Optional extra blocklist

There is an additional optional filter list GenAI-Blocklist-Extra.txt with additional filters that are more subjective or experimental. They may be more prone to accidentally blocking non-AI content or breaking site functionality. These include:

• AI category in headers on news sites.
• Customer support chatbots that must be used before you can contact human customer support.
• YouTube: Trusted filter to remove autodubbing when loading a video directly via URL, but causes visible page refresh even on videos without autodubbing.
• Zoom: Highlights and automatic chapters on recorded meetings.
• Early versions of filters that require testing

FAQ

Which adblockers will this filter list work with?

These filters work best with uBlock Origin, AdGuard, or wBlock.

They should be usable with AdBlock, Adblock Plus, Brave, Ghostery, and the desktop version of uBlock Origin Lite, but they are not fully supported and may have compatibility issues.

Will this remove sites with AI-generated articles from search results?

No. If you want to block sites with AI-generated articles, try BadWebsiteBlocklist or just_a_husk's Image-Search AI Blocklist.

Can I use these filters with Pi-hole?

No. Pi-hole works differently from traditional adblockers. Adblockers allow filtering individual elements on pages, while Pi-hole blocks entire domains.

Can I use these filters with Opera?

No. These filters do not work properly with Opera's built-in adblocker or uBlock Origin for Opera. The reason why is unknown, but a similar issue was reported on Laylavish's blocklist.

How many websites have filters for AI features?

Over 500.

Why are AI Overviews still showing up on Google?

If you use AdBlock Plus, make sure "Show acceptable ads" is disabled in your settings.

How do I report a bug or an AI element that wasn't blocked?

Please submit an issue report.

Why is AdGuard recommended for Google Chrome and iOS instead of uBlock Origin?

uBlock Origin is not available for Google Chrome and iOS.

While uBlock Origin Lite exists as an alternative, it does not support custom filter lists on iOS. Support was added in uBO Lite for Chrome, but compatibility with this filterlist has not been thoroughly tested. A previous version of this README suggested copying the GenAI filters into uBO Lite's custom filters as a workaround. However, filtering was unreliable, updating required manually deleting the old filter rules, and some filter rules were incompatible.

Will this prevent AI summaries from being generated in the background?

Sometimes. This filter list was created with the primary goal of hiding AI elements, but some network filters have been added to prevent content generation.

Where can I find a full list of filtered items?

Check GenAI-Blocklist.txt and GenAI-Blocklist-Extra.txt.

Why are trusted filters recommended in AdGuard?

Some filters use scriptlets to block AI items. (YouTube autodubbing, DeviantArt & Pixiv image filtering, TikTok videos, setting cookies, etc). These filters will only work if the AI blocklist is marked as trusted.

Why do some filters show "Invalid filter: Filter requires trusted source" in uBlock Origin?

Trusted filters are disabled by default in uBlock Origin for security reasons, as they allow directly executing code on webpages.

To be clear, a majority of these filters will work in uBlock Origin without trusted filters, as most scriptlets are allowed by default. However, if you want to enable them, go to uBlock Origin's advanced settings and add https://raw.githubusercontent.com/Stevoisiak/Stevos-AI-Blocklist/refs/heads/main/ to trustedListPrefixes.

Why do YouTube videos still sometimes play AI dubbed audio tracks?

The filter for automatic dubbing on YouTube does not work when opening a video via direct URL. (IE: Entering the address directly in your browser's URL bar). It will work when clicking a video while already on YouTube, such as on YouTube's homepage, search results, or suggested videos.

The extra filter list has a filter that works when loading directly from URL, but it requires allowing trusted filters to run, (see above FAQ entry), and causes a visible page refresh whenever a video is loaded directly via URL.

Ads are appearing on YouTube after adding this filter

This was a known issue when using the AI Blocklist with Brave that should be resolved. If you are still seeing YouTube ads and have confirmed it only occurs when the AI blocklist is installed, please open an issue.
