OpenCatAI Conversational ChatOpenCat is an AI connectivity tool for macOS, iOS, and iPadOS that brings models such as OpenAI, Claude, and Gemini into native applications. Users can configure these services and chat within the app, or use system-level keyboard extensions to translate, rewrite, explain, and continue selected text in email, documents, or browsers. The tool supports Markdown rendering, text-to-speech, voice activation, and chat synchronization across some devices. It is suited to Apple ecosystem users, content creators, developers, and professionals who want to manage their own model configurations. In practice, users generally need to prepare the relevant API keys, while model costs and available capabilities depend on the connected services.038.2All tools with this tag are shown.
