Shadow right where you watch.
Loop a line, add a second subtitle track, open the whole script, or upload your own subtitles — on YouTube, Netflix and The Economist.
The browser extension runs only on YouTube, Netflix & The Economist — no screen, mic, or camera recording, no trackers, no ads. It just saves your display settings and reuses your existing login.
Everything you need to shadow, in one place.
Subtitles on the videos you watch
A browser extension auto-loads community subtitles on YouTube, Netflix, and The Economist — and shows the platform's own captions when none exist yet.
Subtitles and notes, shared
Browse subtitles and study notes other learners have polished, and add the ones you like in one click. Export your own notes as .md to use anywhere.
Loop a line, then shadow it
Repeat any line until you can say it, then shadow it in the desktop player and get a 0–100 score for how close your sounds and melody came.
Your language, under every line
The AI translates the whole subtitle track and shows it as a second line under the original — English, Korean, Chinese, Japanese. In the desktop player.
Listen and type it back
Hear a line and type what you caught — graded right, partial, or wrong, with as many takes as you need. Listening practice, sharpened.
Memorize what you watched
Save unknown words from any subtitle as cards and review them on a spaced-repetition schedule — or "mine" a whole sentence into a card with its audio.
Watch it add up
Streaks, plus pronunciation and vocabulary trends, in one dashboard — a reason to come back daily.
Subtitles in many languages
Study subtitles in English, Japanese, Korean and more — SRT and VTT both work. (Pronunciation feedback is English, for now.)
Study alone — with a tutor beside you
In the desktop player. Explanations and chat are multilingual; pronunciation feedback is English.
An AI tutor lives inside the desktop player. It explains the line you're stuck on, finds your weak spots and turns them into practice, and talks with you out loud.
It finds your weak spots
Recurring pronunciation and phrasing slips become sentences to practice again.
Explain any line
Pick a line for instant translation and explanation — or switch to voice mode and just talk.
Your AI, your way
Private, free offline models on your device — or connect Claude / GPT with your own key.
Shape your own tutor
A guided coach helps you craft a custom system prompt — role, tone, feedback style, challenge level — then save several and switch between them.
Or translate the whole track at once
Translate every line in one run and keep it as a saved track — it survives a subtitle rebuild.
See exactly how close you got
In the desktop player. Pronunciation feedback is English, and scores are a guide — they may not be perfectly accurate.
Say a line and your 'closeness' to the original splits into five scores — pronunciation, intonation, stress, fluency, emphasis — with per-word fixes and your pitch drawn over the native's. Skip key words and a completeness score pulls your closeness down.
Five scores, not one
Pronunciation, intonation, stress, fluency, emphasis — each 0–100, so you see exactly where you're weak.
Your pitch over the native's
Your pitch curve sits next to the reference's for every word — flat spots stand out.
Fixes, word by word
"You paused here," "this word's flatter" — pinpointed for every word.
Find it, shadow it, see how close, share it back.
Find a subtitle
Search the library, or capture one from your browser on a supported video.
Shadow the line
Loop each line in the desktop player and say it until it feels natural.
See how close
Get a 0–100 score, with pronunciation and intonation you can actually see.
Share it back
Add the subtitles you polished to the library, so the next learner starts ahead.

Questions, answered
Is it free?
Browsing and sharing subtitles is free. The desktop player has a free offline mode; the richest cloud pronunciation feedback is a Pro feature.
Which videos work?
The browser extension supports YouTube, Netflix, and The Economist. The desktop player works with videos you already have.
Which languages are supported?
Subtitles come in English, Japanese, Korean and more. Pronunciation and intonation feedback is English for now.
Do I need to install anything?
Browse subtitles right here on the web. Shadowing with feedback happens in the desktop player, and the browser extension adds capture on supported sites.
What is Emergence?
A set of tools for learning languages with real content. On this site (emergelang.com) you share subtitles and study notes; the macOS Shadowing Player is where you practice dictation and shadowing with pronunciation feedback. A browser extension that captures subtitles on supported sites is available for Chrome.
What is shadowing?
Shadowing is repeating native speech out loud almost simultaneously as you listen. Because you imitate stress and intonation wholesale — not just individual sounds — it trains listening and speaking together.
Why does dictation practice work?
Writing down exactly what you hear, word for word, exposes the linking and reduced sounds your ear skips when you only follow the gist. Knowing precisely what you can't hear is where listening progress starts.
Which devices does Shadowing Player run on?
Shadowing Player currently runs on macOS; Windows and Android versions are coming soon. Everything on the web — browsing and sharing subtitles — works in any browser.
How is Pro billed?
Choose between an auto-renewing subscription (7-day free trial, cancel anytime) and a one-time PASS for 1, 3, or 12 months with no auto-renewal. Payments are processed securely by Toss Payments.
Who makes the subtitles? What about copyright?
Learners create and share the subtitles and study notes themselves. Every edit is kept in a public revision history, and we operate a copyright notice-and-takedown process for rights holders.
Can other people see my practice records?
No — practice records like your dictation stats are visible only to you. Learning-data collection happens only with your consent, and you can withdraw it at any time.
Can I use it without an account?
Public subtitles, community posts, and the blog are free to browse without an account. You'll need one to share subtitles, like, comment, or keep practice records.
