What is Message AI?
Message AI (listed on the App Store as Message AI - GPT TTS) is an AI chat app for iPhone, iPad and Mac. It puts a GPT-powered assistant in a familiar messages-style interface: ask questions, get instant answers, and keep every conversation synced across your devices through iCloud. A library of built-in prompts covers common tasks, and you can create custom prompts that sync alongside your chats.
Beyond plain chat, the app adds text-to-speech so replies can be read aloud, and text-to-image generation using integrated Stable Diffusion. A keyboard extension brings the same assistant into any app, and Shortcuts and Siri support make it reachable without opening the app. Chats can be grouped and categorized, searched by history and prompt, and managed with bulk operations; font size and context length are adjustable.
The app is free to download with basic chatting; advanced models, text-to-speech and image generation unlock through in-app purchases (GPT subscription, text-to-speech, Stable Diffusion cloud service). It is aimed at Apple ecosystem users who want quick AI assistance with continuity across iPhone, iPad and Mac.
