asbplayer (Official) by asbplayer

asbplayer is a language-learning assistant, developed for serious language learners who learn their target language through subtitled media.

Unlike similar extensions like Language Reactor, asbplayer is completely free, open source, and compatible with almost every streaming video service that exists.

Using asbplayer, you can enhance any streaming video element with:

• Text-selectable subtitles. You can bring your own subtitle files, or use auto-detected subtitles on popular streaming services like Netflix and YouTube.
• UI and controls to create high-quality Anki flashcards with subtitles, screenshots and audio.
• UI and controls for navigating between subtitles, toggling subtitles on and off, changing the playback rate of the video, and more.
• Special playback modes that e.g. skip all un-subtitled sections of the video in order to optimize your learning.
• Integrates with open source software to annotate subtitles with learning aids - for example, maintaining a database of your known vocabulary to highlight unknown words.

Warning: Unlike the Chromium version, Firefox version of asbplayer does not support recording DRM-protected audio.
