One AI assistant for chat, images, and voice across all your Apple devices
Hold an unlimited number of conversations with a GPT-based assistant, grouped by category and searchable across your full history.
Conversations, presets, and custom prompts stay in sync automatically between iPhone, iPad and macOS through iCloud.
Reach the assistant from inside almost any app so you can generate or refine text without leaving where you are typing.
Turn a written prompt into an image, preview it in-app, drag it into other apps, and optionally use a StableDiffusion model.
Text to speech and voice AI across every device
Listen to books, PDFs, documents and web pages read aloud in a large library of lifelike AI voices.
Dictate instead of typing in almost any app, across Google Docs, Gmail, Slack, Outlook and more.
Turn documents or a short prompt into an AI podcast, and get instant summaries of what you are reading.
Use the web app, Chrome and Edge extensions, and native iOS, Android, Mac and Windows apps.
