The extension simply reads the 'Altered or synthetic content' label provided by YouTube. If a video was flagged, it's because the creator disclosed it as such in their settings. I never promised the extension would perform its own AI analysis; it accurately reports the data YouTube provides.

Can you please provide a link to the video in question so I can investigate if this was a genuine bug or simply a case of the creator labeling their own work as synthetic?

That feature would be great, but this extension is designed to read the 'Altered' labels YouTube only shows once a video page loads. Hiding them from search results would require a different method, like using a database of known AI channels to block them before you click.

Check out 'AI Channel Blocker for YouTube' (https://addons.mozilla.org/en-US/firefox/addon/ai-channel-blocker-for-youtube/). I haven't tried it myself, but it uses a human-curated list to block known AI channels and may be what you're looking for.

Glad it's been helpful!
