Your X/Twitter feed, your rules! Hide/replace tweets with keywords or patterns. Track repeat offenders so you can mute/block them. Features toggle badge & import/export.

Take granular control over your X (formerly Twitter) timeline with ClearFeed for X! This extension lets you define custom rules to automatically filter the content you see.

How it Works: You create rules specifying text to find (using exact phrases or simple patterns) and choose an action: either hide the entire tweet or replace the matched text with something else.

Core Features:

Rule Engine: Match literal phrases or use simple regex patterns (* = wildcard, ? = single char, | = OR).

Control matching with case-sensitive and whole-word options.

Actions:

Hide: Remove the entire tweet from view.

Replace: Substitute matched text with your custom content (supports bold and italic).

Analytics: See a list of twitter handles and tweets which were caught in your rules

Modification Badge: An optional indicator shows which tweets ClearFeed has processed.

Easy Toggle: Click the badge to instantly switch between the original tweet/text and the ClearFeed version ("Un-Hide"/"Re-Hide", "Un-ClearFeed it"/"ClearFeed it").

Rule Management: Intuitive options page to add, edit, enable/disable, and delete rules.

Import/Export: Manage your rule lists easily using JSON import/export.

Privacy: ClearFeed processes everything locally in your browser. Your rules and data stay on your computer. Clean up your feed, avoid spoilers, and create a better X experience. Install ClearFeed for X!
