A teacher for the shows you already watch.

Everyone's been told to learn a language by watching TV in it. And almost everyone who tries hits the same wall: you turn on subtitles, you follow the plot, and at the end you've learned the story but barely a word. Watching is not the same as understanding — and a dictionary lookup doesn't close that gap.

StreamTutor exists to close it. It's a Chrome extension that adds an AI tutor to your own Netflix. At the right moments it pauses the show and explains the line out loud — pulling a word apart into its pieces the way a good teacher would — then keeps playing. You can hold the spacebar to ask about any line in your own words and hear the answer back.

The belief behind it

The words you actually keep are the ones whose shape you understood, not the ones you merely translated. Hearing that Fernweh is “far” plus “ache” sticks in a way that “wanderlust” never will. So we built the thing that explains the why, out loud, in the flow of something you already want to watch.

Understanding why a phrase means what it means is what turns a binge into real progress.

Where we are

StreamTutor is a small, independent project in active beta. That means it's genuinely usable today — and also that it's changing quickly, with rough edges we're smoothing as we go. You can follow what's shipping on the changelog.

It works on the Netflix you already pay for, in 30+ languages, and it's free to install. If something breaks or you have an idea, we'd love to hear it — hello@streamtutor.ai.
