This bookmarklet prompts for a comma-delimited list of terms (including phrases), scrapes existing terms to avoid duplicate errors, and offers the full updated list in an "I'm done" message. Play with the delay.

javascript:(function(){const delayMs=500;let input=prompt("Enter comma-separated muted keywords:");if(!input)return;const keywords=input.split(",").map(s=>s.trim()).filter(Boolean);const nativeInputValueSetter=Object.getOwnPropertyDescriptor(window.HTMLInputElement.prototype,"value").set;function getMutedKeywords(){let arr=[];document.querySelectorAll("section[aria-label='Section details'] div[role='link']").forEach(el=>{let span=el.querySelector("div[dir='ltr'] span");span&&arr.push(span.textContent.trim().toLowerCase());});return arr;}function addMutedKeyword(kw){const inp=document.querySelector("[name='keyword']");nativeInputValueSetter.call(inp,kw);inp.dispatchEvent(new Event("input",{bubbles:true}));document.querySelector("[data-testid='settingsDetailSave']").click();}const delay=()=>new Promise(r=>setTimeout(r,delayMs));keywords.reduce(async(prev,kw)=>{await prev;let existing=getMutedKeywords();if(existing.includes(kw.toLowerCase())){console.log("Skipping duplicate:",kw);return Promise.resolve();}let addButton=document.querySelector("a[href='/settings/add_muted_keyword']");if(!addButton){console.error("Add muted keyword button not found, skipping keyword:",kw);return Promise.resolve();}addButton.click();await delay();addMutedKeyword(kw);return delay();},Promise.resolve()).then(()=>alert("I'm finished.")).catch(e=>{console.error(e);alert("Finished with errors: "+e.message);});})();
