Twitter Filter

Twitter Filter lets you clean up your Twitter/X timeline using custom rules. Write conditions based on tweet content or account properties — follower count, account age, bio keywords, username patterns, verification status, and more. Matched tweets can be marked with a yellow border, hidden entirely, or trigger an automatic block (with delay and undo). The rule language supports comparisons, string matching, regex, and logical operators. Subscribe to rules: Browse and subscribe to rules published by other users. Subscribed rules sync automatically, so you always have the latest version without manual updates. Create and share your own: Write custom rules with the expression language, then publish them for others to subscribe to. Other features: - Import screen name lists from CSV or paste directly — each rule supports up to 100,000 names - Export and import rules as JSON - Stats showing how many tweets were scanned, marked, hidden, or blocked - Your own tweets and tweets from accounts you follow are always skipped Tweet filtering runs entirely in your browser. Rule sharing is optional and only syncs rule metadata — your timeline data never leaves your device.
