Subtitles with dictionary on Netflix (plus dual)

So, last night I got interested in Migaku and Kitsun, but quickly found the limitations when it comes to watching shows with subtitles with them.

Here are my first impressions:


  • They say they support Netflix, Disney+, etc through a browser extension for Chrome.
  • They have a legacy and a current version, the current one is in development and doesn’t have the features of the legacy.
  • Reviews place both at roughly 3 out 5, most of them complaining it’s not working or buggy. (And looking at reddit most threads complain about both not working.) So I didn’t try.
  • You can use a dictionary and create Anki cards with it.
  • Pros: Works with streaming.
  • Cons: Does it really work? Quality is under dispute. Costs money.


  • Kitsun follows the approach of using one of your local video files.
  • You then add one or two .srt subtitle files to it.
  • While this seems more stable, I don’t actually own any anime video files, I usually stream.
  • You can use a dictionary and create cards in their in-website SRS system.
  • Pros: Seems to work.
  • Cons: You need your own video files. Costs money.

Ironically, with a bit of research, it wasn’t too hard to recreate the experience myself for free thanks to the hard work some people shared on the internet. (At least for Netflix.)

I needed three browser extensions:

  • Yomitan: Since Yomichan has been abandoned, Yomitan is the fork of the project that seems to work quite well. Allows marking text and quickly displays a dictionary page for it.
  • Subadub: Here. Allows subtitles to be mouse-clickable. I installed it and Ctrl+F5 my Netflix stream and I was able to select text. And Yomitan worked immediately.
  • NflxMultiSubs 2021: Here Allows displaying two subtitles at once. Allows loading .srt files.

The good news is that all of these play together:

  • The subtitle extension adds a little toolbar at the top, and the subtitles you select there are considered the primary ones by Subadub.
  • The subtitles you select from your Netflix menu become the secondary ones if you want them.
  • You can click, select, and copy your primary subtitles, and hence also use Yomitan on them.

Here is an example of what it looks like for me:

This is Japanese [CC] selected in the browser extension and English in the Netflix subtitles. I have selected some section with Yomitan. That’s what I wanted!

A word of caution, though. When Subadub is active, it can, due to its bigger font, obscure the secondary subtitles from the other extension, especially if you hover your mouse and the scroll bar comes up. Online I found you might be able to move subtitles in Netflix, but when I looked at the subtitle settings, this does no longer seem to exist.

However, if you select “Hide Subs” from the toolbar, this happens:

Yes, dual, readable subtitles. So when you need dictionary support, just click “Show Subs” and do what you need to do.

I didn’t try loading my own subtitle .srt file but I think that should work fine, too. This might be needed if you want Japanese subtitles for shows that don’t have them.

Oh, and you can slow down the playback speed on Netflix, too, giving me a chance to actually match up what is said with the text.

Hope this helps someone else, too. :slightly_smiling_face: It costs nothing to try and should be okay to do.

Disclaimer: I’m not affiliated with any of these extensions. I just made use of them.


To clarify further:

What you see on the top right is the toolbar added by Subadub. Hence when you click “Hide Subs” it removes the over-emphasized, clickable, selectable subtitles but leaves Netflix original subtitle display intact.

What you see covering most of the screen is the expanded subtitle dialog you get when the other extension is active. As long as you select Japanese as your primary subtitles, you can use it with Subadub+Yomitan.

If you click on the dual subtitles extension, you can quite handily configure the display:

(Sorry for image quality, I’m taking photos of my screen with my mobile.)

What you get with Subadub hiding subtitles:

What you get when you show subs to be clickable (this changes depending on the layout chosen in the dialog above):
