Inspired by https://github.com/davmlaw/they_live_adblocker, Palimpscape is an ad-blocker extension (or a full browser on Android and iOS) that replaces ads with vocabulary, either rare words in your native language if you’re feeling fancy, or more common ones if you are learning a new language.
You can also add your own words that you need to remember.
