Closed beta · Coming soon

A Mac browser
for the way you actually browse.

Spaces, split view, per-site shield, live tab previews, and a fuzzy command palette that finds anything. Built on Chromium so every site just works. Native to macOS, made for your Mac.

The parts you'll use every day

A browser that respects your attention.

Small things that add up — the difference between a Chromium reskin and a tool that feels like home.

Spaces

Life in tabs,
not chaos in tabs.

Separate contexts for work, side projects, research, and the rabbit holes you're not proud of. Each space has its own color, icon, gradient theme, and auto-sleep policy. Switch with ⌘⌃1–6; drag pills to reorder.

  • Up to 6 spaces
  • Per-space themes
  • Aggressive auto-sleep
  • Drag-reorder
Tab groups

Color-coded, collapsible,
drag-to-reorder.

Collapse 20 research tabs to a single pill. Pick a color, give it a name — or let on-device AI pick one for you based on what's inside. Reshuffle by dragging; move tabs in and out as the project evolves.

  • Per-group color
  • Collapsible
  • AI-named
  • Drag-reorder
Shield

Ads, trackers, and cookie
banners — gone.

Ghostery's filter lists running in-process at the network layer. EasyList + EasyPrivacy + Fanboy cookie banners. Per-site pause when a page needs it. A live counter in the toolbar shows what you're not loading.

  • EasyList
  • EasyPrivacy
  • Cookie banners
  • Per-site exceptions
Command Palette

One shortcut,
everything at once.

⌘K opens a fuzzy search across actions, open tabs, history, bookmarks, and settings. Type a few letters — arrow keys navigate, Enter activates. No context switching, no menu hunting.

  • Fuzzy match
  • Switch to open tab
  • Jump to settings
  • Bookmarks & history
On-device AI

Your AI,
your model, your Mac.

Nook names your tabs and groups without ever touching the cloud. Default to Apple Foundation Models — free, fast, offline. Prefer something bigger? Point Nook at your local Ollama and pick any model you've pulled: Llama, Qwen, Mistral, GPT-OSS. Every AI call stays on your machine.

  • Apple Foundation Models
  • Ollama (pick your model)
  • Offline
  • Zero telemetry
Split view

Two tabs, one window.
Your docs next to your code.

Pair any two tabs side-by-side with ⌘⌥\. Real split panes — each tab keeps its own page, its own audio, its own everything. Close one side and the other takes the full width again.

  • 50/50 split
  • Independent audio
  • One shortcut to toggle
And more

The rest of what Nook does.

Every feature below is built in — no extensions to install, no settings buried three menus deep.

Live tab previews

Every tab you've touched gets a live thumbnail. Hover in the sidebar, a card slides out with a fresh snapshot + title + URL. No more "which tab was that again?"

Customizable top to bottom

Per-space gradient themes, four alternate app icons, vertical or horizontal tab layout, pick your search engine (Google, DuckDuckGo, Kagi, Bing, or a custom template). Your browser, your rules.

Chrome extensions — real ones

Full Chrome Web Store install flow, not a bolted-on subset. 1Password, Dark Reader, Raindrop, Bitwarden, React DevTools — anything built for Chrome runs here. That's the whole reason Nook uses Chromium instead of WebKit.

Smart sleep

Background tabs release their renderer process after 30 minutes idle (or 5 min on aggressive spaces). Memory stays low, tabs wake instantly on click, and the scroll position + video timestamp come back where you left them.

Import from anywhere

Bookmarks + open tabs from Chrome, Safari, Arc, and Dia. First-run onboarding walks you through it; a few clicks and your spaces come over. Imported tabs start sleeping so they don't slam your Mac.

Trackpad gestures

Two-finger swipe left or right on any page — back and forward, with Chromium's native rubber-band animation. No shortcut to remember; it works the way Safari's always has.

Privacy without effort

Incognito windows run in a disposable session — zero disk, zero history, zero extensions attached. Shield exceptions are per-site and persistent. Permissions (camera, mic, location) prompt once, remember forever, revokable anytime.

A few honest words.

Nook is in closed beta while we polish the rough edges you'd otherwise have to ignore. Invites go out in small batches — join the waitlist and you'll get one as soon as a slot opens.

No telemetry, no usage tracking, no email list beyond this one. Nothing leaves your Mac unless you ask it to — the privacy page has the short version.

One email, one heads-up when your invite is ready. No newsletter, no drip campaign. You'll hear from us exactly once.
