What is OpenCat?

OpenCat is a cross‑platform AI chat client available for macOS and iOS that lets users converse with AI through text, voice, and image interactions. The app includes a text‑to‑image engine that turns prompts into visual graphics and a translation feature that converts text between languages.

Users can employ the built‑in keyboard extension to invoke AI in any native app, and Siri shortcuts enable hands‑free access without opening the app. The interface supports Markdown formatting for clear, structured responses and offers a library of prompts for quick setup.
