Parrot vs Experiment Helper

LEARN SPANISH BY WATCHING REAL SHORT VIDEOS Parrot teaches you Spanish the way you actually pick up a language: by watching real people speak it. Scroll a feed of short videos from native speakers, tap any word or phrase in the captions to see what it means, save it, then practice it until it sticks. No textbook Spanish – the vocabulary, pronunciation and slang people really use. Starting from zero, or studied for years and still freeze in a real conversation? Parrot meets you at your level and builds from there. HOW PARROT WORKS ► Scroll real videos – Short, authentic clips from native speakers, matched to your level. ► Tap to translate – Tap any word or phrase in the captions for an instant translation, then save it to your personal dictionary. ► Practice what you just watched – Quick activities after every video: match the words, fill in the blank, build the sentence, and say it out loud with instant feedback on your pronunciation. ► Review with flashcards – Your saved words and phrases come back until you know them. ► Follow your own path – A personalized learning path that adapts as your vocabulary and listening comprehension grow. ► Build the habit – Streaks, badges and challenges keep you going a few minutes at a time. You can even import your streak from other apps. ► Every milestone plants a tree. WHICH LEVEL IS PARROT FOR? ► Complete beginners – Start with beginner videos and the most common words and phrases, and understand real Spanish from your first week. ► Intermediate learners – Break through the plateau with real speed, real accents and real conversations: the listening and speaking practice that drills can't give you. ► Returning learners – Took Spanish in school? Rebuild it fast by immersing yourself in the language every day. WHO USES PARROT ► Travellers who want to actually talk to people on their next trip. ► Busy adults and parents who have ten minutes, not an hour. ► Students who want Spanish to make sense outside the classroom. ► Movie and music lovers who want to understand Spanish TV shows, series and songs without subtitles. WHAT LEARNERS SAY ► Christine, US: “I love how Parrot makes learning effortless. Just watching videos has improved my Spanish so much!” ► Stephani, Canada: “With Parrot, I stopped speaking textbook Spanish. Now I understand real conversations and feel confident speaking Spanish!” ► Marcus, UK: “I can scroll for 10 minutes and feel like I actually learned something.” SUBSCRIPTION INFORMATION Parrot offers auto-renewing Parrot+ subscriptions that unlock all videos, activities and features.
