CherryHQ/cherry-studio ? reverse-engineered prompt

Build me a desktop AI productivity studio that works on Mac, Windows, and Linux. I want a single app where I can connect to all the major LLMs like OpenAI, Anthropic, and Gemini, but also web-based AI services and local models running through Ollama. The main idea is to have a unified client for everything.

The app should come with hundreds of pre-configured AI assistants for different tasks, and I should also be able to create my own custom ones. A key feature is being able to have simultaneous conversations with different models. It needs to handle various file types like PDFs and images so I can ask the AI questions about their contents. For the design, let's go with a clean, modern UI that has both light and dark themes, maybe even a transparent window option, and great Markdown support for displaying formatted text and code.
