日本語

The flashcard app that gets Japanese.

Learn Japanese words in a few minutes a day, from your first hiragana to the words in this week’s lesson. Every card shows you how to read the kanji until you don’t need the help.

It comes back just as it starts to fade.

Each time you remember a word, Lymi waits a little longer before showing it again. A few minutes a day is enough, and the words you learned months ago stay with you.

One kanji, seven sounds.

The same kanji sounds different in different words. Lymi shows the reading over the kanji until you know the word, then takes it away so you learn to read it on your own.

日 (ひ), 日本 (に), 毎日 (にち), 休日 (じつ), 日曜日 (び), 三日 (か), 今日 (きょう)

ひ · Sun; day

Same sound, different word.

はし can mean chopsticks, a bridge or an edge. Only the pitch tells them apart. Lymi charts it under the word, so you learn how it’s said as well as how it’s read.

Hear how it’s really said.

Every card is read aloud by a native Japanese AI voice. It follows the reading on your card, so 明日 is あした and 今日 is きょう. Tap a word to hear it. If your deck has its own recordings, those play instead.

Type one word. Get a whole card.

Add a word from today’s lesson and AI fills in the reading, the meaning, an example and a hint to help you remember it. It only fills what you left empty, and marks what it wrote.

Term乗り換
ReadingAIのりかえる
MeaningAITo change (trains, buses)
ExampleAI次つぎの駅えきで乗のり換かえます。No reading over 次 and 駅: you already know them.
HintAI乗る to get on, plus 換える to swap: you get on a different train.

Turn a textbook page into cards.

Take a photo of your textbook or notes. The new words become cards with their readings, and you pick the ones to keep.

Bring your own AI.

Connect Claude, ChatGPT or another assistant once. Send it a photo of today’s page and it adds the new words, or ask what’s waiting for you tonight.

Learning is more fun together.

Review a deck with your class, your tutor or a friend. One of you adds the words after each lesson and shares a link, and everyone reviews on their own schedule.

Built with Japanese in mind.

The small things that matter once you’re a few weeks in.

Kanji in Japanese shapes

Some kanji look different in a Chinese font. Lymi shows your cards in Japanese forms, the way kanji look in Japanese books.

Type でんしゃ or デンシャ and find 電車.

Readings only where you need them

In example sentences, furigana stays over the words you’re still learning and leaves the ones you know.

Bring your Anki deck

Coming from a deck like Kaishi 1.5k? Word recordings and pitch accent stay on the cards, and sentence translations come along too.

Questions before you start.

Do I need to know kana first?

Yes, because every reading is written in kana. Start with the kana deck, and add N5 words once the signs feel familiar.

Does Lymi show romaji?

Words show their reading in kana over the kanji. The kana deck is the one place with romaji, because there the sound is the answer.

What does a card ask me?

One way at a time: the Japanese for its meaning, or the meaning for the Japanese. You think of the answer, turn the card over and say how well you knew it. There’s nothing to type.

How does Lymi know I know a word?

When its card reaches Known in your reviews. From then on the reading steps aside, on that card and in example sentences across your decks. Forget the word once and the reading is back, and turning a card over always shows it.

How does the voice know how to read a kanji?

It reads from the reading on your card, so a word that can be read several ways is said the way your card has it.

Can I bring my Anki deck?

Yes. Cards keep their readings, their schedule and their word recordings. Sentence recordings stay behind.

Does it work on my phone?

Yes. Lymi runs in the browser on your phone and your computer, and you can add it to your home screen. Your cards and progress are the same on both.

What does it cost?

Nothing. Lymi is free to use.
