AI Refine Keyboard

Read full description

AI Refine Keyboard is an action keyboard for iPhone built for voice-first writing. Less Typing – Better Writing! Use Speech to dictate, turn your voice into text, then improve or translate it in the same flow without leaving the app where you are already writing. Switch to it in Messages, Mail, Notes, browsers, and other apps to speak naturally, polish wording, and insert the result with Replace or copy it with Copy. VOICE INPUT (SPEECH) Choose Speech on the keyboard to dictate. iOS may briefly open the main app so the microphone can record; you can return to your chat and use Stop or Cancel from the keyboard. After transcription, run Improve or Translate on the result like any other text. Recording time and tokens apply (see the main app and on-keyboard token indicator). IMPROVE YOUR TEXT Select what you wrote or use the text from Speech and tap Improve. Choose a tone (polite, friendly, or neutral) and get two refined versions (v1 and v2) so you can pick the one that fits. Tap Replace to swap the selection, or Copy to use the result elsewhere. TRANSLATE FAST Tap Translate for your primary target language. Enable a second target language to unlock Translate 2, ideal when you often switch between two languages (for example English and Spanish) without digging through settings each time. Source language is detected automatically. WORKS ACROSS APPS Use AI Refine Keyboard anywhere the system keyboard appears. Dictate replies, refine drafts before you send them, translate messages, and keep two translation targets one tap away. PRIVATE BY DESIGN Requests run only when you tap Improve, Translate, or complete a Speech transcription flow. Only the text you explicitly work with is sent for processing. We don't log keystrokes or read your conversations in the background. SUBSCRIPTION & TOKENS AI Refine Keyboard offers plans with a monthly token allowance for Improve, Translate, and Speech (dictation and transcription) actions. You can upgrade your plan or purchase extra tokens when you need more. Manage everything in the main app. We’re exploring ways to let purchases work more smoothly for users who prefer not to sign in.

Type it messy. Send it right. KeyFlow is an iPhone keyboard with AI writing tools in the row above your keys. Write your message the way you'd say it, then tap once to fix the grammar, make it shorter, change the tone or translate it. Every change is highlighted before it replaces your text, and the original is one tap away. ONE ROW, EVERY APP • Fix Grammar: spelling, punctuation and grammar. • Improve Writing and Make Shorter. • Change Tone: professional, friendly, casual or formal. • Translate between English and Spanish. • Explain This and Ask AI, without leaving the chat. • Snippets: save the lines you type every week and send them in one tap. • Your own actions: write a prompt once and it becomes a button. WRITE IN YOUR LANGUAGE AI actions reply in the language you wrote in, so they work in many languages. Typing, autocorrect and predictions are in English and Spanish; switch with the globe key. FIX JUST ONE SENTENCE Select a sentence and KeyFlow rewrites only that part. The rest of your message stays exactly as you wrote it. PREFER TO TALK? Record in the KeyFlow app and use the transcription in your writing. Dictation needs microphone access and an internet connection. START FREE Eligible installs include a limited AI trial and the full keyboard. Choose KeyFlow Pro for managed AI with nothing to set up, or Lifetime BYOK: pay once and use your own OpenAI API key, billed by OpenAI separately. Pro has usage limits. Plans, limits and your local price are shown in the app before you buy. Restore purchases at any time. YOU DECIDE WHAT'S SHARED Ordinary typing shares nothing with AI. An AI action sends the text you selected to OpenAI (with nothing selected, the current field); dictation sends the recorded audio. AI sharing needs your permission and can be turned off in Settings. Keyboard AI also needs iOS Full Access. No KeyFlow account. Works in Messages, Mail, Notes, WhatsApp and other apps with standard text fields. Password fields always use the system keyboard.
