• (2025-06-19) Ahmed Nasr: Works perfectly with minimal configuration for Netflix. This is the first I've ever written a review for an extension, thank you so much for making this!
• (2025-06-10) Andrew Wang: I love it, works very well. At some point last week, Youtube isn't able to find the subtitles anymore. When they fix it, I will give it a 5 star review.
• (2025-06-07) Matthew Bonwick: It only works on Netflix for me. Prime crashes if I try to load it (I've tried Chrome and Edge). YouTube never detects subtitles, and the audio cuts out constantly. The settings page, particularly the platform section, doesn't save your selected options. So, it will keep loading and crashing websites even if you've selected the option not to run on Prime or YouTube. The Anki extract tool is clunky and not very useful. It's a cool concept, but the app is far from being ready, and on many platforms, it just straight-up doesn't work.
• (2025-05-30) Dinis R: Thank you FluentAI.
• (2025-05-30) Jonson Roy: Useful Extension. Thanks
• (2025-05-30) John Nelson: Great Extension.
• (2025-05-30) Liya Kharitonova: best one out of all tbh, and i’ve tried pretty much everything. trancy looks clean but doesn’t even work right — super buggy, fake reviews all over. language reactor’s way too bloated, UI’s a mess. too much going on, slows everything down. migaku’s confusing and clunky unless you spend hours setting it up. lingopie’s just curated netflix clips with subtitles — barely any real control or depth. fluentai’s the only one that felt smooth and actually useful for picking stuff up. dual subs, clean vocab saving, no lag. still growing but the team actually listens and support’s solid.
• (2025-03-31) Sepehr Spr: in just a word, GREAT. the UI is beautiful, it works smooth and explains every word very clearly. just love it.❤️
• (2025-03-14) Argy Yan: So far this is the best extension I have ever tried for learning a language when watching my Netflix series or I use it to watch Netflix videos that I struggle to understand when the audio is simply too fast (in english). Also I must admit that the FluentAI Neural Subtitles system on Youtube video is amazing compared to the platform one !! Love that :). In my opinion, this extension is underrated and should be brought up to a broader audience !!
• (2025-03-08) Vladyslav Haman: The most stylish extension I've ever had. Extremely useful, works great.
• (2025-03-03) cenk korkmaz: need to login? instant uninstall. why does an extension need an account to translate subtitles?
• (2025-01-27) Roxane Pajoul: Edit Jan 27 2025: Encountered some issues logging in but Sasha worked on it and it works again! Very happy with this extension! It is FREE (at least from my experience after 2 hours of watching this morning). I have tried other extensions and they require you to pay after 15 min. The translation from Dutch to English is pretty good. There are some literal translations that do not make senses but it is usually one word by itself at the end of a sentence that means "right?" or "isn't it?". Otherwise, most translations are very good and I am learning tons new words :D
• (2024-12-04) Jonathan Schoreels: Really bad, tokenizing each subtitle takes more time than the time for the video to go to next one, dictionnary and adding to notebook require multiple click, can't shift-hover with yomitan, the anki export export very basic and non configurable cards.
• (2024-12-01) Mariam Elawady: Extension is stuck at the 'initializing - checking for maintenance' step on YouTube.
• (2024-11-24) öz: fine
• (2024-11-12) Lei Deng: too many bugs, takes forever to load up the subtitles.
• (2024-10-04) Sergey Maksin: Application certainly has potential. I didn't use it much, but give 5 stars after first tests to support and motivate developer to move forward. I decided to get annual subscription to explore this App more. It's already helpful (especially with option to export memory cards to Anki), but as a learner of German I'd be really happy to see in pop-up info some words attributes for Nouns (Der, Die, Das / Plural) and Verbs (Verb tenses forms). Export of words to memory cards in context - great idea. I will try more to see how it works with different levels of language and update review later. But so far - worth checking and already usable and usefull.
• (2024-09-29) WeissP 765: This could be a very nice extension in the future. I had a really good experience with Netflix. However, I ran into some problems on YouTube. It keeps saying that subtitles can’t be found, even when there are non-auto-generated subtitles available. I was super excited when I saw the button "export to Anki", however, the exported CSV only includes original text, no translations, no sources or anything else. Even with these issues, I'm still planning to use this on Netflix. I'm really looking forward to seeing how this extension develops!
• (2024-09-15) Adir Yaakov: I’ve been using this extension for a while now, and it’s amazing how much my language skills have improved just by watching videos. It feels effortless and fun, and I love how it fits into my daily routine. The autodubbing feature in particular is very useful for me.
• (2024-08-19) Andriy Shell: At first glance seems very convenient and powerful tool. Thank you.
• (2024-08-09) Ёжик Angella: Learn and enjoy! What could be better! With this extension, I can not only learn new words while watching my favorite movies, but I can also save them in a notebook for later review. This means my learning continues even after the movie ends! The words I learn come from real-life situations and context, which is incredibly important for effective learning. The double subtitles feature is fantastic for language acquisition, and it also allows me to enjoy movies with my foreign friends. The developers are incredibly friendly and make using this extension a breeze. They are open to suggestions and address any bugs quickly. Highly recommend giving it a try!
• (2024-07-26) Zlata: Extremely useful extension for those who study languages! With its help, the study will be even more interesting and useful. Very comfortable and user-friendly UI.
• (2024-07-16) Ivan: Amazing extension! Works really well on Netflix. It pauses after each sentence and repeats it in a clear computer voice.
• (2024-07-05) RS: A good application for learning a foreign language. I'm learning Finnish.This is the best app I've tried.
• (2024-06-26) Sana M: This is such a cool use of AI! I hope they can support Hulu as well :)
• (2024-06-22) Kantulaev: Excellent alternative to language reactor wish all the best
• (2024-05-23) Mark Sisley: Update: Fantastic developer had this fixed in just a few hours :-) Look forward to seeing how your extension evolves over time! Love the direction of the extension, but I am experiencing a bug where when opening a show, initialization seems to fail, the page refreshes, shows the netflix logo, and the process repeats itself over and over again. Once the kinks are worked out, this will be a fantastic learning aid, much better than other alternatives :-)
• (2024-02-16) Iver Vassilyev: Thank you for your response. I was looking for an alternative to language reactor because it sucks as it blocks YouTube videos. When I discovered yazyk I thought I finally found it but it didn't support youtube, so I'm hoping if you can add it on YouTube even if the captions aren't perfect, as it is my primary use. Thank you.
• (2024-01-24) Mathios Hanani: Amazing app, very useful for learning efficiently ! Great work
