Keyboard AI・ReplyAssistant: Smart AI Reply Keyboard
ReplyAssistant is an AI-powered custom keyboard for iOS that instantly generates smart, context-aware replies for any app. Type less, communicate faster, and never stare at a blank text box again.
Overview
Keyboard AI・ReplyAssistant transforms your iPhone's typing experience by embedding generative AI directly into your keyboard. Instead of switching between apps to brainstorm responses, users can generate contextually relevant replies right where they're messaging, whether that's texting a friend, replying to a work email, or commenting on social media. The app comes packed with a diverse library of prompts covering tone, intent, and style, so you always have the right words on hand.
Beyond simple reply generation, ReplyAssistant doubles as a grammar checker, paragraph formatter, and translator, making it a versatile communication companion for multilingual users and busy professionals alike. Its flexibility shines through two usage modes: compose directly within the app's input field, or select and share text from any other app to generate a reply on the fly. With custom prompt creation, users can tailor the AI's output to match their personal voice or specific professional needs, making every interaction feel authentic rather than robotic.
