FluentAI is a very helpful tool for learning languages while watching movies and series. I use it on Netflix, Disney+ and YouTube, and it works well.

You can see subtitles in two languages at the same time, which makes it easier to learn new words. You can set the video to pause after each phrase to read its translation in your native language.

There is also a feature that lets you click on a word to see its meaning and hear how it sounds, and also to explain it. The design is simple and easy to use. Some features are paid. It’s a great extension for language learners. I recommend it.
