Short answer: pick by where you watch, not by feature list. Most of these tools only work in one place, so the player you already use decides most of it.
We make BingeLingo, so read this with that in mind. The other tools are products of their own developers, and none of them is affiliated with BingeLingo or Stremio. Features and prices change, so check each one's site for current details.
Start with where you watch
| Where you watch | Look at |
|---|---|
| Netflix or YouTube in a desktop browser | Language Reactor, Migaku, Trancy |
| You'd like shows chosen for learners | Lingopie |
| Stremio in a desktop browser | SubText, or any Stremio add-on |
| Stremio on a TV, phone or tablet | A Stremio add-on: Strelingo, MultiSub, BingeLingo |
Browser extensions can't reach a TV app. That one limit rules out more options than anything else on this page.

On cost: Language Reactor, Trancy, the free Stremio add-ons and BingeLingo all have a free option (BingeLingo's is 5 learning titles, with Dual unlimited). Lingopie and Migaku offer a free trial, then a subscription.
Then ask how you like to study
Once the player has narrowed the list, the remaining choice is about style.
Active, while watching. You pause, click words, replay lines and save sentences. Language Reactor, Migaku and Trancy are built for this. You get the most control, and it suits intermediate learners who already follow most of each line. The cost is that an episode takes longer and feels more like study.
Passive, then tested. You watch straight through and review afterwards. This is BingeLingo's approach: a few words per ten minutes appear in the subtitle line, then a recap quiz and a daily review bring them back. You get less control, but nothing interrupts the show.
Just two lines. You want both languages on screen and nothing else. Any dual-subtitle tool does this. It helps you follow along, though the research on dual subtitles is cautious about how much you retain without some kind of review.
Neither active nor passive is better. The one that works is the one you'll still be doing in three months.
A note for beginners
Most of these tools assume you can already read a subtitle in the language you're learning. If you can't yet, dual subtitles turn into reading your own language with decoration on top.
Two things help at that stage. One is easier content, which is where a learner-focused catalogue like Lingopie's can be useful. The other is keeping your own language as the base and adding words gradually, which is what BingeLingo's Bridge mode does. More on choosing native or target-language subtitles.
Can you combine them?
Yes, and many people do. A common setup is a browser extension for YouTube on the laptop and a Stremio add-on for films and series on the TV. If you use Anki, it can be the place everything meets: BingeLingo exports its vocabulary as an Anki deck.
Common questions
What is the best Language Reactor alternative?
It depends on where you watch. In a desktop browser, Migaku and Trancy are the closest. In Stremio, you need a subtitle add-on. Here's how Language Reactor and BingeLingo compare.
Which of these work on a smart TV?
Lingopie has smart TV apps. Stremio add-ons run inside the Stremio app, so BingeLingo works on Android TV. Browser extensions don't run on TVs.
Can you learn a language just by watching TV?
Watching gives you exposure, which helps, but words stick when you're tested on them. Whichever tool you choose, pair it with some review. Here's the research.
