Stuck on what to text back? ReplyMate writes five different replies to any message, in the style you pick, right from your keyboard. REPLY FROM ANY CHAT • A full keyboard with AI replies built in. Copy their message, tap Reply, tap the reply you like. Tap another one to swap it. • Keep typing on the same keyboard to tweak the reply. No switching back and forth. • Works in messaging, social and dating apps, and anywhere else you can type. FIVE REPLIES THAT ARE ACTUALLY DIFFERENT • Every reply is a different angle and a different length, not five versions of the same line. • Replies match their language, from English to Spanish, Chinese and more. The app and keyboard come in 21 languages and follow your iPhone's. • 22 styles: Natural, Funny, Flirty, High EQ, Romantic, Comfort, Roast, Soft No, Tease and more. SCAN A CHAT SCREENSHOT • Pick a screenshot of the conversation and ReplyMate reads who said what, so replies fit the whole chat. • Screenshots are read on your iPhone. Only the text is sent, and you can edit it first. PRIVATE BY DESIGN • Nothing is sent until you agree, and you can withdraw that anytime in Settings. • The keyboard never records or sends what you type. It reads the message you copied only when you tap Reply. • No account, no ads, no tracking. Favorites stay on your device. FREE AND PRO • Free: 20 reply sets a day (100 replies), every style, in the app and the keyboard. • Pro raises the limit to 10,000 a day. Same features, no tricks: no hidden trial and no weekly charge. Replies are written by AI. Read them before you send them.
