LinkedIn's job search keeps showing you postings you've already seen, applied to, or don't want. ApplyW adds the filters it's missing: hide any listing, block a company outright, hide anything already marked Applied or Viewed, and filter by keywords or by the language the description is actually written in.
A metrics page shows which of your filters is doing the most work. Everything runs locally in your browser - no account, no server, nothing sent anywhere. Free and open source.
