AiBlock for YouTube

Block YouTube channels that use AI-generated content

Filter AI-generated content on YouTube. Community-powered blocklist with customizable warning and hiding modes. Youtube is drowning in AI-Slop. Thousands of channels, uploading videos, with AI scripts, audio or visuals. This is why I created this extension. It will help you, cleaning up your feed by providing personal filterlists and a list, maintained by the community. How It Works 1. Install the extension 2. Community blocklist syncs automatically on first launch 3. Browse YouTube - AI channels are filtered based on your settings 4. Right-click any channel to add to blacklist, warnlist, or whitelist 5. Customize your experience in the extension popup You can find us on github and discord if you want to support or just out of curiosity. Features - automatically synched community blocklist (can be disabled) - manually black, warn or whitelist channels - view statistics of lists and blocked videos - import/export your own lists ***** Version 1.1.6 -------------------------- New - Banner Mode setting — You can now control the "AI-flagged by YouTube" banner from the Preferences tab with a simple three-way switch: Off — never show the banner AI — show only when YouTube says a video was made with AI (default) All — also show for YouTube's "altered or synthetic content" label - Keep training your own feed on blocked sidebar videos — When a suggested video on the right of the player is blocked, the overlay now leaves a small rounded gap in its bottom-right corner so YouTube's own "⋮" menu stays clickable. You can still tap "Not interested" / "Don't recommend channel" to teach YouTube your preferences, while still seeing that the extension flagged it. Improved - The AI-flag banner is much less in-your-face — Redesigned from a big bright-orange bar into a slim, dark, semi-transparent banner that blends into YouTube, with quieter buttons. - Tidier settings — The Preferences tab is more compact, so everything fits without a scrollbar. Version 1.1.5 (1.1.4 firefox only) -------------------------- Fixed • Prevent duplicate submissions • Prevent submission of already covered channels (blocklist) • Faster channel Home-tab blocking • Live settings/popup updates • Consistent channel storage New • Keyboard shortcuts to report the hovered channel • AI and synthetic content disclosure banner Changed • Recently-submitted memory raised 50 → 150 Version 1.1.3 -------------------------- Fixed • No more double overlays: blocked videos no longer show two stacked "Blocked" overlays. • Channel cards in search now get blocked reliably: previously a blocked channel could appear in search results without an overlay. • Indexing issue fixed: overlays now stay within their video tile and can't escape above YouTube's navigation bar. • Right-click "Block this channel" on Shorts and sidebar videos now blocks the correct channel. Previously it could store the handle in a form that didn't match other videos from the same channel. • Context menu items no longer disappear or duplicate after Chrome restarts the extension in the background. • Shorts feed now uses the same channel matching as the main feed, so community-list channels won't slip through on Shorts. • After navigating between YouTube pages, leftover timers from the previous page can no longer fire and cause odd overlay flickers. New • In-player suggestions are now blocked: the video thumbnails YouTube shows at the end of a video (endscreen suggestions) are now covered by the same overlay as regular feed videos. • Added support for YouTube's newer channel-page layout so blocking keeps working as the redesign rolls out. • Added support for newer channel-card layouts in search results. • Added option for automatically block submitted channels until approved Performance • Hiding a full page of videos is now noticeably lighter on your browser • Large community lists use roughly 6× less memory for the lookup table. • Overlay cleanup is faster and more reliable when YouTube reuses video tiles while you scroll. Privacy • The popup no longer loads fonts from Google. The DM Sans font is now shipped inside the extension, so opening the popup makes zero network requests to third parties. • Added a strict Content Security Policy to the extension's own pages as a defense-in-depth measure.
