Message AI

Message AI, listed on the App Store as Message AI - GPT TTS, is an AI chat assistant app for iPhone, iPad and Mac. Users ask questions in conversations with the assistant and receive answers. Any number of conversations can be created, and all of them are synchronized between the user's devices through iCloud. It is made for people who want an AI assistant available across their Apple devices and inside other apps.

Message AI comes with built-in preset prompts, and users can write their own prompts, which also sync to every device. A keyboard extension gives access to the AI in any app, and the app can be used in Shortcuts and Siri. Text to image generation is integrated, including images made with the Stable Diffusion model; generated images can be previewed and dragged into other apps. A text to speech model reads responses aloud.

Conversation tools let users search conversation histories and prompts, select multiple conversations to manage them in batch, adjust the font size and set the context size. Message AI is free to download, with in-app purchases for a GPT-3.5 cloud service at $1.99, Text to Speech at $0.99 and Stable Diffusion at $0.99. It requires iOS 16.0 or later and macOS 13.0 or later, and the interface is available in English and 5 more languages.
