Watch tonight's episode — without subtitles

TG-lite measures how much of an episode you'll understand and teaches exactly the words that raise that number.

Your English, mapped word by word

A 5-minute adaptive test estimates your CEFR and IELTS level — and builds a living map of every word you know.

Stop studying. Start listening.

Connect your Spotify Premium and get micro-lessons built from the lyrics of the music you already love.

The shortest path to understanding — computed, not guessed

An optimizer picks the smallest set of words with the biggest impact on what you're about to watch or hear.

We remember how you forget

Every answer updates your word map; fading words come back for review.

Your word map appears after a 5-minute placement test.
