How to Block AI Content: The Complete Guide

AI-generated images, articles, and videos are everywhere: search results, social feeds, marketplaces, even family group chats. If you want less of it, you have real options. This guide covers every way to block AI content, from one-click browser blocking to platform settings and site-level bot rules.

Block AI Images in Your Browser

The fastest fix works everywhere at once: a browser extension that detects AI images and blurs them before you see them.

Add AI Blocker to Chrome from the Chrome Web Store. It's free.
Browse normally. Every image on every page is checked for AI automatically.
Images detected as AI-generated get blurred with a label. Click any blurred image to reveal it.

Detection is powered by AI or Not, which analyzes each image for the patterns AI generators leave behind. That's different from blocklists and keyword filters: it works on brand-new accounts and sites no list has caught up to yet.

Block AI on Specific Platforms

Some platforms offer built-in AI labels and filters, and they differ a lot. We keep a current guide for each of the big ones:

How to block AI on Pinterest (AI-modified labels, "see fewer" controls, and automatic blurring)
How to block AI content on YouTube (synthetic-media labels and channel-level controls)
How to block Meta AI (what you can and can't turn off on Facebook, Instagram, and WhatsApp)

Block AI in Google Search Results

Google's AI Overviews sit on top of many searches. There's no permanent account-level off switch, but the Web filter shows link-only results, and a URL trick makes that the default. Our Google AI Overviews guide walks through each method.

Block AI Bots From Your Own Website

Blocking works in the other direction too. If you publish content and don't want AI companies scraping it for training, you can name their crawlers in robots.txt and enforce the rules at the CDN level. Our AI bots guide includes a copy-paste robots.txt for the major AI crawlers.

Check Text, Audio, and Video for AI

Images get blocked automatically, and the rest is one action away. With AI Blocker installed you can highlight any text on a page to check whether it reads as AI-written, and upload audio or video for detection. Uploads are deleted immediately, and checks aren't stored.

Block AI content in one step

AI Blocker checks every image on every page you visit and blurs the ones detected as AI-generated. Free on the Chrome Web Store, powered by AI or Not.

Blocking AI Content FAQ

How do I block AI content?

The most reliable way is a detection-based browser extension. AI Blocker checks every image on the pages you visit and blurs the ones detected as AI-generated, on every site. Platform-specific controls, like AI labels on Pinterest or the Web filter on Google, help on individual sites.

Can I block all AI-generated content?

Not completely. Detection is probabilistic, and text, audio, and video each need their own checks. But an AI blocker catches most AI images automatically, and you can check text by highlighting it and audio or video by uploading it.

Is there a free way to block AI images?

Yes. AI Blocker is free to install from the Chrome Web Store and blurs detected AI images automatically, powered by AI or Not's detection.

Can I block AI from using my website's content?

You can ask AI crawlers to stay away with robots.txt rules for bots like GPTBot and CCBot, and enforce it with CDN or firewall-level bot blocking. See our guide to blocking AI bots for the exact steps.
