Hi @Metlos,
I saved this screenshot before I subscribed to Pro in Juneish (2023):
In the most recent News from the Team (News from the Team), the Developer David_Wilkinson mentions Speech Recognition on Netflix (“Subs for Dubs”) also being a part of the Pro features soon.
Some Details from the Help Tab -> FAQ Tab of Language Reactor
What does the Pro subscription include?
Pro mode primarily includes 2 additional features: machine translations and saving words and phrases. A single Pro subscription can be used on Netflix, Youtube and LanguageReactor.com website (TurtleTV, flashcards, text mode). […] Some quotas apply for machine translations: you can watch about 5 hours of (new, previously untranslated) content every day. This quota also applies to exporting subtitles - machine translations will only be included within the quota.
Note: This note is up-to-date with how things stand as of July 2023. As for how out of date it is, I am not sure.
From what I recall from my Pro Trial period experience, after using Pro to mark and save words, you should still be able to see all your saved words and phrases; you just won’t be able to save anymore or get Machine translations (and now "Speech Recognition on Netflix ‘subs for dubs.’
I hope this helps!
