whole new way to use your Mac.

Free forever MIT licensed Made for your workflow

SMALL SPACE. BIG UPGRADE.

Less switching.
More doing.

The little things you do all day,
right where you need them.

Dictation

Think it. Say it. Done.

Hold ⌃⌥ and talk. Groq Whisper turns your voice into text; AI tidies it up. Keep your history. Retry a missed take.

Bring your own Groq API key.

Volume mixer

Your sound. Your balance.

Set each app’s volume, all the way to 200%. Pick your mic and speakers, then pin them as your defaults.

Nook’s volume mixer with output device selection and a volume slider.

System monitor

A pulse on your Mac.

CPU, memory, disk, battery, and network activity. See what’s working hard without opening another window.

System Monitor showing CPU, memory, disk, battery, network speed, and top processes.

Home

A little command center.

Your to-dos, system stats, and focus timer together. Get your bearings, pick a task, and get into it.

The Home tab with a to-do list, system stats, and 15-minute, 30-minute, and one-hour focus timers.

Teleprompter

Stay on script. Stay present.

Your words scroll right under the camera. Keep your eyes up through the next call, demo, or recording.

Nook’s teleprompter with a script, scroll speed, font size, and playback controls.

Timers & focus

Make time for one thing.

Start a quick timer or settle into a focus session. Keep the countdown close and your attention on the task.

Nook Timers showing a 25-minute countdown, quick duration presets, and a stopwatch tab.

Whole-Mac proxy

Paste your proxies. Connect in one tap. Check your public IP right in the notch.

A place for a thought

Jot it down in Notes before it’s gone. Your next idea is always a hover away.

Drop it. Grab it. Go.

Drag files onto the Shelf, switch apps, then drag them out where you need them.

RIGHT AT HOME ON YOUR MAC

Feels like it
belongs. Because
it does.

Hover and it opens. Move on and it slips away. Smooth spring animations make a small space feel surprisingly natural.

A little movement. Everything within reach.

The Timers tab, open at the top edge of the screen with a 25 minute countdown.

Same notch. A world of possibilities.

Swipe into place

Two fingers to change tabs. Drag to reorder them.

Your own shortcuts

Give each tab a hotkey. Jump straight to what you need.

Every screen is welcome

No notch? Nook adds one. External monitors included.

Make a little room

Pin it open. Set a different height for every tab.

BUILT TO BE BUILT ON

Every tab
is a plugin.
Even yours.

An HTML/JS folder and a plugin.json. That’s a Nook plugin. Save a change and it’s live. No rebuild. No waiting.

Make your first plugin

HTML + JSHot reloadYour ideas

plugin.json

{
  "id": "my-widget",
  "name": "CPU",
  "symbol": "cpu",
  "entry": "index.html",

}

// Loaded by index.html, alongside a <main>.
const view = document.querySelector("main");

async function refresh() {
  try {
    const { cpu } = await window.nook.system();
    view.textContent =
      `${Math.round(cpu.usage * 100)}% CPU`;
  } catch {
    view.textContent = "CPU unavailable";
  }
}
refresh();
setInterval(refresh, 2000);

Edit. Save. There it is.

Small plugin. Real power.

window.nook connects your code to shell commands, fetch, storage, system stats, and notifications.

Settings, already handled.

Declare options in plugin.json. Nook builds the settings form and saves your preferences.

Useful, even when closed.

Show live activity on the closed notch. A build status, a countdown, or whatever matters to you.

AN IDEA IS ALL YOU NEED

Your next plugin
starts with a sentence.

Nook installs a nook CLI and an agent skill for Claude Code & Codex. Your agent gets the tools and the know-how. You bring the idea.

A FEW GOOD QUESTIONS

Before you
move in.

Small app. No big mysteries.

Is Nook really free?

Yes. Nook is free and open source under the MIT license. Use it, change it, and share it. There’s no subscription or Nook account. Optional services you connect, such as Groq for dictation, use your own API key and may have their own costs.

Will it work on my Mac?

Nook runs on macOS 14.2 or later, on Apple silicon and Intel. It works on Macs without a notch, too, by adding a virtual one at the top of the screen. External monitors are welcome.

macOS says it can’t verify the developer.

Nook isn’t notarized yet. After moving it to Applications, right-click Nook and choose Open. If macOS still blocks it, try opening it once, then go to System Settings → Privacy & Security → Open Anyway and confirm.

What permissions does Nook need?

Accessibility enables global shortcuts and pasting dictated text. Microphone lets you record dictation. Audio capture lets the volume mixer control sound per app. Dictation sends audio to Groq for transcription and uses AI for optional cleanup.

How do plugins work?

Each tab is a folder with HTML, JavaScript, and a plugin.json manifest. Nook loads it at runtime and reloads it when you edit a file. The window.nook bridge provides native features, including shell access, so only install plugins you trust. Build one yourself, or ask Claude Code or Codex to help. Read the plugin docs
