⚡ Declutter X in one click
DashBlocker automatically hides any post or reply that contains an em-dash (—) which is a common tell for AI-generated text. Install, refresh, and enjoy a cleaner timeline.
🔑 Key features
• Real-time filtering: tweets disappear the moment they load.
• Toggle anytime: flip the switch in the popup without reloading the page.
• Stats counter: see how many posts DashBlocker has nuked for you.
• Zero setup: no accounts, no config files—just install and scroll.
• Open source & lightweight: <10 KB of code and no tracking.
🔒 Privacy first
DashBlocker never sends data off your computer. The only thing it stores is a counter of tweets you’ve hidden, saved locally via Chrome Sync.
🛠️ Geek details
• Manifest V3, no remote code, minimal permissions (storage only).
• Works on x.com and legacy twitter.com URLs.
• Regex: `/\w—\w/` (word-bound em-dash) for speed and accuracy.
