About this app

Prompt AI Keyboard is an AI keyboard that writes, fixes, translates and answers — in every app you already use. Type the way you normally do, tap ✨, and your text comes back better: a sharper prompt for ChatGPT, a cleaner email, a friendlier reply, or the same sentence in Spanish.

ONE KEY, 14 THINGS IT CAN DO
Hold the ✨ key and pick what a tap does:
• Enhance prompt — a rough idea becomes a prompt an AI can actually work with
• Fix grammar — cleaned up, still your voice
• Rewrite — make it shorter, make it longer, or say it another way
• Change tone — professional, friendly, casual, confident or empathetic
• Translate — type in your language, send in theirs
• Continue writing — it picks up where you stopped, your words untouched
• Ask AI — ask a question in the text field and the answer appears below it
• Reply — copy the message you got, tap once, get an answer to send
Every mode is free. The key remembers your pick, so a tap always does what you meant.

TRANSLATE AS YOU TYPE
47 languages, picked from a row of flags above the keys. Write in the language you think in and send it in the one they read — in chats, email, comments, anywhere.

VOICE TYPING
Tap the mic and speak. Your words arrive as clean text with punctuation, ready to send or rewrite.

PROMPTS MADE FOR EACH AI
Pick who your prompt is for and it is written to suit them: Any AI, ChatGPT, Claude, Gemini, Grok, Perplexity, DeepSeek, GitHub Copilot, Copy.ai, Midjourney, Ideogram and Suno. One-tap chips drop in Midjourney parameters, Suno song sections, Perplexity search operators and Copilot commands — and you can edit, reorder or replace the chips on any of them.

WHAT PEOPLE USE IT FOR
• Better ChatGPT prompts, without leaving the chat
• Detailed Midjourney image prompts and Suno music prompts
• Emails and messages that read the way you meant them
• Replying in a language you don't write well
• Turning rough notes into finished text — prompt engineering made effortless

A REAL KEYBOARD UNDERNEATH
✓ Autocorrect and suggestions that learn your words, on this phone
✓ Emoji with a recents tab, long-press alternates, key previews
✓ Light, dark or system theme, three fonts, adjustable key height
✓ Keypress sound and haptics, with strength you control
✓ Drag your AI targets into your own order and hide the rest
✓ Works wherever you type — messages, mail, notes, browsers, every app

NOTHING GETS LOST
Undo puts your original back instantly, and Retry runs again from that original — not from the version you just got. Recent rewrites are kept on the phone so you can copy one again.

FREE & PRO
Free: 5 rewrites a day plus daily voice typing — every mode, every language, every setting.
Pro: a daily cap you won't hit, our best AI model on every rewrite, hours of voice typing, and your last 20 rewrites saved instead of 3.
Monthly or annual. The annual plan starts with a 7-day free trial. Cancel anytime.

NO ACCOUNT, NO TRACKING
You never sign in. Text is sent only to produce your rewrite — prompts are never stored and never used to train AI models. Learned words and your rewrite history stay on this phone, erasable in Settings.

Built for anyone who writes on a phone — creators, developers, marketers, students, and everyone who talks to AI every day.

The best writing doesn't start in another app. It starts where you type.
