Furigana Keyboard Ruby IME

Furigana Keyboard Ruby IME is a Japanese furigana keyboard for creating text in Kanji(reading) format as you type.

It is built for worksheets, learning materials, reading notes, shared documents, messages, and any place where the reader needs pronunciation next to kanji. Choose a Japanese candidate and insert text with ruby readings without manually adding furigana afterward. For longer passages, paste text into the main app and convert the full passage at once.

This furigana keyboard is useful for teachers, parents, Japanese learners, reading notes, and anyone who wants to share easier-to-read Japanese text. It supports both 12-key kana input and romaji input, so you can create kanji with readings in a familiar Japanese keyboard flow.

What you get:
- 12-key kana input and romaji input
- Candidate confirmation as Kanji(reading)
- Reading conversion for selected text or recent Japanese text near the cursor
- Long text conversion in the main app for pasted passages
- Furigana and ruby reading support for worksheets, notes, study materials, and shared documents
- No ads, analytics, or in-app purchases
- No Full Access required
- No typed content sent to external servers

Examples:
例えば -> 例(たと)えば
日本語 -> 日本語(にほんご)
食べる -> 食(た)べる

Privacy:
This keyboard does not require Full Access. Typed content is not sent to external servers, and conversion and learning are processed on device. The app does not include ads or analytics.

Note:
For existing-text conversion inside other apps, the keyboard extension uses selected text or a limited amount of nearby text before the cursor. To convert a longer passage in one step, use the long text conversion field in the main app.

Due to iOS keyboard extension behavior, iOS may switch to the system keyboard in password fields and some special input fields.
