## What is Bikey?

Bikey is a bilingual keyboard for people who naturally type in Japanese and English together.

Instead of switching between Japanese and English keyboards again and again, you can type mixed romaji in one flow.

For example:

kyounomeetingha3jini
→ 今日のmeetingは3時に

korekara we can get in the car
→ これから we can get in the car

Bikey detects which parts are Japanese and which parts are English, then converts the Japanese parts while keeping English words as they are.

It is made for bilingual students, international friends, work chats, study abroad, and anyone who switches between Japanese and English every day.

Features:

Type Japanese and English in one keyboard
No constant keyboard switching
Mixed romaji input support
Japanese romaji to kana/kanji conversion
English words stay in English
Works directly from your iOS keyboard

Bikey is still early, so some conversions may not be perfect yet. But if you often type Japanese and English together, it should make texting feel much smoother.
