How it works

  1. 1

    Press play

    Add the browser extension and watch what you already watch — YouTube videos, streaming shows — with subtitles in the language you are learning.

  2. 2

    Click what you don’t know

    Click any word or phrase in the subtitles to get an instant, AI-generated explanation of what it means right there, in context. Save it in one click.

  3. 3

    Practice until it sticks

    Flicktionary schedules reviews of your saved words with spaced repetition, so the vocabulary from your shows actually ends up in your long-term memory.

Every word you save, in one place

Each lookup you keep lands in your vocabulary, with its translation and the subtitle line it came from. Filter by language, search your terms, and see at a glance what is due for review.

Spaced repetition does the scheduling

Flicktionary tracks what you know and resurfaces each word right before you would forget it. Review in reading mode or with flashcards, and promote the words you want to use — not just recognize — to your active vocabulary.

Ask the AI tutor anything

Wondering how a word differs from its synonym, or why a sentence uses that form? Every saved term comes with an AI tutor that answers questions about meaning, nuance, grammar, and usage.
