Overview

Product summary

Review the store description, core capabilities, and common use cases.

Sign up to not only continue watching the videos you already love watching but learn with some real world examples at the same time.

➤ Supported on Netflix, YouTube, Disney+ (and more coming soon...)

➤ Watch, Review, Recall all in the same platform

We’ll do the flashcard making so you don’t have to! Iago automatically keeps track of the words / grammar you’ve seen and has built custom spaced-repetition quizzes for you to recall the content you’ve seen so far.

➤ The only platform that tracks grammar

We believe grammar is just as important as vocabulary — especially how easy it is to forget part of the structure. Iago tracks and will display grammar on the content you’re watching.

A little finicky, but it seems nice. I hope you can add this extension to KickAssAnime.am soon, since that's my go-to anime website.

I really love it! I'm a Japanese literature major, and this really helps me with my studies, whether it's my Moji, Bunpou, or Choukai. But, if I may ask a request, I would like the anime called Isekai Izakaya Nobu (異世界居酒屋~古都アイテーリアの居酒屋のぶ~) that is on YouTube to have subtitlesTT^TT Thank you very much <3

I usually don't rate apps or extension but this one is truely amazing. After years of studying Japanese without much result, I always wanted to learn through video which I enjoy (other than learning videos). Especially because Japanese is very different from text book one to the day to day language . This extension works perfectly on netflix and is probably the most complete one I've ever seen (and i've been testing plenty of them for ten years.) it even indicates the words by level of difficulty/series you've seen and can be easily found and learn through small quizz To make it really perfect, it would be nice to add the different kanji readings according to the words/meaning because it is regularly missing but a google search does the trick. It would be cool to be able to classify them by type of words (adjective/verb etc)

Its a good app, it show subtitles and you can hoover over them to learn more about the words, if it works. And thats the entire issue. It does not always work, sometimes the lyrics are just in Romanji and it shows no Hiragana/Katakana/Kanji at all and you can also not hoover over words to learn from them. You guys need to bugfix this ASAP!

Currently learning Japanese using this extension. Subtitles are shown pretty clear, and the ability to save words and revisit them later makes this extension great for reviewing learnt words in certain videos.

Netflix in Germany doesn't contain Japanes subtitle option for all of the animes :( Therefore Lago couldn't grab any data and is useless while watching anime :((((((( Only watching Japanese dramas are able to turn on Japnaese subtitle.

I don't normally leave reviews for extensions but this has been such a useful tool so far! If you are learning Japanese and like to immerse yourself with other Japanese media, you definitely need to have this. It's super helpful to expand your vocabulary!

The extension is awesome for watching videos in japanese and also learning. I would maybe appreciate, if there would show hiragana above kanji in the quiz window as well. At least when the question is answered. It would be also great to see option for subtitle in furigana.

This is so helpful! Only recent thing is that for some reason it keeps saying I'm not logged in when on Youtube videos, so I am unable to use it there. When I click on the icon to log in it takes me to my profile which is already logged in. Unsure if I'm missing something but if there's any way anyone might know how to fix this issue it would be greatly appreciated TT
