Question: Is there a native Mac app that supports multiple AI models and provides a customizable AI assistant for specific tasks?

Another powerful option is Alice, a productivity-focused desktop app that supports multiple AI models including GPT-4, Vision, Perplexity and Claude. Alice has more than 100 built-in prompts, keyboard shortcuts and the ability to create custom prompts. It also has automations to run actions in other apps and remote actions via webhooks, so it's good for tasks like scheduling social media posts and managing Google Calendar events.

If you want a more basic but integrated AI experience, check out Invisibility. This tool is designed as a personal copilot built into the Mac operating system, letting you use multiple AI models without having to juggle multiple subscriptions. It's got selective app sharing, full-screen sharing and keyboard shortcuts for quick information retrieval, all designed to make your work easier and more productive.

Last, Private LLM is an AI chatbot for iOS and macOS that uses a variety of open-source LLM models without needing a network connection. It's got full privacy and security features, customizable system prompts and integration with Siri and Shortcuts. It's good for people who want a private, offline AI assistant that works in multiple languages and can perform more advanced AI language processing tasks like grammar checking and summarization.
