Hide YouTube spoilers by keyword, score, or channel. Blocks thumbnails and titles with an overlay until you choose to reveal. 🛡️ Spoiler Shield — Hide YouTube Spoilers Before They Ruin It You queued up the game. You're saving the match for tonight. Then you open YouTube — and right there in the sidebar, a thumbnail screaming "3-1 COMEBACK" with a shocked face. Gone. Ruined. Spoiler Shield fixes this. HOW IT WORKS Spoiler Shield scans YouTube video cards and covers any matching video with a full overlay — thumbnail, title, hover preview, everything hidden. You see a shield instead. When you're ready to watch, click Show to reveal it. WHAT IT BLOCKS 📺 Channel blocking — Block entire channels by name. Every video from that channel gets hidden, no matter what the title says. Perfect for channels that always spoil results in their thumbnails and titles. 🔢 Score patterns — Automatically detects match scores like "3-1", "4:0", "2–2" in any title. No setup needed. 🔤 Spoiler keywords — Built-in list of common spoiler words (wins, eliminated, champion, finals...) with a single toggle. Add your own custom keywords too — either exact match (whole word) or contains (anywhere in the title). FEATURES Full overlay: thumbnail + title + hover preview all blocked Channel blocklist: hide everything from specific channels Built-in score detection (regex-based, works for any sport) Built-in spoiler keyword list Custom keywords: exact word or partial match, per keyword Works on homepage, search results, watch page sidebar, and channel pages Master on/off toggle Reveal with one click — hide again if you change your mind 100% local — no servers, no accounts, no data collection, no AI PERFECT FOR Sports fans watching matches on delay Esports viewers who follow competitive seasons Anyone who hates YouTube's algorithm spoiling things in the sidebar PRIVACY Spoiler Shield stores your settings locally on your device using Chrome's built-in storage. Nothing is sent anywhere. Ever.
