Tengwar is a language-learning app for Tolkien's Elvish, Star Trek's Klingon and Game of Thrones' Dothraki. Bite-size lessons built only from attested vocabulary, spaced-repetition review, flashcards, an AI tutor that cites its sources, an English-to-Elvish translator and a Tengwar name/script writer. Free to start on the web; Premium removes ads and raises AI limits. Also on iOS and Android.
