Does Language Reactor Work on Amazon Prime or Any Website?

No. Language Reactor does not work on all platforms. It is a browser extension, so it works only where browser playback and extension injection are supported.

Common limitations

• Local MKV and MP4 support is limited compared with desktop tools
• Support varies by streaming platform and updates
• Browser and extension conflicts can break workflows
• Offline study is limited compared with desktop tools

If your workflow includes downloaded videos or mixed sources, desktop-first tools are more reliable.

For the broader switch decision (not just platform support), read desktop alternative to Language Reactor.
