Sound fluent in English. Even when you're drafting.
Real-time tone correction, grammar, and translation — for the millions of iPhone users writing in their second or third language. Works in every app.
English internet writing has unwritten rules — register, idiom, formality — that take years to absorb. An AI keyboard collapses that gap: write what you mean in your second language, get back a version that reads like a native wrote it.

FAQ
Will an AI keyboard help me write better English?
Yes, particularly the tone and paraphrase tools — they smooth phrasing that "sounds translated" into natural native English. Over time, watching the AI fix your drafts also helps you internalize the patterns.
Does KeyAI support typing in my native language?
Yes — 60+ keyboard layouts, including Spanish, French, German, Portuguese, Italian, Russian, Polish, Turkish, Arabic, Hebrew, Hindi, Japanese, Korean, Chinese, Vietnamese, Thai, Indonesian, and dozens more.
Can I use AI tools in my native language too?
Yes — tone change, paraphrase, summarize, and ask-AI all work in 30+ languages. Write a German email, tap *Tone → Professional*, get back a more polished German version.
How is this different from Grammarly?
Grammarly catches grammar mistakes. KeyAI does grammar PLUS tone-shifting, translation, paraphrasing, and ask-AI — all from inside the iPhone keyboard, in 55+ languages. Grammarly is English-only.
