Is your plugin public? Some friends and I were lamenting the AI-ification of HN, so is use anything that filtered it down in a heartbeat.

No, but here's the tiny bit of code I just use. Improve as you please.

bad-ai.js

const bad_words = [ " ai", "ai ", "a.i.", "openai", "llm", "agentic", "claude", "large language models", "apple intelligence" ]

var elements = document.body.getElementsByClassName("titleline");

for (var i = 0; i < elements.length; i++){ var element = elements[i]; var text = element.children[0].text.toLowerCase();

    bad_words.forEach(word => { 
        if( text.indexOf(word) > -1 ){
            console.log("Bad-AI remove: " + text)
            element.parentElement.parentElement.nextSibling.style.display = "none";
            element.parentElement.parentElement.style.display = "none";
        }
    });

}
