Translate

Start in your language. Finish with Japanese you can use.

Translate turns the selected non-Japanese passage into natural Japanese while protecting its intent, structure, specificity, and level of politeness.

Japanese output, not a chat response

Kaku returns one Japanese translation and nothing else. It preserves names, dates, numbers, links, ticket IDs, list structure, sentiment, and action ownership.

When the idea comes first in another language

Draft the thought clearly in your strongest language, then translate it where you plan to send it. If a different Japanese register is needed, apply it and run Tone Converter next.

Translate without leaving the draft

Select a non-Japanese passage and bring natural Japanese back to the same field.

Select the source text

Choose the non-Japanese sentence or passage you want to use.

Translate to Japanese

Kaku infers the source language and preserves the message and formatting.

Preview and apply

Review the Japanese result before it replaces the selected source text.

Before and after

A direct path to usable Japanese

The translation keeps the workplace update concise and preserves its positive meaning without adding new detail.

Before

I've reviewed the document. Everything looks good.

After

資料を確認しました。問題ありません。

Only the translation you request

Translate sends the selected passage and limited context to Kaku AI after you explicitly trigger it. Code and non-prose content are left unchanged.

Translate at the point of communication

Use Translate in supported desktop writing fields, then continue editing or run Tone Converter without moving the message between tools.

Install Kaku on your desktop.

Kaku is a lightweight desktop app — not a browser extension. Sign in with Google after install to enable cloud features.
