Twitter Filter

Twitter Filter lets you hide or flag tweets on your timeline using custom rules.

You write conditions based on tweet content or account properties -- things like follower count, account age, whether a tweet contains links, or if the username matches a pattern. Matched tweets can be hidden entirely or visually dimmed with a label showing which rule triggered.

The rule language supports comparisons, string matching, regex, and basic logic operators. A few preset rules for common cases (crypto spam, suspicious accounts) are included and can be toggled on or off.

Other features:

- Import CSV lists (e.g. from Twitter Exporter) and reference them in rules with in_list()
- Export and import rules as JSON to share with others
- A stats page showing how many tweets were scanned, marked, or hidden, broken down by rule
- Global toggle to enable or disable all filtering
- Default action setting (mark or hide) that individual rules can inherit or override

The extension runs entirely in your browser. No data is sent anywhere.
