An AI keyboard that speaks fluent prompt
Better questions get better answers. This keyboard applies real prompt engineering to whatever you type — without leaving the conversation.
One-tap Enhance
Type your idea however it comes out — half-formed, no punctuation, whatever. One tap rewrites it in place as a clear, model-ready prompt. No library to search, no template to fill in.
Your rewrites are saved
Every rewrite is kept on the phone, so you can go back for the version you liked instead of writing it again.
On-device only — never uploaded, and you can wipe the list from Settings whenever you like.
Tuned for 10+ AI tools
Pick your target and the instructions change completely — a Midjourney prompt is built nothing like a ChatGPT one, and a Perplexity search nothing like either.
The syntax, one tap away
Chips above the keys insert what each tool actually parses: --ar 16:9 for Midjourney, [Chorus] for Suno, site: for Perplexity, /tests for Copilot.
Nobody remembers all of it. Now you don't have to — and the list is yours to edit.
Attach, don't paste
Copy a job ad, an error log or the message you're replying to, then tap the clipboard key. It travels as reference, so the AI works from it instead of rewriting it.
Pasted inline, the model can't tell your instruction from your material. This is the fix.
Every rewrite is reversible
Enhance replaces what you wrote, so Undo and Retry sit there for a few seconds afterwards. Retry starts from your original words, never the rewrite — a fresh take, not a copy of a copy.
More than a prompt enhancer
Hold the Enhance key and it becomes something else: a copy editor, an eraser, a tone dial. The prompt you're writing is only one of the things it fixes. All five modes are free to use — they draw on the same daily allowance.
- Enhance promptWhat a tap runs by default. Full prompt engineering, built for whichever AI you've picked.
- Fix grammarSpelling, grammar and punctuation — nothing else. Your voice, your slang and your length stay exactly as you wrote them.
- Make shorterAbout half the length, with every fact, request and commitment still in it. Shorter, not blunter.
- Professional toneClear and courteous, fit for work. Slang and venting out; the actual request intact.
- Friendly toneWarm and conversational. Softens anything curt without going vague about what you're actually asking for.
The menu picks; it doesn't run. Choose a mode and it stays chosen — the keycap starts carrying that mode's mark, and from then on a plain tap runs it. So if you spend your day fixing grammar, that's what your Enhance key is.
Or turn it off entirely. The key keeps its place and its width, so nothing shifts under your thumbs — it just stops rewriting, and a tap opens this menu instead.
…and underneath it, a keyboard you'd use anyway
Nobody keeps a keyboard that types badly, however clever its AI button is. So the boring parts came first: correction, suggestions, emoji, accents. Enhance sits on top.
Autocorrect built for thumbs
It knows a typo from a thumb slip. A t where you meant r is scored as what it is — the next key over — so teh becomes the, not ten.
And it holds back when it should: type hel and nothing happens, because you're on your way to hello.
It learns your words
Names, slang, product codes, the way you actually write. Use a word twice — or undo a correction once — and the keyboard stops fighting you.
That list never leaves your phone. Wipe it from Settings whenever you like.
Emoji, accents and previews
A full emoji panel with a Recent tab that fills itself in. Hold any letter for its accents — à, ä, å — and every key shows the bubble that tells you what you actually hit.
Voice typing Android
Tap the mic and talk; the transcript lands in the field, ready to enhance.
Android only — Apple blocks iPhone keyboards from the microphone entirely, so we show no mic there rather than one that can't work.
Works in every app
It's a real system keyboard, not another app to open. Enhance is there in ChatGPT, in Safari, in Slack, in your notes — anywhere you can type.
Same keyboard, both phones
iPhone and Android run the same engine: same corrections, same targets, same rewrites. Switch phones and nothing changes.
Prompt engineering in three taps
No app to open, no prompt library to memorize, no course to take first. It happens in your keyboard.
Type your rough idea
A few messy words are enough. "make logo for coffee shop, warm vibes" works fine.
Pick a target & tap Enhance
Choose who you're talking to — ChatGPT, Claude, Midjourney, Suno and more — then hit the ✦ Enhance key. Hold it instead for grammar, tone or length.
Send the polished prompt
Your text is replaced with a prompt built for that AI. Read it, tap Undo if you'd rather not, send.
The same idea, before and after. The Perplexity search operators at the bottom came straight from the chip row above the keys.
"research on intermittent fasting"
Summarize peer-reviewed research published since 2024 on intermittent fasting and metabolic health. Prioritize systematic reviews and meta-analyses, cite every source, and flag where the findings conflict.
filetype:pdf after:2024 site:nih.gov10+ AI targets. You probably use two.
Every target you scroll past costs you a swipe. So the strip above the keys is yours to arrange: drag your AI to the front, switch the rest off, and it stays that way.
- Drag your targets into orderThe one you use most sits where your thumb already is. Hide the rest.
- Rewrite the chip rowsAdd the parameters you keep typing, drop the ones you never touch, reorder what's left. Every target is editable — even the ones that ship with no chips at all.
- And the rest of itLight or dark. Taller keys or shorter. Three typefaces. Sound, haptics, auto-capitalization, the double-space period — a screen each, nothing buried three taps deep.
- All of it freeCustomization isn't the paid tier. Every bit of this works the day you install.
Your keyboard shouldn't be nosy
Keyboards see everything you type, so we built this one to see as little as possible.

Questions, answered
Everything people usually ask before installing a new keyboard.
Does the keyboard read everything I type?
No. It works entirely on your device as you type. Text leaves your phone only when you tap Enhance — and only what's in that one field. Nothing runs in the background, and your text isn't stored after the rewrite comes back.
Do I need an account?
No. There's no sign-up, and we never ask for your name, email or phone number. Daily limits are tracked with an anonymous, random install identifier that isn't linked to you.
Which AIs does it optimize for?
ChatGPT, Claude, Gemini, Grok, Perplexity, Copilot, Copy.ai, DeepSeek, Ideogram, Midjourney and Suno — plus an "Any AI" mode for everything else. Each one gets a prompt built the way that tool works best, and several add a row of quick-insert chips for their own syntax.
Can it fix my grammar too?
Yes. Hold the Enhance key for five rewrite modes: Enhance prompt, Fix grammar, Make shorter, Professional tone and Friendly tone. A plain tap always runs Enhance, so the fast path stays one tap. All five are free to use — they share the same daily allowance, and Pro lifts the cap.
Is it any good as an everyday keyboard?
That was the point — nobody keeps a keyboard that types badly. Autocorrect tuned for thumb slips, word suggestions above the keys, an emoji panel with a Recent tab, accents on long-press, key previews, auto-capitalization and the double-space period. It also learns the words you actually use, on your device.
Can I choose which AI targets I see?
Yes. In Settings, drag the target pills into your own order and switch off the ones you never use, so the AI you actually use sits first instead of buried at the end. You can edit each target's quick-insert chips too — add your own, remove ours, reorder. All of it free, not part of Pro.
Does voice typing work on iPhone?
No — voice typing is Android only. Apple doesn't give keyboard extensions access to the microphone, so no third-party iPhone keyboard can offer it. We show no mic button on iOS rather than one that can't work.
Is it free?
Free to download, with a free allowance of enhancements every day. Every rewrite mode is free to use; Pro raises the daily cap far past what a day's typing uses, puts a bigger AI model behind every rewrite, and saves a longer history. The App Store and Google Play handle payment — we never see your card details, and you can cancel anytime.
How do I enable the keyboard?
Install the app and follow its setup screen: on iOS, Settings → General → Keyboard → Keyboards → Add New Keyboard; on Android, Settings → System → Languages & input. Then switch to Prompt AI Keyboard with the globe key in any app.
What happens if I don't like the enhanced text?
Undo and Retry sit above the keys for a few seconds after every rewrite. Undo puts your original text back exactly as you typed it; Retry runs again from that original, so you get a genuinely different attempt rather than a rewrite of the rewrite. Nothing is sent to the AI you're chatting with until you press send yourself.
