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 content required for 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.
• Revisions to Google search filters
• X: Posts made by @Grok.
• Zoom: Highlights and automatic chapters on recorded meetings.

FAQ

Which adblockers will this filter list work with?

These filters were developed for uBlock Origin and AdGuard, but they should also work with AdBlock, Adblock Plus, and Brave's integrated adblocker.

Will this remove sites that post AI generated content from search results?

No. If you want to block AI sites from search engines, try laylavish's Huge AI Blocklist.

Can I use these filters with Pi-hole?

No. Pi-hole and uBlock Origin work differently. uBlock Origin allows filtering individual elements on pages, while Pi-hole blocks entire domains.

Can I use these filters with Opera?

No. These filters do not work with Opera's built-in adblocker or uBlock Origin for Opera. The built-in adblocker doesn't allow importing custom filter lists via URL while uBlock Origin for Opera didn't filter correctly when testing. (This may be an issue with Opera)

Why are AI Overviews still showing up on Google?

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

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. 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 of search engines?

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.

How many websites have filters for AI features?

Over 300.

Where can I find a full list of filtered items?

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

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

A small number of filters use features that require trusted origin filters in uBlock Origin. Trusted filters are disabled by default in uBlock Origin for security reasons, as they allow directly executing code on webpages.

This list requires trust to:

• Replace "Search or ask a question" text on GitHub Docs and YouTube.
• Remove the "AI sparkle" from search icons.
• Remove automatic audio dubbing on YouTube videos if they were directly loaded from a URL. (in Extra filters, see below FAQ entry).

To be clear, if you use uBlock Origin, you do not need to mark this list as trusted to use a majority of the AI filters. However, if you want to use the filters listed above, you can go to uBlock Origin's advanced settings and add https://raw.githubusercontent.com/Stevoisiak/Stevos-AI-Blocklist/refs/heads/main/ to trustedListPrefixes.

Why are trusted filters recommended in AdGuard but not uBlock Origin?

Some filters use scriptlets to block AI items. (YouTube autodubbing, TikTok videos with AI, etc). In uBlock Origin, trusted filters are only needed for scriptlets that start with trusted-. However, in AdGuard trusted filters are required for all scriptlets. Also, it's easier to enable trusted filters in AdGuard compared to uBlock Origin.

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.
