Steps
Install the Language Reactor extension from the Chrome Web Store in Chrome or Edge. Pin it to your toolbar so you can switch it on and off quickly.
Create a free Language Reactor account and sign in. Set your native language and the language you are learning in the settings panel.
Open Netflix or YouTube and play a show in your target language. Turn on Language Reactor so two subtitle lines appear, one in each language.
Use the subtitle panel to read along while you listen. Keep the original audio on and avoid your native dub so your ear trains on real speech.
Hover over any word in the subtitles to see its meaning and save it to your word list with one click. Save only words you meet again and again.
Open the saved words page and review your list. Mark words as known once you recognise them without help, and export the rest to Anki if you use it.
Slow the playback speed to 0.75x when a scene is too fast, then return to normal speed. Replay short segments until you catch every word.
Aim for one short episode or a 10 to 15 minute clip a day. Consistency beats long weekend sessions for building listening comprehension.
Tips and common mistakes
Do not save every unknown word. Focus on high frequency words that keep appearing in your shows.
Watch with target language subtitles first, then rewatch the same scene with subtitles off to test your listening.
Pick shows you already know the plot of so you can guess meaning from context instead of pausing constantly.
