Built for language learners

Not just multiple subtitles — a study tool wrapped around the shows you already watch.

🎬

Multiple subtitles

Show multiple languages at once on Netflix, using official subtitle tracks or your own .srt / .vtt files.

🎯

Perfectly synced

Subtitles track playback frame-by-frame. Nudge timing if a file is off — no buffering, no re-encoding.

💾

Save & review phrases

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.

🔁

Study mode

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

🌍

Your own AI translation

No track in your language? Generate one with your own DeepL, OpenAI, or Google Translate API key.

🔒

Private by design

Your saved phrases stay on your device. No ads, no trackers, no selling your data.

Frequently asked questions

Is Lexisub affiliated with Netflix?

No. Lexisub is an independent browser extension and is not affiliated with, endorsed by, or sponsored by Netflix or any other streaming service. All trademarks belong to their respective owners.

How am I billed?

Payments are handled by Paddle, our Merchant of Record. Paddle processes your payment, issues your receipt, and handles applicable taxes. We never see or store your card details.

Can I cancel or get a refund?

You get a 14-day free trial to evaluate everything before you pay, so you only subscribe once you know it works for you. You can cancel anytime and keep Pro until the end of your paid period; we don't pro-rate unused time. Paid periods are non-refundable except where required by law or granted at our discretion. See our Terms for details.

What languages does Lexisub support?

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.

Do I need an API key?

Only for AI translation of languages Netflix doesn't provide. Multiple subtitles from official tracks or your own files work without any key.

What data do you collect?

An email address to link your subscription, and that's it on our servers. Your saved phrases and settings live in your own browser. See our Privacy Policy for details.
