Haye is a private AI assistant that runs on macOS. It brings multiple top-tier AI models together in one app, so users can use them without switching between multiple tools (the models mentioned in the materials include DeepSeek, o3, GPT-4o, Claude-3.5, and Gemini-2.0, while elsewhere GPT-5, Claude Sonnet 4.5, DeepSeek R1, Gemini 2.5 Pro, and others are also mentioned).
Main capabilities include: chatting with any app, text, screenshots, and files on macOS; invoking Haye anywhere via the Command+E shortcut to ask questions or perform actions on any text or image; chatting with PDFs and local files to get answers and understand research content in a natural conversational way; connecting to the internet to get fast, timely, trustworthy answers with links to relevant web sources; comparing the responses of multiple models at the same time (such as o3, GPT-4.1, Claude-3.7, and Gemini-2.5); and providing a convenient toolbar for quick questions and quick actions on text and images.
How to use: first download and install the Haye app on a Mac (supports Apple Silicon and Intel devices), then configure the service—you can use the built-in service or configure your own API key, and Haye supports a variety of mainstream models; after that, you can invoke it at any time via the Command+E shortcut. In addition, users can customize preferences such as language, response style, and AI model, and can create personalized styles and set custom shortcuts to execute style settings with one click.
Use cases: suitable for macOS users who need to invoke AI at any time in daily work such as writing, reading, translation, study, and research; especially suitable for scenarios that require chatting with local files (such as PDFs), need internet answers with source links, or need to compare outputs from multiple models at the same time.
Limitations and notes: Haye is only for the macOS platform (supports Apple Silicon and Intel). The FAQ on the official website page lists questions such as "How does it work," "How to get updates," "Which models are supported," "Can I customize the models used," "What information does Haye collect," "Why is there no free version," "What is the refund policy," "Which systems will be supported," and "Is it an Electron app," but the page does not provide specific answers to these questions, so the relevant information is not currently available. The feature of remembering users' previous interactions and preferences and gradually personalizing with use is marked as "will belaunched in a future iteration" (Launch in a future iteration), and whether it is currently available is not yet provided.
