What is Keyboard AI?
Keyboard AI (also known as AI Keyboard・ReplyAssistant) is an AI-powered keyboard extension app for iOS that serves as an ultimate writing assistant. Powered by the ChatGPT API from OpenAI, it works seamlessly across any platform or app on your iPhone, allowing users to generate contextually relevant replies, check grammar, translate text, paraphrase content, and find synonyms without leaving their current app.
The app offers multiple ways to use its features: the in-app method where users write or paste queries, the Generate Reply option in the iOS share menu, and the custom ReplyAssistant keyboard that can be activated by long-pressing the Globe button. Keyboard features include Grammar Check, Translate, Paraphrase, Find Synonyms, Continue (AI continues your text), and Custom Prompts. App features include Write (generate content with custom tone), Reply (craft responses to messages), and ChatPDF (upload PDFs and ask questions).
Keyboard AI is designed for anyone who wants to improve their writing efficiency on iOS devices - from professionals needing to craft emails quickly to everyday users who want to avoid typos and grammar mistakes. It supports multiple languages including English, Arabic, Chinese, French, Japanese, German, Spanish, Turkish, and Russian, making it ideal for multilingual users and international communication.
