One sentence. One app. Your machine.
Onyx is now open: describe what you want in plain language, and it creates a local app that runs on your machine. Custom abilities let you control anything your computer can do — no cloud required for the core experience.

Create apps with a sentence
- Describe your idea in natural language; Onyx generates and runs it locally.
- Define custom abilities to interact with files, system tools, or any capability on your machine.
- Everything runs on your device — private by default.
