Your agent’s, too.

How we measured

October 20, 2026 · Apple M4 Pro · macOS 26.0. Both browsers navigated to the same local form, filled three fields, selected an option, checked a box, submitted, and verified the saved result. Same 870 × 262 viewport; two warmups per browser excluded.

Browser API execution only; excludes AI thinking, setup, and app startup. Notch used its JavaScript client; Codex used its in-app Playwright API. Different automation drivers, one local task. Results vary by workflow.

Download timing data

  • Already signed in.

    Your agent uses real tabs and your existing sessions. No separate browser profile to set up.

  • Works in the background.

    Keep the notch collapsed while your agent works. Run tasks in two independent tabs at once.

  • Reads what matters.

    Extract text, links, and media. Get focused page snapshots, with support for embedded frames.

  • Acts on the page.

    Click, fill forms, select options, and upload files you choose. Everyday browser tasks, ready for your agent.

  • More than text.

    Capture screenshots and video frames, or open a local HTML result right in the notch.

  • Always in your control.

    See agent activity, stop or resume control, and take over whenever a site needs you.

For background tasks, keep the app running and your Mac awake.

Set up your agentCLI + skills included

One setup.
Then just ask.

The CLI, JavaScript client, and agent skills come with the Mac app. Connect once, then ask for what you need in plain language.

  1. Install and activate Notch Browser.
  2. Run the setup command for your agent.
  3. Start a new agent session and ask.
Download the agent skill

Paste this into Terminal once:

Terminal
cd "/Applications/notch-browser.app"
./Contents/Helpers/notch-browser setup codex

Installs the CLI and your chosen agent skill.

Then start a new agent session and ask:

“Use Notch Browser to find the WebKit docs. Work in the background.”

What gets installed?
CLI
~/.local/bin/notch-browser
Skill
~/.codex/skills/notch-browser

Codex uses your configured CODEX_HOME folder when set. Other agents with shell access can use the CLI directly.

Command not found?

Keep ~/.local/bin on your PATH, or call the CLI with its full path:

~/.local/bin/notch-browser status --json

If you moved or renamed the app, update the app path in the setup command.

A little browser for the quick stuff.

Look it up.
Get back to it.

Quick lookups, docs, and your everyday 4–5 tabs. Tucked into your Mac’s notch, one hover away.

Preliminary local tests · Apple M4 Pro, 24 GB. Background CPU measured with five hidden, idle tabs. Results vary.

Behind the numbers
  1. Memory. Five public websites in each browser, including app and helper processes. Median of three trials on October 14, 2026. Chrome 155.0.8059.40. Memory measurements ↗
  2. Background CPU. Median paired reduction versus Chrome across three preliminary five-tab background trials on October 16, 2026. The same five websites were loaded in each browser, then kept hidden and idle for 60 seconds after a 20-second settling period. Counts each browser’s own app and helper processes. Chrome used a separate test profile; unrelated Chrome processes were excluded. Notch 1.0 (Debug build); Chrome 155.0.8059.84. This measures background CPU use, not active browsing or battery life. Short-lived processes between samples may be missed. CPU measurements ↗
  3. App size. Installed bundles: Notch 11.1 MB; Chrome 1.5 GB. Excludes website data, caches, and shared macOS frameworks, including WebKit. Measured October 15, 2026.
  4. Startup. Median of five fresh launches to a fully loaded local test page, with warm system caches. Includes panel opening and automation overhead. Measured October 15, 2026. This measures Notch startup, not website loading speed.

Good to know.

How do I download and activate Ink?

Download Ink, open the disk image, and drag notch-browser into Applications. Buy a license, then copy your key from your Polar purchase email or customer portal and paste it into the app. The Mac app is currently named Notch Browser.

Already purchased?

You can download Ink again using any Download link on this page. Your license key is in your Polar purchase email and customer portal. If you don’t see the email, check your spam folder.

How many tabs can it handle?

There’s no fixed tab limit. Keep the tabs you need close by, though Notch Browser is designed for a focused handful of everyday tabs rather than dozens of heavy pages. How many run comfortably depends on your Mac and the sites you open.

Do I need to sign in to every site again?

Chrome import can bring over your cookies and signed-in sessions during setup, so you don’t have to start from scratch. Some sites may still ask you to sign in again. Safari currently imports bookmarks; you’ll need to sign in to those sites again.

Can it launch at login?

Yes. Turn on Launch at Login in the app’s menu and Notch Browser will be ready when you sign in to your Mac.

Can I embed any web app into the notch?

Yes. Open your web app and switch to Embed mode to hide the browser controls. Your AI chat, music player, notes, or documentation can stay in the notch, just a hover away.

How is it agent native?

The included CLI and skills let Codex, Claude Code, or another agent with shell access use your real Notch Browser tabs. Agents can read and extract page content, click, fill forms, upload chosen files, interact with embedded frames, capture screenshots, and open local HTML. Keep the app running and your Mac awake, even when the notch is collapsed.

Set up your agent
Can I take over while an agent is browsing?

Yes. The app shows agent activity and lets you stop control. If a site needs a CAPTCHA, sign-in verification, or camera or microphone permission, your agent can reveal the tab and hand it back to you. Complete the step, then press Resume in the app. These steps need your input.
