# FlixFluent > FlixFluent is a Chrome extension plus companion web app that turns Netflix and YouTube into a structured language-learning environment: dual subtitles, hover translation, click-to-deconstruct word and sentence analysis, and a "digger" flow where every word inside an explanation is itself clickable for a deeper explanation. The base subtitle line uses the platform's own track in your language when one exists and is AI-translated in context when it does not; auto-generated (ASR) and auto-translated YouTube caption tracks are visibly flagged. Word translations and pronunciation audio are generated in the context of the exact sentence — no dictionary lookups — and cached. The web app adds an FSRS-based vocabulary trainer fed by the words you look up while watching (with Anki / CSV import) and CEFR-mapped proficiency tests for English, Korean, German, French, and Spanish. It costs $17 / month ($159 / year, $399 lifetime) with a 7-day free trial and 30-day money-back guarantee. The strongest cohort is Korean learners; supported deconstruction also includes Japanese, Chinese, Spanish, French, German, and others. Built by Flixfluent Co. Ltd in Seoul, South Korea. ## Core pages - [FlixFluent homepage](https://flixfluent.com/en/): Product overview, features, pricing, install link. - [About FlixFluent](https://flixfluent.com/en/about/): Who FlixFluent is for, how it works, what it costs, and the company behind it. - [FAQ](https://flixfluent.com/en/faq/): Long-form FAQ covering pricing, supported platforms and languages, install steps, privacy, refunds, and comparisons. - [Pricing](https://flixfluent.com/en/#pricing): $17 / month, $159 / year, or $399 lifetime — 7-day free trial, 30-day money-back guarantee. - [Privacy policy](https://flixfluent.com/en/privacy/): What data FlixFluent collects and how it is used. - [Terms of service](https://flixfluent.com/en/terms/): Subscription, refund, and acceptable-use terms. ## Product features - [Dual Subtitles for Netflix & YouTube](https://flixfluent.com/en/dual-subtitles/): Dual (bilingual) subtitles for Netflix and YouTube: FlixFluent uses the platform's own subtitle track in your language when it exists, AI-translates when it doesn't, and flags auto-generated YouTube captions.
