Learn Spanish from YouTube videos and Netflix shows

Most Spanish textbooks sound nothing like actual Spanish. The conversations are stilted, the topics are boring, and nothing sticks past next week. If you've ever watched a scene from La Casa de Papel and wanted to understand it without subtitles, that's exactly what Langadoo is built for.

You bring in YouTube videos or Netflix clips, and Langadoo adds dual subtitles, one-click word lookups, and spaced repetition flashcards. Your study material is whatever you already watch.

1. Paste any YouTube URL. Langadoo generates dual subtitles, Spanish and English, synced line by line.
2. Click any word you don't recognize. You see the meaning, conjugation, and an example sentence without leaving the video.
3. Save it. Langadoo schedules it for review at the right interval so you see it again before you forget it.

On Langadoo, every word in your videos and stories is clickable for instant explanations and one-tap saving.

Words like "aprendiendo" and "entiendo" go straight into your spaced repetition deck with one tap, reviewed later at the right interval.

Spanish has over 500 million native speakers and is the most studied foreign language after English. In the US, roughly 40 million people speak it at home. Demand in healthcare, education, and tech keeps growing.

The content never runs out. Netflix keeps expanding its Spanish catalog. Bad Bunny is the most-streamed artist on Spotify globally. There's a steady stream of music, YouTube, podcasts, and drama to learn from, and real reasons to understand it beyond reading a translation.

Paste any public YouTube video and you get dual subtitles, Spanish and English, synced to the audio. It works on vlogs, music videos, football commentary, news clips, or scenes from Money Heist. The vocabulary you pick up is the vocabulary people actually use.

Click any word and you see the meaning, conjugation, and an example sentence in place. Save it and it goes into a spaced repetition deck powered by the SM-2 algorithm, the same scheduling used by Anki. Cards come from scenes you actually watched, so they're easier to remember.

Between sessions, AI-generated reading texts at your level let you encounter saved words in new contexts. This follows comprehensible input theory: you make faster progress when most of what you read is familiar, with just enough new material to push you forward.

The free plan is permanent, not a 7-day trial. You get 20 minutes of YouTube transcription per week, up to 300 saved words, unlimited SRS reviews, and AI word explanations. That's enough to study several scenes from Money Heist or work through a few YouTube vlogs in depth each week.

Paid plans add more transcription time and a larger word limit. But plenty of learners make real progress on the free tier for months before upgrading.

Duolingo gives you cartoon sentences. Anki gives you a blank deck and expects you to fill it. Browser extensions like Language Reactor overlay subtitles on YouTube but don't give you a review system. Langadoo sits between those: you bring in content you already watch, it creates the cards automatically, and reviews them for you. If you've used Anki before, see our comparison of Langadoo and Anki. If you like sentence mining from native content, the tedious parts are handled for you.

Spanish has more content to learn from than almost any other language — music, sport, drama, cooking, news. You don't need a curriculum. You need a way to turn what you already watch into vocabulary that sticks. That's what Langadoo does.
