Ask about any line
StreamTutor pauses, explains the line out loud in your language, then keeps playing.
A teacher in your ear — with all the context
Hear what the line means, why it's said that way, and when you'd use it yourself — in your language.
Beyond literal meaning
The real meaning behind every line.
Tone & intent
Pick up sarcasm, irony, and nuance.
Cultural context
Understand the moment, not just the words.
Slang & natural usage
How native speakers actually say it.
Watch normally. Learn when you need it.
Ask when a line stops you, get occasional explanations, or turn on practice mode when you want to drill. StreamTutor adapts to the way you want to watch tonight.

Sylvia... who are you?

QWhy does he say tu parles here?
ATu parles literally means "you talk," but here it's sarcasm, like "Yeah, right" or "Sure." French speakers use it to brush off something they don't buy. A close English match is "Tell me about it," said with an eye-roll.
At 9:11
QWhat does je m'en doutais mean?
AJe m'en doutais means "I suspected as much" or "I had a feeling." Careful: se douter de is a false friend. It isn't "to doubt," it's the opposite, "to suspect." So this is "I figured," not "I doubted it."
At 9:08
QWhere does cambrioleur come from?
ACambrioleur means "burglar," from the verb cambrioler, "to break in." A burglary is un cambriolage. For a thief in general, you'd say un voleur instead.
At 21:03
QWhat does ça marche mean?
AÇa marche literally means "it works," but in conversation it's "okay" or "sounds good," the way you agree to a plan. Someone suggests noon and you reply ça marche. You'll also hear ça roule, a bit more casual.
At 20:48
QWhy du coup everywhere?
ADu coup means "so" or "as a result," but the French sprinkle it in like a filler, closer to "so anyway." In writing you'd use donc instead. In speech it's almost a verbal tic.
A lesson from your own week of watching
Every week, StreamTutor looks back at the lines you asked about and the patterns that kept showing up — then sends you a short teacher note with what to review next.
- Built from your actual questions
- Highlights recurring patterns
- Turns watching into steady progress
Real Dialogue. Real Context. Zero Boring Drills
StreamTutor works across 30+ languages, inside the streaming subscriptions you already have.
QWhat does se cogner à la vie mean?
ASe cogner literally means to bump into something or hit yourself against it. Se cogner à la vie turns that into an image: letting life bruise you a little instead of staying protected. In context, he's telling Amélie she is not made of glass, so she can risk real life.
QWhat does fēng mean here?
AFēng means "wind" (风), but here it's also Jin's persona: free, restless, hard to hold. The pattern xiǎng tíng jiù tíng means "if it wants to stop, it stops." So the line is a playful comeback: even a wandering wind can choose to stop.
QWhat's the feeling behind beso here?
ABeso means "a kiss," from the verb besar (to kiss). In la llama divina de un beso ("the divine flame of a kiss") it's clearly romantic. For something lighter, use un besito, a quick peck, the way friends sign off a message.
QWhat does tatsächlich sehr mean, and where else could I use it?
ATatsächlich means "actually" or "in fact," and it confirms that something really is so. Add sehr ("very") after it and you get "really, very much so." You can use tatsächlich anywhere you want to stress that something is true, as in Das stimmt tatsächlich ("That really is true").
QWhat does 幸せ (shiawase) really mean?
A幸せ (shiawase) means "happiness," the calm, contented kind rather than excitement. It works as both a noun and an adjective, so 幸せです just means "I'm happy." Here これ以上の幸せなんてない means "there's no greater happiness than this."
QWhere does the word ficou come from?
AFicou is the past tense of ficar, which means to stay, to remain, or to become. It comes from Latin fīgere (to fix in place), so the sense of something staying put is built in. Here ficou em mim means "it stayed in me." Brazilians use ficar constantly: it also covers "to be located" and, casually, "to hook up with someone."

Common questions
A Chrome extension that adds an AI language tutor to Netflix. It shows dual subtitles, lets you click any word to save it, and at the right moments pauses the show to explain the line out loud, then keeps playing.
StreamTutor works on Netflix's entire catalogue. Any show or film with subtitles in your target language becomes a lesson — from this week's hit series to classic cinema. 30+ languages are supported, including Spanish, French, German, Japanese, Korean, Mandarin, Italian, Portuguese, and more. The classic films on this page are simply examples we're free to show publicly.
Yes. The teacher isn't only for English speakers. Set your own native language and it explains in that language. A Portuguese speaker learning French, for example, hears the explanations in Portuguese and reads the second subtitle in Portuguese too. Over 30 languages work as your base language, not just as the language you're learning.
No. StreamTutor works on your existing Netflix. There's no separate catalog to pay for, so you learn from the content you already watch.
No. You choose the audio language in Netflix's own menu. StreamTutor handles the subtitles and the spoken explanations. It never changes which audio track plays.
Your Netflix account is safe. StreamTutor runs entirely in your browser as a standard browser extension and doesn't modify or interact with Netflix's servers. It reads the subtitle files your player already loads and adds a teaching layer on top. Netflix's terms permit personal browser extensions that don't redistribute content.
Yes. Every install comes with a 7-day free trial — full Pro access. You'll add a card to start, but cancel anytime before day 7 and you won't be charged. After the trial it's $19/month.
We store the words and lessons you save so you can review them. We don't sell your data. Full details at streamtutor.ai/privacy.
