Filter Manager for Gmail

Tired of manually creating Gmail filters one by one? Filter Manager for Gmail lets you select multiple emails in your inbox, pick an action, and create a filter in one click. Select emails → choose Mark as Read, Archive, Delete, or Label → click Create Filter. Done. The filter is applied to existing emails instantly. When you add new senders later with the same action, they're automatically merged into your existing filter instead of creating duplicates. Switch between filtering by exact email address or by entire domain. Everything runs locally between your browser and Gmail. No external servers, no data collection, no tracking.
