## What is naitiveKey?

One word can change everything.
"naitiveKey" is a next-generation AI-powered Japanese keyboard that instantly transforms clunky, unnatural Japanese or English inputs into fluent, native-level Japanese expressions with a single tap.

"My grammar is correct, but does it sound too much like a textbook?"
"I want to type in English and have it instantly send as natural Japanese."
"I want to avoid robotic machine translations and use real, living expressions."

Whenever you face these challenges, simply tap the magic "Native" button. The AI analyzes your text and suggests 3 beautifully tailored, natural Japanese variations.

=== What the Magic "Native" Button Can Do ===

1. Refines Clunky Japanese into Fluent Phrasing
- Your input: "私、明日、行く、京都。一緒どう？" (Clunky Japanese)
- AI suggestions:
  - "明日京都に行く予定なんだけど、一緒に行かない？" (Friendly invitation)
  - "明日京都に行くんですけど、もしよかったら一緒に行きませんか？" (Polite invitation)
  - "明日京都行くから、タイミング合えば一緒に行こう！" (Casual plan)

2. Translates English Inputs Directly into Native Japanese
- Your input: "Would you like to grab food sometime?" (English thoughts)
- AI suggestions:
  - "今度よかったら美味しいものでも食べに行かない？気軽な感じで！" (Friendly & welcoming invite)
  - "近々ごはんでもどうですか？色々お話ししたいです！" (Warm, charming icebreaker)
  - "もしタイミング合えば、来週あたりごはん行きましょう！" (Casual & low-pressure plan)

Just tap your favorite candidate, and your text is instantly replaced!

=== Perfect For ===
- Japanese Learners: Graduate from textbook Japanese and sound natural in daily conversations.
- Global Communicators: Chat and post on social media with natural Japanese nuances.
- Bilingual Users: Think in English, type in English, and send as fluent Japanese instantly.
- Anyone wanting to avoid stiff, robotic machine translations.

=== Secure by Intent: Privacy You Can Trust ===
To enable the network-based "Native" button, iOS requires "Full Access" to be turned on. We hold user privacy as our absolute highest priority.

- [Intentional Transmission]: The only data transmitted is the specific text present on your screen at the exact moment you tap the "Native" button.
- [Zero Background Logging]: We never log, cache, or background-transmit your everyday keystrokes, passwords, or personal data.
- [Hybrid Offline Processing]: Basic typing and local conversions are processed entirely offline on your device. The connection is established only when you use the AI features, ensuring ultimate peace of mind.

=== Powered by a Acclaimed Engine (azooKey Base) ===
naitiveKey is built upon the highly acclaimed open-source Japanese keyboard engine, "azooKey." Enjoy the lightning-fast flick layouts, customizable settings, and local dictionary support of a premium keyboard, now supercharged with cutting-edge AI phrasing technology.

Express yourself more naturally, confidently, and dynamically in Japanese.
Tap "Native" and unlock the true flow of your words.
