Extension Metadata

About this extension
Block unwanted content by keywords. Hide articles, videos, and posts with headlines you want to avoid. Free, private, no account needed. Your filtering choices power @Map, a global sentiment platform.

How it works
Add keywords to your filter list, and @Filter automatically hides articles, videos, and posts whose headlines contain those words. It works across news sites, social media, video platforms, and more.

Features
- Keyword-based filtering — block content by the words that matter to you
- Works everywhere — news sites, social media, YouTube, Reddit, and more
- Unlimited keywords — add as many filter terms as you need
- Instant setup — no account, no registration, just install and go
- Privacy-first — all filtering runs locally in your browser
- Lightweight — minimal permissions, no background tracking
- Community-powered — your anonymous filtering choices help build @Map, a global content sentiment platform

Privacy
@Filter processes everything locally in your browser. We don't collect your browsing history, don't track which sites you visit, and don't sell any information. The only data shared (with your consent) is anonymous, aggregated filtering patterns that power @Map.
