Haye is a system-level text assistant for macOS. Whether you're switching between languages while reading technical documents or need a faster way to translate, summarize, and rephrase, Haye brings these workflows into a single floating window.
Just press Command+E to invoke Haye from anywhere on macOS. Select any text to instantly get enhanced reading and editing options. Chat about what you're reading without losing context, and convert text into a more familiar format with one click, no matter the language.
The app features a fresh interface aligned with macOS visual style. Enter your API key from providers like OpenAI, Claude, Gemini, or DeepSeek to use their models. The Style feature lets you create customized prompts that align responses with your preferences.
Haye works with PDFs and local files, provides search with free access, and integrates smoothly with your desktop applications. The simplified toolbar makes it easy to access these capabilities while editing, creating, and reading. You can use models like GPT-5, Claude Sonnet 4.5, or Gemini 2.5, compare multiple responses side by side, and customize your workflow with rules and styles.
You can configure your own API keys to save costs, and Haye integrates with system functions like time and scheduling. Grab the latest build from haye.ai.
