Netflix Dual Subtitles

Dual subtitles on Netflix: show two languages at once, search & jump to lines, click or drag to copy words/phrases, export SRT/ASS.

Watch Netflix with two subtitle languages on screen at once — ideal for language learning, or for watching with someone who prefers a different language. DOES THIS SOUND LIKE YOU? • Want two subtitle languages on screen at the same time? That's the whole point — pick a primary and a secondary and they stay in sync. • Wish you could jump back to the line you just missed — one subtitle at a time, not Netflix's clumsy 10-second skip? Tap a key to step to the previous line, replay it, or go to the next. • Want to train your ear first and only then see the text? "Listen first" keeps a line hidden until you've heard it, then reveals it as the answer — and you choose when it appears: before the line ends, when it pauses, or on hover (pick any mix). • Tired of subtitles covering on-screen text or signs? They follow Netflix's own positioning and move to the top when a line is meant to be there. • Want to drill a tricky phrase — loop it, auto-pause to repeat it, or click a word to copy and look it up? All built in. • Heard a word or phrase and want to see how it's used? Search a subtitle track for it and jump straight to every line it appears in. • Need it easier to read — bigger text, a dyslexia-friendly font, a heavier outline or a background panel? All adjustable. • Want the subtitles as files? Export a single language (.srt), a merged file, or a dual-language .ass that keeps each language's exact timing. WHY IT'S DIFFERENT • Free, with no ads — no paid subscription, no in-app purchases, and the extension never shows you ads or sponsored content. • Uses Netflix's own subtitle data — not machine translation or scraping — so the text and timing are accurate and match what Netflix actually ships. • Runs entirely on your device. No account login, no servers, no tracking; your settings stay in your browser. • Re-watch the exact line you missed — jump back (or forward) one subtitle at a time, instead of Netflix's blunt 10-second skip. Handy for everyone, not just learners. • Tested and looked after — the core behaviour (dual subtitles, language picking, looping, playback speed, the on/off switch) is backed by an automated test suite, including end-to-end tests that drive a real browser, so updates are far less likely to break what already works. • Built-in feedback button — ideas, feedback, and bug reports are all welcome, one click from the popup. ABOUT TRANSLATION Both languages you see are Netflix's own official subtitles — written by professionals for that exact title — not machine translation. Auto-translation is fast but often inaccurate, awkward, or subtly wrong, which is the opposite of what you want when you're learning a language. The honest trade-off: you can only pair languages Netflix actually provides for a given title. If there's enough interest in covering languages Netflix doesn't offer, we may add a higher-quality translation option later — the good ones usually come at a cost, so we'd rather do it properly than bolt on something cheap and inaccurate. FEATURES • Dual subtitles — show a primary and a secondary language together, kept perfectly in sync with the video. The secondary even defaults to the show's original spoken language. Works on the watch player and in the title/preview pages. • Every text subtitle Netflix offers — including languages that aren't preloaded; they're fetched automatically when you pick them. • Transcript viewer — read the whole episode's subtitles, in two views: "Paired" (each line with its translation) or "Timeline" (both languages in time order). The line playing now is highlighted and the list follows along (toggle off to browse freely); click any line to jump the video there. Keep it in the panel, pop it out into a floating always-on-top window, or dock it beside the video (left or right, drag to resize) so the picture shrinks and nothing overlaps. • Skip by line, not by 10 seconds — tap a key to jump to the start of the previous subtitle (, ), replay the current one (.), or skip to the next (/). The second subtitle gets its own keys (J K L), so you can step by either language. Missed what someone said? Hop back to exactly where the line started instead of fumbling Netflix’s 10-second rewind. Works for everyone, not just learners. • Follows Netflix's own subtitle positioning — when a line is authored to appear at the top of the screen (so it doesn't cover on-screen text or signs), it shows at the top too, instead of always pinning subtitles to the bottom like many tools do. • Language-learning controls — loop a line (or a few lines) on repeat with the [ and ] keys (with an optional pause between repeats), auto-pause at the end of each line to read or repeat aloud (and optionally auto-resume after a few seconds), and "Listen first" to hide a line until you've heard it. Loop and auto-pause now work together — pause on every line inside a loop to drill it lap after lap — and you choose exactly when "Listen first" reveals the answer (before the line ends, on a pause, and/or on hover). One-click "Learning", "Listening practice" and "Casual co-watch" modes set these up for you. • In-player control panel — toggle and configure everything from a small N² button right inside the video, so it also works in fullscreen (where the toolbar popup can't open). Drag the button anywhere you like; it shows the title that's currently playing, and scrolls when there's a lot to fit. • Search & jump — search a subtitle track for any word or phrase and click a result to jump straight to that moment. • Click or drag to copy — optionally click a word, or drag-select a phrase, in the on-screen subtitles to copy it to your clipboard (great for looking words up). Off by default. • Export subtitles — download a single language (.srt), a merged file, or a dual-language .ass that preserves each language's exact timing. Episode files are named with the show, season, and episode title. • Customizable & readable — per-language text color, separately adjustable primary and secondary font sizes, adjustable on-screen height, a choice of fonts (including a bundled dyslexia-friendly typeface, or any font installed on your device), and three mixable legibility layers — an outline, a text background that hugs the text, and a window box behind the whole caption area — each with its own colour and opacity. • Playback speed beyond Netflix's range — set anything from 0.25× up to 4× from the panel/popup or with the Shift+< / Shift+> keys, and the extra speeds are added right into Netflix's own speed menu too (kept in sync). Best-effort inside Netflix's menu; the panel and keys always work. • One-tap off switch — a master on/off toggle at the top of the toolbar popup makes the whole extension dormant so Netflix looks and behaves exactly as normal; flip it back on anytime. • Interface in 32 languages — the extension's own menus, tooltips and messages (in the popup and the in-player panel) follow your chosen interface language, defaulting to your browser's. This is separate from the subtitle/video languages, and you can change it anytime; right-to-left languages (Arabic, Hebrew) display mirrored. PRIVACY Runs locally and collects nothing automatically — no analytics, tracking, or ads. A small counter of how many days you've used it stays on your device (to time a one-time feedback prompt) and is never sent. The only data that ever leaves your device is what you type into the optional feedback form, or the short optional feedback page shown if you uninstall — both via Web3Forms, and only when you press send. See the privacy policy for details.

It's a one-person project, made and maintained in my spare time — and made with care: the core features are covered by automated tests (including end-to-end tests in a real browser) so updates don't quietly break things. But one person can't catch everything. If something breaks, or a feature behaves in a way that feels wrong to you, please tell me with the feedback button — I read every message and will look into it. Let's make it a better extension together. SUPPORT Free and ad-free. If it helps your learning or watching, you can support development here: https://ko-fi.com/n2dualsubtitles NOTE Unofficial extension, not affiliated with or endorsed by Netflix. Because it builds on how Netflix's player works, a Netflix change may occasionally require an update — the popup shows a status line so you can tell when something needs attention.
