Migaku

Migaku is a browser extension for learning Vietnamese through the videos, websites, and subtitles you already use. It fits learners who like immersion and want help understanding real content as they go, especially if you enjoy picking up vocabulary from YouTube, streaming video, and articles instead of following a traditional lesson path.

The main appeal is the click-to-lookup workflow. You can tap words in subtitles or web pages to see definitions, pronunciation, images, and AI explanations in context. From there, Migaku can turn what you just watched or read into flashcards with the sentence, meaning, audio, and often a screenshot, so review feels tied to something real rather than a random word list.

It also tracks what you know and gives content a rough comprehension score, which helps you choose material that is challenging but not impossible. That is useful if you want a tool that supports both reading and listening practice. You can learn more on Migaku's site and see the extension on the Chrome Web Store.

The tradeoff is that Migaku is more of a study system than a simple dictionary add-on. You get the most value if you already like learning from native content and want to build your own cards consistently. It is less ideal if you want a clear, self-contained Vietnamese course inside the extension or regular speaking practice with real people.
