How do I block ChatGPT on Chrome for free?

Install a free blocker like Focuh from the Chrome Web Store, add chatgpt.com and chat.openai.com to your blocklist, and start a challenge. It takes under a minute and needs no account. Any ChatGPT tab then redirects to a quiet local page and the extension counts how often you tried to open it. That covers the ChatGPT website in Chrome, but it won't touch the ChatGPT desktop app or other browsers.

What domains do I need to block for ChatGPT?

ChatGPT lives on two hostnames. The current one is chatgpt.com, and the older one, chat.openai.com, still redirects there. Add both so a stray bookmark or old link doesn't slip through. If your goal is to block AI chat tools as a category rather than just ChatGPT, you'd also add claude.ai, gemini.google.com, and copilot.microsoft.com. A blocker that matches on the hostname covers each domain and its subdomains.

Will a Chrome extension block the ChatGPT desktop app?

No. A Chrome extension only controls Chrome tabs, and the ChatGPT desktop app for macOS and Windows is a separate program that runs outside any browser. Blocking chatgpt.com in Chrome does nothing to the standalone app. If you've installed the desktop app — or you trigger it with a keyboard shortcut — a browser block leaves it wide open. For that you need system-level blocking like the Focuh Mac app.

Does blocking ChatGPT in Chrome also block it in Edge or Arc?

Only if you install the extension there too. A Chrome extension runs in Chrome alone. Focuh is a Chromium extension, so it also works in Edge, Arc, Brave, Vivaldi, and Opera, but you install it separately in each because extension storage is per-browser. Firefox uses a different extension format entirely. If you bounce between browsers, an extension in one of them won't cover the rest.

Should I block ChatGPT if I use it for work?

Block it during the work you want to do yourself, not all day. ChatGPT is genuinely useful, but it's easy to reach for it as a first move on every hard problem, which dulls your own thinking and pulls you into long side-quests. A timed block during deep-work sessions keeps it out of reach while you draft or reason, then lets it back for the tasks where it actually helps.

Can I still open ChatGPT if I need it?

Yes. Any Chrome extension can be turned off from chrome://extensions, so you can disable the block, use ChatGPT, and re-enable it. That's intentional — a free extension interrupts the autopilot habit of opening ChatGPT rather than locking you out for good. If you want blocking that's genuinely hard to lift mid-session, that lives at the OS level, not in a browser extension.

How long should I block ChatGPT for?

Long enough to break the reflex of reaching for it. Focuh runs challenges of 30, 91, or 180 days, or a custom range, rather than an hour at a time. Opening ChatGPT the second a task feels hard is a habit built over months, so a single afternoon rarely sticks. A 30-day challenge gives the reflex time to fade, and the attempt counter shows how often the urge actually fires during a normal week.

How to Block ChatGPT on Chrome (Free, No Account) — 2026

June 10, 20268 min readFocuh

If ChatGPT has quietly become your first move on every hard problem — the thing you open before you've even tried to think — a blocker can hand the thinking back to you. This guide shows how to block ChatGPT on Chrome for free, in about a minute, with no account. It's also honest about the gap that trips people up: an extension only blocks Chrome, and ChatGPT now ships a desktop app that lives outside the browser entirely.

The fast answer

To block ChatGPT on Chrome for free, install Focuh from the Chrome Web Store, add chatgpt.com and chat.openai.com to your blocklist, and start a challenge. Every ChatGPT tab then redirects to a calm local page, and the extension counts your attempts so you can watch the habit fade. There's no account, no 3-site cap, and no telemetry. The catch: this blocks the ChatGPT website in Chrome, not the desktop app or other browsers.

How to block ChatGPT on Chrome step by step

Open the Chrome Web Store and search for Focuh, or go to the Focuh extension page.
Click Add to Chrome, then Add extension. No account, no email.
Click the Focuh icon and add chatgpt.com and chat.openai.com to your blocked sites.
Pick a challenge length — 30, 91, or 180 days, or a custom number — and start it.

From that point, any attempt to load ChatGPT in Chrome redirects before the page renders. You don't get a flash of the chat box first. Each attempt bumps a counter, which is oddly clarifying: most people are surprised how reflexive the habit has become once they can see the number climb.

Which domains does ChatGPT use?

ChatGPT has moved between hostnames, so blocking one isn't always enough. The current address is chatgpt.com. The older chat.openai.com still works and redirects to the new domain, so a saved bookmark or an old link in your notes can route around a partial block. Add both.

If your real aim is to stop all AI chat tools from becoming a crutch, treat it as a category. Add claude.ai, gemini.google.com, and copilot.microsoft.com alongside ChatGPT. Focuh matches on the hostname, so each entry covers that domain and its subdomains — block the category once and you're not playing whack-a-mole every time you discover another tab you've been opening.

The catch: a Chrome extension can't block the ChatGPT app

Here's the part most "how to block ChatGPT" guides skip. ChatGPT isn't only a website anymore — there's an official desktop app for macOS and Windows, and it can be summoned with a keyboard shortcut without ever touching a browser. A Chrome extension controls Chrome tabs and nothing else. Block chatgpt.com in Chrome and the desktop app opens exactly as before.

So a Chrome-only block works in one specific case: you only use ChatGPT in a browser tab and haven't installed the app. If that's you, the extension is genuinely enough. If you've got the desktop app, or you switch to Safari or Edge when Chrome blocks you, the website block alone is closing the front door while the back door stays open.

Free ways to block ChatGPT on Chrome, compared

Method	Free?	Blocks web	Blocks desktop app	Blocks other browsers	Setup time
Focuh extension	Yes	Yes	No	No	~1 min
StayFocusd	Yes	Yes	No	No	~3 min
Hosts file edit	Yes	Yes	Partial	Yes	~10 min
Focuh Mac app	Yes	Yes	Yes	Yes	~3 min

The only rows that reach the desktop app aren't Chrome extensions at all. That's the whole trade-off: an extension is the fastest way to block ChatGPT in your browser, but by definition it can only block the browser.

How do I block the ChatGPT desktop app?

If your ChatGPT habit lives in the native app, you need to block below the browser. On a Mac, the free Focuh desktop app does this with macOS Accessibility APIs — during a focus session it blocks both chatgpt.com across every browser and the ChatGPT app itself, and it's harder to switch off mid-session than an extension because it doesn't sit in chrome://extensions.

The full walkthrough for the app side, including the hosts file and SelfControl methods, is in how to block ChatGPT on Mac. The most reliable setup is both layers: the free Focuh Chrome extension for tabs, plus the free Focuh Mac app for the desktop app and other browsers. Both are free, so running both costs nothing.

Why block a tool you use for work?

ChatGPT is useful, which is exactly why this is worth thinking through rather than treating it as just another distraction. The problem isn't the tool — it's the reflex. When opening ChatGPT becomes your first move on every hard task, you stop sitting with problems long enough to form your own answer. You outsource the messy first draft, the stuck moment, the slow reasoning that's actually where the work happens.

A block doesn't ban ChatGPT from your life. It carves out the stretches where you want to think for yourself — drafting, debugging, reasoning through a decision — and keeps the tool out of reach until you're done. Then you let it back for the tasks where it genuinely saves time. If ChatGPT is one of several leaks, the same approach scales to your whole list, the way you'd set up any free Chrome blocker.

Which option should you pick?

You only use ChatGPT in a Chrome tab — install the Focuh extension, add chatgpt.com and chat.openai.com, start a challenge.
You have the ChatGPT desktop app — add the free Focuh Mac app and follow the block ChatGPT on Mac guide.
You switch to Safari or Edge to get around the block — you need system-level blocking, not a single-browser extension.
You want to block AI chat as a category — add claude.ai, gemini.google.com, and copilot.microsoft.com to the same list.

No blocker fixes focus on its own, and a Chrome extension can't fix the ChatGPT app — be honest about which one you actually open when a task gets hard. Install Focuh free for the browser, and get the free Mac app if the desktop app is where ChatGPT really eats your attention.
