Chrome extension · Interface in 12 languages · 14-day full free trial · Cancel anytime
Lexisub is a Chrome extension that shows two or more subtitles at the same time on Netflix — for example, the language you're learning above one you already read — synced to Netflix's official subtitle tracks. Save any line with one key, review your saved phrases in study mode with segment loops, and export them to Anki. It's built for language learners, especially Gen Z viewers who learn while they stream.

Your native language and the one you're learning, overlaid on the Netflix player and perfectly synced. Click any word to save the whole line for later.

Study scenarios with dual subtitles — from your first episode to fluent, in the language you're already watching.
Made for Gen Z
For a lot of Gen Z learners there is no separate "study time" — the language comes from the K-dramas, anime and international series they already watch. Lexisub is built around that habit: no textbook, no streak to protect, just tonight's episode with two languages on screen.
Nothing extra to schedule. Put the language you're learning above one you already read and keep watching — the meaning lands in the same second as the line.
Slang, jokes, interruptions and fast comebacks — the real speech textbooks skip, straight from the shows everyone is talking about.
One key saves the whole line with its scene. Pro syncs your phrases to every device and exports them to Anki, Markdown or PDF.
Not just multiple subtitles — a study tool wrapped around the shows you already watch.
Show multiple languages at once on Netflix, using official subtitle tracks or your own .srt / .vtt files.
Subtitles track playback frame-by-frame. Nudge timing if a file is off — no buffering, no re-encoding.
Click a word or hit a shortcut to save the whole line in every language. Sign in and your phrases sync to the cloud — reach them on any device. Export to CSV (Anki), Markdown, or PDF.
Loop any saved segment to shadow and repeat. Your phrase cards on one side, the player on the other.
No track in your language? Generate one with your own DeepL, OpenAI, or Google Translate API key.
Your saved phrases stay on your device. No ads, no trackers, no selling your data.

Loop any saved segment to shadow and repeat. Your phrase cards on one side, the player on the other.

Lexisub is a Chrome extension for language learners that shows two or more subtitles at once on Netflix, synced to the official subtitle tracks. You can save any line with one key, review saved phrases in study mode, and export them to Anki.
Language learners who would rather study with real shows than with drills — especially Gen Z viewers who already watch K-dramas, anime and international series and want to pick up the language along the way. Beginners use the second line to follow native content; intermediate learners use it as listening practice with a safety net.
Every new install gets a 14-day free trial with every feature and no card required. After the trial you can keep using one subtitle line for free. Pro adds unlimited subtitle lines, phrase review, study mode, exports and cloud sync for €24.99 per year (about €2.08 per month) or €2.49 per month at the current launch price.
Netflix is fully supported in Google Chrome. Prime Video, Disney+ and Max are available in beta, using the subtitles already shown on screen. You can also load your own .srt or .vtt subtitle files.
Lexisub reads Netflix's official subtitle tracks, so timing stays in sync. It can show more than two languages at once, saves a whole line with one key press, and includes a study mode with segment loops and Anki export. AI subtitles use your own translation key, so you pay the provider directly with no markup.

The interface is available in 12 languages — English, Korean, Chinese, Japanese, Hindi, Spanish, French, Arabic, Bengali, Portuguese, Russian, and Indonesian — switchable instantly from the popup. For subtitles themselves, you can pair any of the official languages a Netflix title carries, load your own .srt/.vtt files, or generate a missing track with your own translation key.
Only for AI translation of languages Netflix doesn't provide. Multiple subtitles from official tracks or your own files work without any key.
