ElementHider: Hide, Blur, Highlight, or Replace Content by Keyword

Tired of spoilers, distracting sidebars, and web clutter you didn't ask for? ElementHider puts you back in control. Type in the words and phrases you want to avoid, and matching content disappears — instantly, on every page.

Free to use — no account, no sign-up.

★ Features

Hide by Keyword — Filter out spoilers, annoying topics, or anything you'd rather not see. If a section of a page contains your keyword, it's gone.

Point & Click Hiding — Keywords not enough? Click directly on any element — an annoying sidebar, floating banner, or "suggested for you" box — to create a rule that hides it everywhere.

Blur Mode — Prefer a softer approach? Blur content instead of removing it entirely, and hover to reveal when you're ready.

Built for Dynamic Sites — Hides content as new posts load while you scroll. Works on YouTube, X (Twitter), Facebook, Reddit, news sites, shopping feeds, and more.

Site-Specific Rules & Precision — Apply filters everywhere, or limit them to specific websites. Adjust hiding sensitivity, use exact-match or case-insensitive matching, and use Test Mode to preview what will be hidden before it disappears.

Smart Suggestions — ElementHider notices when a keyword is missing variations — different capitalizations, plurals, word endings — and flags it with a one-click fix right in the popup. Nothing slips through the cracks.

★ Supporter Pack

Unlock advanced features with a single contribution — no subscription, yours forever:

Groups — Bundle related keywords by topic (e.g. Sports Season, TV Spoilers) and mute an entire category with one switch.

Highlight Mode — Make matches glow with a soft color instead of vanishing — scan headlines safely.

Replace Mode — Fill hidden content with your own placeholder like [Spoiler] — no awkward blank gaps. Or replace just the matched word inline, leaving the rest of the sentence untouched.

Regexp / Pattern Matching — One rule covers every variation: spoiler, SPOILER, spoilers, all at once.

Dark Mode — A night-friendly theme for the extension UI.

Smart Learning — Stop managing endless lists of keywords one by one. A private, on-device engine watches the context around what you hide, learns the words that tend to show up alongside it, and starts catching related mentions automatically — cutting down on both missed matches and false positives. Its learning data never leaves your device.

Private & Secure
ElementHider scans the pages you visit for your keywords locally, in your browser. Your keywords and settings are stored in your browser's own sync storage — never sent to us.

If you choose to unlock the Supporter Pack, you'll optionally provide your email address to verify your Ko-fi contribution. That email is stored securely on our server solely to confirm your supporter status — nothing else. Full details in our Privacy Policy.
