☢️ emnuke

Nuke em-dash content from the web.

Em dashes are the fingerprint of AI slop. emnuke is a browser extension that finds them and blows them up with a nuclear animation.

🎬 Demo video coming soon

Modes

Mode	What it does
☢️ Nuke	Animated removal as you scroll. The fun one.
🔇 Filter	Silent removal. Poof, gone.
🔍 Highlight	Orange border on suspicious content. Nothing removed, just shamed.
💤 Off	Extension is idle.

Exclude sites

Some sites needs em dashes (like, claude.ai). Click the extension icon on any page and hit Exclude [hostname]. Click again to un-exclude. Persists across reloads.

What gets nuked

We don't just blindly nuke the whole page. Each site gets precise targeting so we kill the right content block.

Site	What gets nuked
Google	Search results, news cards, video results
Reddit	Posts, search results, ads. Comments get redacted but replies survive.
Twitter/X	Individual tweets
LinkedIn	Feed posts
Bing, DuckDuckGo, Brave, Ecosia, Kagi, Startpage, Yandex	Search results (selectors pulled from uBlacklist)
Everything else	Paragraphs, list items, headings, whatever contains the crime

More sites coming. PRs welcome.

How it works

1. MutationObserver watches the DOM for new content
2. TreeWalker hunts for the em dash character (U+2014)
3. findContentBlock walks up the DOM to find the right thing to destroy
4. In nuke mode, IntersectionObserver waits until you scroll to it, then boom

Search engine selectors are fetched from uBlacklist's configs and cached for 7 days. They update themselves. You don't have to do shit.

Development

pnpm install
pnpm dev            # Chrome with hot reload
pnpm dev:firefox    # Firefox with hot reload
pnpm build:all      # Build Chrome, Firefox, Edge, Safari, Opera

See CONTRIBUTING.md for how to add support for new sites.

"But isn't this anti-AI?"

No. AI-assisted creation can be cool. What's not cool is lazy bastards who copy-paste raw ChatGPT output and call it a day. If you can't even be bothered to clean up the em dashes, your content shouldn't exist on the internet. This extension just makes that happen automatically.
