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.
