X Read Marker
A calmer X timeline. Posts you have already read quietly fade, fresh ones stand out, promoted posts disappear, and Focus Mode clears the clutter around the feed. Everything is computed on your device — the extension makes zero network requests.
Features
- Read posts fade automatically
- Promoted posts hidden
- Focus Mode on by default
- Reading stats, stored locally
- Light and dark, follows your system
- Works offline
Why we built it
Scrolling X means re-reading the same posts over and over, because nothing marks what you already saw. Every existing fix wanted an account and a server. This one keeps the record in your own browser and never sends it anywhere.
