Learn French from Netflix & YouTube — Click Any Word to Translate
DeepLingo's Chrome extension turns every French video into a vocabulary lesson. Click a word on the subtitle, get an instant translation with IPA and examples, and save it to your DeepLingo vocabulary for spaced-repetition practice.
Free version always free. Premium features free for everyone until May 31 — then included with any DeepLingo subscription, or $9.99 CAD/month ($49.99/year) standalone.
What you get
Built specifically for French learners preparing for TCF or TEF Canada — and anyone who learns vocabulary best in context.
Works on Netflix & YouTube
Native captions are replaced with clickable ones. Click any French word for an instant translation popup with IPA, examples, and grammar notes.
Saves to your DeepLingo vocabulary
Saved words sync to your DeepLingo account with show title, timestamp, and source URL — ready for spaced-repetition practice on the web app.
Saved-word fade
Words you already know fade out in the on-video overlay, so new vocabulary visually pops out — no manual highlighting.
Transcript sidebar
Press T to open a searchable transcript of everything spoken in the video. Click any line on YouTube to seek to that moment.
Dictionary + Chrome translator fallback
Bundled French dictionary covers most words. Anything missing routes through Chrome's on-device translator (Chrome 138+) — fast, private, no API key.
Private by default
Telemetry and crash reports are opt-in and off by default. We never collect subtitle text, video URLs, or anything you click.
How it works
Three steps from install to your first saved word.
Install from the Chrome Web Store
One-click install. Works on Chrome, Brave, Edge, and other Chromium browsers.
Sign in to DeepLingo (optional during promo)
Sign in to sync saved words with your DeepLingo account. During the free promo (until May 31) you don't need an account at all.
Open a French video
Go to any French YouTube or Netflix video, enable French captions, and start clicking words. Translations appear instantly — no typing.

Comparison accurate as of May 2026, based on publicly available information from each provider's official website or Chrome Web Store listing. Features and prices can change — we review this table quarterly. Each tool solves a slightly different problem: Language Reactor and DeepLingo focus on learning from streaming video, Toucan teaches vocabulary while you browse, and Grammarly checks the grammar of text you write.

Who it's for
TCF / TEF Canada candidates
Build vocabulary in context from real French media — the same vocabulary the listening and reading sections of TCF and TEF draw from. Saved words flow into your DeepLingo practice queue.
French immersion learners
Watch what you'd watch anyway. The extension turns Netflix and YouTube into a vocabulary feed — fade out what you know, expose what you don't.
Express Entry & Francophone Mobility applicants
Reach CLB 5 (B1) for Francophone Mobility or CLB 7 (B2) for the 50-point French CRS bonus. Vocabulary breadth is the single biggest predictor of TCF/TEF reading and listening scores.
