Language Reactor

What Language Reactor is

Language Reactor turns streaming into study: bilingual subtitles, click-to-define dictionaries and sentence-level playback controls over Netflix and YouTube content.

What you can do with it

• Watch with dual-language subtitles
• Click any word for definition
• Loop and slow tricky sentences
• Save expressions for review
• Train listening on native material

Who it is for

• Language learners past the beginner stage
• Listeners building comprehension
• Teachers assigning native material

What to watch out for

• It works on streaming platforms whose terms restrict modification; extension use carries some account risk, historically tolerated
• Subtitle timing occasionally drifts on some content
• Passive watching is not study; pair with active practice
• Platform changes can break features; check current status
