Saved from Netflix

Sound familiar?

Years of lessons. Still lost in the first scene.

The streak says 400 days. The anime still needs English subtitles. Textbooks are slow, Anki takes a weekend to set up, and nobody tells you what to learn next.

How it works

Watch. Click. Remember.

The extension on Netflix

Watch something you like.

Netflix, YouTube, Disney+, Viki, or any website. Migaku turns every word in the subtitles into something you can click.

A Netflix scene with Spanish subtitles

…o aceptar las consecuencias

aceptar

to agree to take on what follows from earlier decisions

Click the words you don't know.

See what it means in that exact line, and hear it. One more click saves it as a flashcard, with the audio and a screenshot.

The Migaku app: Study all decks

Review on your phone.

Each card comes back right before you'd forget it, so the word sticks. On the train, in bed, between episodes.

Starting from zero?

First, the words that show up everywhere.

Courses teach you the most common words and grammar first, the ones that make up 80% of what you'll watch and read. Kana and kanji come with mnemonics. (Yes, there's a rabbit hiding in ら.)

Then the shows start making sense.

Why Migaku

Subtitles, dictionary and flashcards in one place.

No more subtitle extension, dictionary tab, Anki and a pile of add-ons that break when you update one. Migaku is one account, on your laptop and your phone.

In their words

"I don't dread opening the app every day."

“Doing Migaku with Korean its been like 3 months or so and I feel farther than I got in my first 3 years of traditional study.”

App Store

“Well worth it, makes sentence mining insanely easy and I learned thousands of words using it.”

The honest part

It works if you show up.

Skip a week and reviews pile up.

That's how spaced repetition works. A little every day beats a lot on Sunday.

Sometimes Netflix or YouTube change their sites.

When that breaks something, we usually ship a fix within days.

Some languages are newer than others.

Japanese, Chinese and Korean have the most courses. Newer ones start in Early Access.

Questions

Which languages can I learn?+

Japanese, Korean, Chinese, Cantonese, Spanish, French, German, Italian, Portuguese, Vietnamese and English. Japanese, Chinese and Korean have the most courses so far.

I'm a total beginner. Is it too early?+

No. Start with the course for the most common words, then move to shows as soon as the score says you're ready.

I'm already advanced. Is there anything for me?+

Plenty: monolingual dictionaries, your own subtitle files, importing the words you already know, hotkeys for everything, and cards for whole dialogues.

Do I still need Anki?+

No. Migaku has its own flashcard reviews on phone and desktop.

What do I need to install?+

The Chrome extension for watching on your laptop, and the app on your phone. Setup takes a couple of minutes.

What if something breaks?+

Tell us at migaku.com/feedback or on Discord. We ship updates every week or two, and fixes for site changes usually within days.
