How do I block ChatGPT on my Mac?

ChatGPT is harder to block than a normal website because there's now a desktop app, not just the site. Blocking chatgpt.com in a browser does nothing to the Mac app. For a complete block you need a system-level tool that can block native apps — Focuh blocks both the ChatGPT app and the website during a focus session, and Cold Turkey can too. The hosts file and SelfControl block the website but may not stop the app launching.

Can I block the ChatGPT desktop app, not just the website?

Yes, but only with a tool that operates at the system level. Browser extensions and most basic blockers only touch chatgpt.com in the browser and leave the native ChatGPT app fully working. Focuh blocks the ChatGPT app directly using macOS Accessibility APIs, so the app is unreachable for the length of a focus session. Cold Turkey can also block apps. If you only use ChatGPT in a browser tab, a simpler web block is enough.

How do I block ChatGPT on Mac for free?

Several free options exist with trade-offs. The hosts file blocks chatgpt.com and chat.openai.com across all browsers but needs Terminal and doesn't reliably stop the desktop app. SelfControl blocks the website until a timer ends and can't be lifted early. Focuh is free and blocks both the ChatGPT website and the native app at the system level, tied to a focus timer. For the most thorough free result, use a tool that handles the native app.

What domains and apps do I need to block for ChatGPT?

For the website, block chatgpt.com and the older chat.openai.com, which redirects to it. For the app, block the ChatGPT desktop application itself — a website rule won't touch it. If you want to block AI chat as a category, add claude.ai, gemini.google.com, and copilot.microsoft.com too, plus any of their desktop apps. A system-level tool lets you list both sites and apps in one place.

How do I block ChatGPT only during focus sessions?

Use a blocker tied to a timer rather than an always-on rule. Focuh blocks ChatGPT only while a focus session runs — start the timer, the ChatGPT app and website are blocked, and they unblock when the session ends. This fits ChatGPT well because you often want it between focus blocks for tasks where it genuinely helps. Cold Turkey supports recurring schedules if you'd rather block fixed hours like 9am to noon.

Does blocking ChatGPT in Safari also block it in Chrome?

Only if you block at the system level. Screen Time's website limits mainly affect Safari and leave Chrome, Firefox, and Arc untouched. The hosts file, SelfControl, and Focuh all block chatgpt.com across every browser at once because they work below the browser layer. A single-browser extension blocks ChatGPT in that one browser only, so you could switch browsers and reach it again — which is why browser-only blocks tend to fail.

Can blocking ChatGPT be bypassed?

It depends on the method. Screen Time has a one-more-minute button and can be turned off with your passcode. A browser extension disables in two clicks. SelfControl is genuinely irreversible until its timer ends. Focuh's block can be lifted by revoking Accessibility permission in System Settings, which adds enough friction to stop an impulse but isn't a vault. Pick the friction level that matches how strongly you reach for ChatGPT.

Should I block ChatGPT if I rely on it for work?

Block it during the work you want to do yourself, not the whole day. Reaching for ChatGPT on every hard task dulls your own reasoning and pulls you into long detours. A timed block during deep-work sessions keeps it out of reach while you draft or think, then lets it back for the tasks where it actually saves time. You're not banning the tool — you're protecting the stretches where your own thinking matters.

How to Block ChatGPT on Mac (During Focus Time) — 2026

June 10, 20269 min readFocuh

ChatGPT is the distraction that looks like productivity. You open it to ask one quick question, and twenty minutes later you've outsourced the entire thinking part of a task you could have reasoned through yourself. This guide covers how to block ChatGPT on a Mac during focus time, with every free and paid method laid out honestly — including the part most guides miss, which is that ChatGPT now ships a desktop app that ignores browser blocks completely.

The fast answer

To block ChatGPT on a Mac properly, you need a tool that blocks the native ChatGPT app, not just the website — because the desktop app and its keyboard shortcut run outside any browser. The free Focuh Mac app blocks both chatgpt.com across every browser and the ChatGPT app itself during a focus session, using macOS Accessibility APIs. Start a timer, ChatGPT is unreachable until it ends, and you get your attention back without uninstalling anything.

Why ChatGPT is harder to block than a normal website

Most blocking guides assume the distraction is a website. ChatGPT broke that assumption when it shipped a desktop app. There's the site at chatgpt.com, but there's also a native macOS app that you can summon with a global keyboard shortcut without opening a browser at all.

That means a browser extension blocking chatgpt.com does precisely nothing to the app sitting in your dock or hiding behind a hotkey. You'll feel clever for "blocking ChatGPT," then hit the shortcut out of habit thirty seconds later. To actually block ChatGPT, you have to account for both the website and the native app — and only system-level tools reach the app.

How to block the ChatGPT app on Mac with Focuh

Download the Focuh Mac app and install it.
In Settings, add chatgpt.com and chat.openai.com to your blocked sites.
Add the ChatGPT app to your blocked apps list.
Grant Accessibility permission when prompted — a one-time setup.
Start a focus session. Both the ChatGPT website and the native app are blocked until the timer ends.

Because the block is tied to a timer rather than running all day, ChatGPT comes back the moment your focus block finishes. That fits how the tool actually earns its place: you want it for some tasks, just not while you're trying to think through a problem yourself. The same app-blocking approach works for any native distraction — the full pattern is in how to block apps on Mac.

Ways to block ChatGPT on Mac, compared

Method	Free?	Blocks web	Blocks ChatGPT app	All browsers	Timer-based
Focuh	Yes	Yes	Yes	Yes	Yes
Screen Time	Yes	Safari only	Partial	No	Schedule
Hosts file	Yes	Yes	Partial	Yes	No
SelfControl	Yes	Yes	Partial	Yes	Timer
Cold Turkey	Paid	Yes	Yes	Yes	Schedule

The split is the same one that shows up with any app-plus-website distraction: the methods that fully block the native ChatGPT app are the ones that operate at the system level. Browser-bound and Safari-only methods leave the desktop app as an open backdoor. For more on which Mac blockers handle native apps well, see the best free app blocker for Mac roundup.

The free methods, briefly

Hosts file. Open Terminal, run sudo nano /etc/hosts, and point chatgpt.com and chat.openai.com at 127.0.0.1. This blocks the ChatGPT website in every browser, though the desktop app may still launch and show a connection error rather than refusing to open. It's free and has no scheduling — it stays on until you manually undo it.

SelfControl. This free, open-source app blocks a domain list until a timer expires and can't be lifted early, even by rebooting. It blocks chatgpt.com across browsers through firewall rules, but like the hosts file, it disrupts the app's connection without necessarily stopping it from opening. It's the right tool when you want a block you genuinely can't argue your way out of.

Screen Time. Built into macOS and free, but its website limits mostly affect Safari, and the one-more-minute button makes the block trivial to bypass. It's designed for parental controls, not for someone deliberately trying to stay off a tool they find useful.

How do I block ChatGPT only during work hours?

You have two models, and they suit different people.

A timer-based block fits most knowledge workers. You block ChatGPT for the length of a single focus session — say 50 or 90 minutes — then it's back. This is the Focuh model, and it works because you rarely need an all-day ChatGPT blackout. You need protection during the stretches where you're actually building or reasoning, and free access the rest of the time.

A scheduled block suits people who want fixed deep-work hours. Cold Turkey can block ChatGPT every weekday from 9am to noon automatically. The trade-off is rigidity — a fixed schedule doesn't bend around a day where your deep work lands in the afternoon. If your week is unpredictable, a timer you start on demand beats a calendar rule you'll end up overriding.

What about blocking AI chat as a category?

ChatGPT is rarely the only AI tab open. If reaching for any chatbot has become the reflex, block the category instead of one app. Add claude.ai, gemini.google.com, and copilot.microsoft.com to your site list, and add any of their desktop apps to your blocked apps. A system-level tool like Focuh lets you list sites and apps together, so one focus session closes every door at once rather than redirecting you from ChatGPT straight into a different assistant. The reasoning behind blocking below the browser is in system-level website blocking on macOS.

Which method should you use?

You use the ChatGPT desktop app and want timer-based blocking — the free Focuh Mac app blocks both the app and the website during sessions.
You only use ChatGPT in a Chrome tab — a browser extension is enough; see how to block ChatGPT on Chrome.
You want a block you can't lift early — SelfControl, paired with quitting the ChatGPT app.
You want fixed weekday deep-work hours — Cold Turkey with a recurring schedule.

No blocker replaces the judgment of deciding when ChatGPT helps and when it's just a way to avoid thinking. But blocking the app during focus sessions removes the reflex to reach for it, and that reflex is what quietly costs you the deep work. Download Focuh free and give your next focus block a real shot at being your own.
