Language Reactor is one of the best-known tools for learning languages with TV. It's a browser extension that adds dual subtitles, a pop-up dictionary and word saving to streaming sites, mainly Netflix and YouTube. If that's where you watch, it's a good choice.
But it's built for those sites in a desktop browser. It doesn't work inside the Stremio app, on Android TV, or with the other sources Stremio can play. If Stremio is your player, you need something that works in Stremio.
This page covers what BingeLingo does, how it differs from Language Reactor, and when each one is the better fit.
Language Reactor is a product of its own developers; BingeLingo is not affiliated with it, or with Stremio. Their features and prices change, so check their site for the current details.
The core difference
Language Reactor adds tools around the video: a transcript beside the player, clickable words, playback controls. You learn by interacting: pausing, hovering, looking up.
BingeLingo changes the subtitles themselves and moves the studying to after the episode. You watch normally, with no clicking. New words are woven into the subtitle line, and a recap quiz and spaced review happen once the credits roll.
Neither approach is objectively better. They suit different ways of watching.

Choose Language Reactor if…
- You mostly watch Netflix or YouTube on a laptop.
- You like to study actively while watching: pausing on every line, clicking words, replaying sentences.
- You want a full transcript next to the video.
Choose BingeLingo if…
- You watch in Stremio, especially on a TV or Android device, where browser extensions can't reach.
- You want to watch without stopping and do the learning afterwards.
- You're a beginner: Bridge mode keeps your own language as the base, so you can follow a full episode from day one instead of drowning in target-language subtitles.
- You want the review done for you: the quiz and the spaced schedule happen automatically, with no deck to build.
Why "no clicking" can be a feature
Click-to-translate tools are powerful, but every lookup interrupts the scene, and it's easy to end up reading a dictionary instead of watching a show. BingeLingo's bet is different: pick a few genuinely useful words per ten minutes, put the translation right in the line, and test you on them afterwards, when testing works best.
That split between encoding (watching) and retrieval (the quiz) comes from well-established memory research: testing yourself beats re-exposure for long-term retention (Roediger & Karpicke, 2006). The full write-up is here.
Can you use both?
Yes. Plenty of people use Language Reactor for YouTube clips and Netflix on their laptop, and Stremio with BingeLingo for evening TV. Your BingeLingo vocabulary exports to Anki, so if Anki is your central deck, it can hold words from everything you watch.
