Suisui（スイスイ）日本語入力キーボード｜ライブ変換

Nyarrow Studio

About this app

Suisui is a Japanese input keyboard that ensures your fingers never get lost, even when switching devices. It faithfully reproduces iPhone, Galaxy, and Gboard-style key layouts, allowing you to type with the same feel whether using flick input or QWERTY. Furthermore, it features "Live Conversion," which automatically converts kana characters into kanji as you type. This significantly reduces the back-and-forth of pressing the conversion key, searching for candidates, and selecting. Both conversion and predictive text are handled by a small AI within the device, so your input is never shared externally.

■ Stay with your familiar layout even when switching devices
"I switched to Android, and the key positions changed, making it difficult to type."
Suisui allows you to choose between iPhone, Galaxy, and Gboard-style key layouts.
Both the 12-key flick input and the QWERTY keyboard are perfectly matched, including the placement of symbols and punctuation marks,
allowing you to use it from day one, maintaining the rhythm your fingers are accustomed to.

■ Just type, and the sentence will be completed (Live Conversion)
If you type "Today's meeting is from 3 o'clock," "Today's meeting is from 3 o'clock" will appear in your hand.
Just keep typing the words that come to mind.
You can concentrate on writing and, as the name suggests, write smoothly.

■ Read the context and use the correct kanji
It reads the surrounding sentences and selects the correct homonyms.
After writing "I listened to a lecture," "kouen" becomes "lecture."
After "I played in the park," it becomes "park."
This reduces the effort of retyping after confirming.

■ Strong in names of people and places
"Yamada Tarou" becomes "Yamada Tarou," and "Shibuya" becomes "Shibuya."
It has a built-in dictionary of approximately 310,000 words including names of people, places, and organizations, and converts full names (surname and given name) all at once.

■ Subtle Follow-Up Even After Confirmation
Even if you confirm a mistranslation without noticing, it gently suggests, "Did you mean ◯◯?"
You can correct it with a single tap.

■ The More You Use It, the More It Becomes Familiar with Your Language
It remembers frequently used words and your chosen suggestions, and they will appear at the top of the list next time.
You can register words in the user dictionary or load dictionaries from other Japanese input methods.
You can delete learned content at any time from the settings.

■ On Tablets and Remote Desktops
On larger screens, you can choose between a split keyboard (left and right) or a floating display.
When remotely controlling Windows from your smartphone or tablet, it switches to a PC layout keyboard.
Ctrl, Alt, and function keys are all included.

■ Input Content Does Not Leave Your Device
Conversion, learning, and voice input all operate solely within your smartphone.
It doesn't send text to the cloud for conversion, so it works as usual even in airplane mode or on the subway.
We don't collect input history for advertising.

In the password input field, all functions, including conversion, automatically stop.

*The warning displayed by Android when enabling the keyboard is common to all keyboard apps. Suisui disables all functions, including conversion, in the password input field and does not send input content outside the device.

*To improve bugs, you can voluntarily cooperate in sending non-personally identifiable bug information (default is off). Your input content will not be included.
