A real sample, unedited

Rashomon (羅生門) — Akutagawa Ryūnosuke · From the opening pages · Japanese → English · unedited output, furigana not shown

ある日の暮方の事である。一人の下人が、羅生門の下で雨やみを待っていた。

It was toward evening one day. A servant was waiting beneath Rashomon Gate for the rain to stop.

雨は、羅生門をつつんで、遠くから、ざあっと云う音をあつめて来る。夕闇は次第に空を低くして、見上げると、門の屋根が、斜につき出した甍の先に、重たくうす暗い雲を支えている。

Rain enveloped Rashomon Gate, gathering from afar a rushing sound. The evening gloom gradually lowered the sky, and when one looked up, the gate’s roof supported heavy, dim clouds on the tips of its roof ridge, which jutted out obliquely.

下人は、大きな嚔をして、それから、大儀そうに立上った。夕冷えのする京都は、もう火桶が欲しいほどの寒さである。風は門の柱と柱との間を、夕闇と共に遠慮なく、吹きぬける。丹塗の柱にとまっていた蟋蟀も、もうどこかへ行ってしまった。

The servant gave a great sneeze and then rose wearily. Kyoto, chilled by the evening cold, was already cold enough to make one long for a brazier. The wind blew without restraint between the gate’s pillars along with the evening gloom. Even the cricket that had been perched on a vermilion-lacquered pillar had already gone somewhere.

What the translation reads like

  • This 1915 story comes out as calm, readable English prose that stays close to each sentence.
  • Names of places are written in romaji, such as Rashomon Gate and Kyoto. The glossary pass fixes each name once, so it reads the same in every chapter.
  • Old objects get a plain English word, such as brazier for 火桶, so you can read on without looking things up.
  • The AI reads the furigana along with the kanji, and the English does not repeat the readings. The original text, with its furigana, stays above each translation.

See it before you try it

Pride and Prejudice — Jane Austen · Chapters 1–2, sample · English → Simplified Chinese

It is a truth universally acknowledged, that a single man in possession of a good fortune must be in want of a wife.

凡是有钱的单身汉,总想娶位太太,这已经成了一条举世公认的真理。

However little known the feelings or views of such a man may be on his first entering a neighbourhood, this truth is so well fixed in the minds of the surrounding families, that he is considered as the rightful property of some one or other of their daughters.

尽管这样的男人第一次来到一个地区时,他的感情或看法如何,人们知道得很少,但这条真理在邻近的各个家庭中却是如此根深蒂固,以致于他被视为他们某个女儿理所当然的财产。

“My dear Mr. Bennet,” said his lady to him one day, “have you heard that Netherfield Park is let at last?”

“亲爱的班纳特先生,”他的太太有一天对他说,“你听说尼日斐花园终于出租了吗?”

Built for whole books

Names stay themselves

Before translating, we read through your book and build a glossary of people, places and special terms. Every request carries it, so “Mr. Darcy” is the same person on page 3 and page 300, and you can edit the glossary yourself.

Questions, answered

How are Japanese names translated?

Names are written in romaji. Before translating, the AI reads the book and makes a glossary, so every name is written the same way in every chapter. You can review and edit the glossary too.

What happens to honorifics like san and sama?

You decide. Write an instruction such as “keep Japanese honorifics like san and sama” in the optional Translation style box in your account settings before you upload. You can also review and edit how each name is written in the glossary.

Is furigana kept?

Yes. The original Japanese text is not changed, so furigana stays in place above the kanji. The English translation below each paragraph does not repeat the readings.

Can I translate light novels or web novels with this?

You can translate any ePub file you have the right to use, such as your own writing, books you bought without DRM, or public domain classics. We do not provide books, and files with DRM cannot be opened.
