免费 / 开源Parrot is an immersive Spanish learning app that repurposes the short-form video scroll into a language-acquisition engine. Instead of grammar drills and gamified streaks, Parrot feeds you clips of native speakers at roughly your comprehension level, lets you tap any word for an instant translation, and nudges you to say the line back out loud. Saved words feed a personal dictionary that returns through spaced repetition, so what you pick up during a commute actually survives to next week.
