OpenCat AI is a native AI client designed for the Apple ecosystem (macOS, iOS, iPadOS). It works by integrating the API keys for your own OpenAI and other services, delivering a smoother, faster interactive experience than the web version.
There is a basic free version. Paid options include Pro and Cloud AI versions; exact pricing and feature differences are available in-app or on the official site.
Using OpenCat AI mainly requires configuring your own AI service API keys in the app’s settings; the app itself does not require a login.
It supports APIs for popular models such as OpenAI (e.g., GPT-3.5, GPT-4), Gemini, Claude, and more, with the option to customize provider domains.
Features include deep integration with Apple systems, such as a keyboard extension, Siri and Shortcuts support, a global floating window, and built-in translation and writing assistance.
OpenCat AI is designed for Apple devices and runs on devices with macOS, iOS, and iPadOS.
The app communicates with third-party AI services using the API keys configured by the user. For details on data handling, please refer to the privacy policy and the terms of the configured AI service providers.
It is suitable for individuals, creators, developers and teams who need efficient communication, writing assistance, creative generation, or coding on Apple devices.
