Unicorn is an AI keyboard for Android. You install it once, switch your phone’s keyboard to Unicorn, and AI sits right above your keys in every app: WhatsApp, Instagram, Messages, Gmail or any text box. The problem: using AI to write means leaving the conversation. You copy your text into a chatbot, wait, then copy the answer back. And the questions you ask ChatGPT, Claude, Perplexity, Google and Grok end up scattered across five apps you can never search together. What the Unicorn keyboard does: Fix it before you send it. Type the way you text, tap Tone, and your message is rewritten in place: friendly, professional, shorter and more. Grammar and Translate (23 languages) work the same way, with one tap. Ask Unicorn. A prompt bar built into the keyboard. Type /reply to answer a message you copied, /email to draft a full email, or ask for anything. Tap the answer and it goes straight into the app you’re typing in. All your AI prompts in one place. If you turn it on, the keyboard saves the prompts you send in ChatGPT, Claude, Perplexity, Google and Grok to one private Library on your phone. Search it by meaning, and when you start asking something you’ve asked before, Unicorn offers your earlier prompt. A great keyboard first. Built on Android’s open-source keyboard engine (AOSP LatinIME), with our own glide-typing decoder, a number row, emoji, voice typing, resize and one-handed modes, and a touch model that learns your aim. Social. Everyone hatches a one-of-a-kind Unicorn with its own name and card to share. Near you shows playful hunches about what’s on your town’s mind, always labelled as guesses. People can opt in to share anonymous topic signals, and a community trend appears only once 25 people share it. AI by Meta: every AI tool in the keyboard runs on Meta’s Muse model through the Meta Model API, with Claude as an automatic fallback. Private by design: your prompts never leave your phone, password and banking fields get no AI and no saving, there’s no account to create, and it’s free.
