The Language Reactor alternative with a teacher built in
Everything you like about Language Reactor — dual subtitles, a click dictionary, your own Netflix — plus an AI tutor that explains the line out loud and answers when you ask.

Where Language Reactor is strong
Language Reactor is free, mature, and excellent as a dictionary layer. If you already know enough grammar to teach yourself, it does the job and costs nothing.
Where StreamTutor pulls ahead
StreamTutor adds the part a dictionary can't: a spoken teacher. It breaks a word into its pieces out loud, and you can hold the spacebar to ask about any line and get a voice answer — the thing that closes the gap when you can read a subtitle but can't feel why it's built that way.

Language Reactor alternative: common questions
Yes. It does the same core things — dual subtitles, a click dictionary, and learning from your own Netflix — and adds a spoken AI teacher that explains lines out loud and answers questions you ask by voice.
Language Reactor is a dictionary layer: it tells you what a word means. StreamTutor is a teacher: it tells you why, out loud, and you can ask follow-up questions about any line.
You can, though they overlap. Most people pick one. If you want spoken explanations and a tutor you can talk to, StreamTutor is the one to run.
