FlexiLingo – Video & Podcast Learning

Learn languages on YouTube, Spotify & BBC with interactive subtitles, word translations, and CEFR levels.

Features & Capabilities

FlexiLingo transforms everyday media into a language classroom — without leaving YouTube, Spotify, or BBC.

Install it once. Then watch, listen, and read your way to fluency.

Interactive Subtitles Every word in the subtitle is clickable. Tap any word to instantly see its translation, definition, pronunciation, and example sentences — in the middle of the video, without interrupting your flow.

CEFR-Color-Coded Vocabulary Words are automatically color-coded from A1 (beginner) to C2 (advanced), so you always know which words are worth your attention and how your vocabulary is growing.

Phrases, Idioms & Collocations FlexiLingo doesn't just analyze single words — it detects phrasal verbs, idioms, and fixed expressions, so you learn language the way native speakers actually use it.

Save Words & Review with Spaced Repetition Save any word or phrase to your personal deck with one click. Then review it using flashcards and a spaced repetition system that schedules reminders at the perfect moment.

AI-Powered Content Analysis FlexiLingo analyzes the full content of videos and podcasts to surface vocabulary by CEFR level, highlight collocations, detect grammar patterns, and show which words appear most frequently — so you can prioritize smarter.

Works Where You Already Learn YouTube, Spotify, BBC, News in Levels, SpotlightEnglish — no need to change your habits. FlexiLingo works where you already spend time.

Whether you're preparing for IELTS, learning a new language from scratch, or just trying to understand native speakers better, FlexiLingo is the tool that turns passive watching into active learning.
