About this app
AI keyboard to fix grammar, rewrite in any tone, humanize AI text and reply.
Read full description
Preener is an AI keyboard for Android that fixes grammar, rewrites your message in the right tone and helps you reply. Type the way you normally do, tap a button above the keys, and the text in the box is fixed in place. No copying and pasting between apps. Fix grammar in any app Tap Fix grammar and your spelling, punctuation and wording are corrected right where you typed: in messages, email, social apps and anywhere else you write. It works like a grammar checker built into your AI keyboard. Changed your mind? Undo steps back one change at a time. Rewrite and paraphrase in the right tone Change the tone of a message: make it more professional, friendlier, more casual or more confident. Shorten it, simplify it or paraphrase it in clearer words. Preener rewrites the text and keeps what you meant. Humanize AI text Have a draft that sounds like a chatbot wrote it? Humanize turns stiff, AI-sounding text into writing that reads like a real person wrote it. Reply to messages in one tap Copy a message you got and tap Reply to clipboard, or paste it into the app, and Preener suggests replies that fit. Pick one, adjust it and send. Voice typing that writes for you Just talk. Voice typing turns what you say into clean, punctuated text, ready to send. 107 writing actions Write a cover letter, resume bullets, a work email, a follow-up email, a LinkedIn post, an apology, a birthday wish, an Instagram caption, a product description or an essay outline. Search the actions, browse them by category and keep your favorites close. Your style, every time Tell Preener how you write, for example short sentences, plain words or no emojis, and every result follows it. A complete keyboard Swipe typing, autocorrect, word suggestions, emoji search, a clipboard, text shortcuts, and themes with nine key styles and more than fifteen colors, each in light and dark. Never lose a draft Your work saves as you go, and the results you like stay in your Library. One account everywhere Sign in with Google or a 6-digit code sent to your email. The same account works on the web at preener.ai, with your saved writing and your plan. Private by design - Word suggestions and your typing history stay on your phone. - Text is sent to Preener only when you use an AI feature, such as an action, replies or voice typing. - AI features never run in password fields. - Results you don't save leave your history within 24 hours and are erased within 30 days. - Voice recordings are not stored. - We don't use your writing to train AI models. - App usage analytics is always on and never includes what you write. - Settings and personal dictionary backup are separate options, both off by default. - No ads and no advertising ID. - You can delete your account. Your account, saved writing and files are erased within 30 days; usage records, which contain none of your writing, are kept but no longer linked to you. Android shows the same notice for every keyboard that isn't built in when you turn it on. It is standard and not specific to Preener. Free and Pro An account is required. The free plan includes AI help every day, 5 minutes of voice typing a day and all 107 actions. Preener Pro gives you about 10,000 AI actions a month and 2 hours of voice typing a day, billed monthly or yearly through Google Play, and works on the same account on the web. The Pro allowance is given daily, and very long texts count as more than one action. Preener works in English for now. Requires Android 7.0 or later.
